Mileage is a consideration as I am interested in an all arounnd car. Handling, power, braking, looks, mileage, throttle response. I will put all of the needed effort and questioning into this before I do what I did with the 4.6 and not get much return for the cost. What about YOUR mileage?
I am not a Ford guy and if this was not a convertible I would not own it and even then I would sell it for $9k. and lose $6k+. It's in the classifieds and advertised locally and I also received a new set of cams monday. It sells, fine, I go 4.6, fine, I go 5.4 even finer!
Anyone have a very nice '88/'89 Chrysler Conquest and cash? Auto preferred. Someone steal this car and nmake it easy for me!

 

i used rtv only between the adapters and the head. never had any issues. my adapters have the holes drilled in them i believe...

 

hey r3d could you link me to the K-member spacers you were talking about? i may just go that route with the intake adapter the excuses and delays from HPS are a little frustrating to say the least

 

has anyone tried to contact trickflow? i just sent them an email maybe they would be interested in modifying their 4.6 trackheat intake for the 5.4

maybe even sullivan would be interested in doing their intake with modified PI intake runner mouths?

 

Summit owns TrickFlow and they are suposed to make a 5.4 version due this summer but the guys at Summit should know if it is still a go. I don't think the 4.6 version was very successful so don't know if they have droped plans. TrickFlow was also supposed to make a dual TB aka the Bullitt, SVO and Cobra's also, cool if they did. There are a lot of 2V's out there but I am afraid they are going to be left behind with the success and simplicity of the new 3V's. Heck, the 2009/2010 V6 is slated for 300HP so we will have be careful, not against Challengers and Camaro's with 371 and 347 c.i. motors but our own Ford V6! Ford has made V10 351's and 390's with the latter making 605HP. I believe they were 4V's and SC'd so noyt likely they will make prduction but a 281 cannot keep pace with a 371 or 347 which is just a detuned Vette motor with a TON of parts to make it a n500whp NA motor.
Me, comfortably poor so no big deal and on the downslope of life. Would just like the 5.4, torque and a 13.5 on streets.

mine is also in the classifieds, check the pics, I'll drop a $1000. from the price but the stock wheels, intake and UDP's go on. Still a steal of a deal! Sell or 5.4, whichever comes first.
By the way which brand of adapter plates are considered to be the best out there for the swap, anyone? Mark
PS: I ordered a new rear differential today as I will either change the 4.10's to 4.30's or 3.27's depending on whether I go with a 4.6 or a 5.4. I don't expect the car to sell as they are a dime a dozen unless you have a Bullitt, Mach 1 or Cobra, '03/'04 version.

 

the spacers are not a catalog item. You have to call. That's intended for 4v conversions really, just to solve the brake booster clearance issue. You don't need them on 2v normally.

I pinged Bob and let them know the indians are getting restless. I usually hear something back from him a couple days after a ping.

 

BTW... I reset the poll as requested some time back.

EDIT: Well that was a bust. I can reset the number of votes but not let anyone re-vote.

 

How about then guys who have the swap done or have the parts and mocked up the deal list the parts/vendors you have used. I am really not clear on th adapter plates, guess I am thick! Professional Products has some, machined for $199. I saw another neme, cast, more like $269. and think I read about a third in my google search.
I think my Crower stage 2 for npi should be fine for TORQUE, not sure about intakes as I don't know how well the stock TB/plenum fits as that would be better for torque but is a 70mm TB enough for the 5.4? The SVO had dual 57mm blade TB.
Who knows without a doubt what compression flat tops and 4.6 2V PI heads will give? Sullivan is a 4V company as they list the PI head with the 18cc dish that I believe we have giving 8.8 and I iknow we are at least 9.3. I can't even find what a simple PI swap yields the npi guys with their pistons and our smaller chambers! 10.4? 10.7? Anyone?

To repeat, www.hitechmotorsport.com has a cam that adds 45whp, yep, 45whp, more than any other stage 2 type cam I have seen on STOCK HEADS/INTAKE with just LT's!! 300+WHP w and they tune ONLY with 87 octane, usually about 23* timing. What timing do you guys run? My 4.6 does not like more than 26* anyways so I figure a 10.5:1 with 93 will be OK, opinions? Lots of data with vendors and numbers achieved would be nice along woith some pics. THX, Mark

There were numerous other companies and individuals involved who've been ludicrously helpful. Among them, the following deserve special mention:
Bob Hardin (HPS), TurboX2, Saleen S330, Myillwillinc, Al Papito and Richard Holdener (via his many literary contributions).


As for your motor, done up with stock pistons and rods and a nice stage 2 cam on at least port matched heads and any proper intake (even one with adapter plates) will be a crap load faster than it is now and have much improved part throttle.

You can drop down to a 3.08 gear and reap some gas mileage benefit without sacrificing too much grunt (I'd stay with 3.27's). Your compression will depend on the compression height of the piston. If you use a flat top designed for a 4.6 then you'll be running about 11.5:1 plus or minus a couple tenths.

 

Red, some good info. I like the ebay company for the pistons and rods(2 lbs. lightter than stock?, that is a lot!) though I doubt flat-tops and my PI heads with 44cc chambers would give compression that high, maybe 10.x:1 as the 5.4 pistons are deep in the hole for some reason, .100". That is one to confirm 100% as the stage 2 Crowers for npi heads are not huge and might not bleed off enough compression at WOT to prevent knock. Larger cams can handle more compression as they have enough overlap to lower the cranking compression, thereby lowering the chance of knock. Maybe Sullivan will help with that one. Polishing the chambers and using a 180* stat and a 1 range cooler plug will work also.

Adapter plates are still a bit up in the air. Sounds like the Pro-products are decent but need to be port matched better than they come? Then you say the fit is "touchy". Can you explain that in more objective terms? It seems that the plates( ALL are touchey for fit) have to have the bolt holes aligned better, would taht be fair? Do these plates bolt to the block and then the intakes bolt to the adapters in different holes or the same holes for the intake, through the adapters and into the blocks? My SVO would NOT work. It has the COP mounting bosses/bolt holes as part of the intake, they would place the COP's up too high off the plugs. I have forgoten what the stock intake looks like with the COP mounting. I would want that anyways for the better torque as that SVO would be great forn a 5.4 that was being built for max power. Even with adapter plates it would likely blow the HPS out of the water, no offense intended. Huge plenum and runners, best over 4000rpm.

OH, Comp recommended a set of XE262AH cams for me and what I want to accomplish with any motor I build, 4.6 or 5.4. The Crowers I have are about the same cams, spec for spec. If I did have to do a 4.6 I might go for a screamer and go with 4.30's and a set of Hitech stage 2's which add 45whp, more than any other cam I have seen for stage 2 specs. They are different for sure. However several guys I PM'd who had them confirmed whay Hitech claims and made 300+WHP with STOCK HEADS/INTAKES! LT's being the only mod! Amazing. .050" and 4* more lift/duration on the intake side which they say is the weak link in the modular head. The intake side!
I ordered a new rear differential limited slip 8.8" unit today, $175. $45 less than a leading catalog vendor! Whether I remove my 4.10's for 4.30's or put the stock 3.27's in will be determined at a later date.
For anyone interested in my car I have lowered the price to $9k but the stock wheels and intake go on and the FR5's, wide tires and SVO come off. That is a $1000. drop. More to drop soon if it does not sell so act soon or it WILL be gone! THX RED, mark
PS: Yes it i for sal nd I am buying parts for the future as I really don't expect it to sell even for what I paid for it myself, minus the mods, a few anyways, most go with the car.

 

motor is back out....... yippie....

 

so what do i do if i want to put a turbokit on a 5,4 2v, if i do the swap??? i really like the idea, and since i like gas to i'll prolly swap in some lower gears, but the turbo is the main thing im worried about. will i have to do a custom kit??? i dont know how to do any welding, so will i have to get a shop to do it for me???

 

r3d i want the k-member spacers for hood clearance, i have an NX plate that is about 3/4" tall that fits between the upper and lower plenum's and i want to use the stock hood


and according to email trickflow ****-canned the 5.4 intake manifold they were going to do, they are moving on to 3v stuff

 

I still don't think you'd need it with the HPS intake (maybe a notch but not a hole). If you really want the spacers though just give MM a call and let them know you want some 1/2" spacers.

I'll put an email in to Chuck Schwynoch (MM's CEO) and let him know that more people are wanting the spacers. See if I can talk him into getting them up as a full time item.

for the most part you should be able to use existing 4.6L kits BUT there will be significant install and fabrication anyway even with one of those kits. They are far from a bolt on mod in the best of cases. Figure on about 2 grand in install costs for a turbo. A blower is significantly more cost effective and nitrous is usually just easier to deal with all around.

 

i don't have time to wait till next january for another supposed deadline for the hps, i start medical school july 28th and i need this project finished up by then...i'm just going to use the rr adapter plates, and the plates with the nx plate i will need the spacers i'm pretty sure

 

yep, sure will.

 

K... Chuck Schwynoch from Maximum Motorsports got back to me. They're definitely moving forward with the k-member spacers. They've sorted out materials, drawings, and all that stuff. The guy that was developing it for them moved on to another company so he's reassigned the project to another person and brought it up on the priority list. You should see them listed on the MM site before too long.

Who's pimpin it for his homies? Dat wud be me.

 

whats the word pimp? intake and/or headers.......

 

I am considering this 5.4 SOHC option. It's either a 5.4 or a stroker 5.0.

I would use plan on using the forthcoming HPS intake but an email got no response and from the sounds of things it's been delayed due to foundry issues.

Any idea when the new intake will actually see daylight?

No NOS or turbo or blower is in my plan. Just atmospheric.

 

the intakes are currently being produced and readied for sale. They will not be released to the public until after the first batch is ready to ship. I've been expecting it for months... so I'm not going to guess anymore. Now I'm just hoping for this summer.

myillwill... I don't even know what's up with anything on the header front. I'm going through some employment nightmares right now but a new job is on the horizon (maybe with Penthouse ) ). I'm goinig to the shop today to do a little gauge work so I'll check on the headers and see what's up.

 

Suweet just when i was going to put my 5.4 stuff up for sale

 

how about r3d gets his super slick ninja suit on and slips into the foundry and gets some smooth spy pics of said intakes.....

 

Hey tommy... Update on headers. We've got a set of proto's coming back hopefully end of this week. Going back in on the 13th and leaving my car till it's done. LMK if you need yours back in any kind of hurry.

 

No luck finding a 5.4, however www.karkraft.com has a 5.4 assembled shortblock with flat-tops but he said my mheads would not work/fit, I believe because the pistons are tryly flat-tops, NO NOTCHES for vaolves. I was also told the front cover between 4V blocks and 2V's are different. Now I am confused, no make that even more confused.
They also had a used Mach 1 shortblock for a good price, same issue, flattops and they used a different front cover.
So there isn't anyone using a block that had 4V haeds on it now with 2V's? That means a 2V 4.6 aluminum is not a possibility or I would need different pistons and some here to fore unknown, actually still unknown, front cover?
How about a 5.4 short block with flat-top pistons, PTV interference? Can the pistons be notched or is there not enough material there?

Now Crower says the npi cams I bought with .532"/.532" lift and 220*/224* duration at .050" on 114*LSA are not the best for PI Mheads and I should have gotten stage 1 for PI's, .540"/.549" & 216*/220* on a 114*LSA. I realize the ramp is a bit quicker with the PI lobes but that much?
My currect SHM #2730's have .495"/.495" & 230*/230* on a 113* LSA. I would have thought the Crowers would have been a much better all around camset, more lift, .037" in/out and 10* less intake as the SHM's killed the bottom end. Is there annyone who knows the SHM#2730's advertised duration or even better info from the cam card?
Looks like I have a NEW set of Crower cams for sale.
As I stated in another thread I have a 2 part story Hitech did on a 5.4 against a 4.6 and with a PI intake the 5.4(OH, also a tune, leaned it to 13:1AFR and usually they tune for 23* and on 87 octanre but not sure about the timing.
The 5.4 made 95lbs./ft. of wtq more at 2500rpm, 12" wide rims fot the new edge with 345/17's?LOL to repeat myself. WOW, that isn tire shredding torque at 2500rpm, smoke included I would imagine. The tune also had the 5.4 at 30wHP more than the 4.6 also. But a 4V 5.4 will NOT work? If it would what changes are required? Anyone?

Another tidbit of FIY is that nthe 4.6 and the 351 Cleveland have the same cylinder displacement/intake valve diameter number, about 20, meaning that they both should have a cam around a 109* LSA with extenuating circumstances of course.
What it means is the 281 has big intake valves for it's size. If anyone can sort thru this I would appreciate some info on the head/block/front cover combo's and possibilities! You get a star too!

 

most of your questions are answeed in this thread. you might have to read thru alot of it, but it's worth it.

 

K... you gotta relax. This isn't that hard. Trust us on this. You just want to use your flat tops right? It's actually very easy and your cam ain't going to be a problem. It's going to make solid power in just exactly the way you want it. I'm putting a dyno sim together for the instructions I'm about to give you. I'll PM you a link when I'm done.

Step 1: Buy the motor from cobra1923 listed in the classifieds. It's a 98 navigator (2v) motor. You'll use your existing PI heads so don't worry about the heads. Then you'll have all the big you'll need at a screaming deal, even with shipping involved.

Once you've done that, come back and let me know and I'll give you step 2.

 

Red, I don't kinow whnat the program you have uses but the SHM's have only .495" lift, in/out and 230/230, yeah goog duration but terrible cams at least in this tired 4.6, Added the SVO intake and SHM's and went .4 slower with a tune. Changed to the 3400rpm stall and got back to the typical 14.0 @ 100mph.
Better tune from Brenspeed locking after each shift dropped .2 to 13.80's.
I was thinkinhg Hitech stage 2 at .550"/.500" & 234*/230* on a 111* LSA-2* or their stage 3 with 238*/234* same lifts as the 2's.

I'll check the classifieds.

 

comparing 4.6 to 5.4 with these parts is a waste of all of our time. You're only going to confuse the issue. 5.4's respond differently to the same parts.

In this case lift is irrelevant due to head flow and duration. Either of the hitech cams won't make much of a difference. Use the cams you have and if you want more lift, shim em'.

 

Cams w/ less exhaust duration and lift? Did you maybe switch the numbers around because I have NEVER seen it the other way around.

 

R3D do think these manifolds would clear for my turbo setup ?
