could i just torch the flanges off of my manifolds and send them to ftp? or would i have to look for unused flanges.

 

look at Kar Kraft (734-422-8510) they had some for 60 bucks a month or so ago. ir just ask tj at FTP to get some. i know they sell them where he got the 2v ones...

 

Yes it would. No it won't allow you to run 4.6 LT headers. In my experience they just won't fit without substantial modification. The manufacturers didn't seem to feel like making them as compact as possible. FRPP's are better than stock but not much. JBA are about the best in a shorty. If you're doing a 4v, then I'd stick with stock logs. I've seen personally 440rwhp through stock log type manifolds on a 5.4 4v.

Adapter plates and you'll have to drill a hole in the block for one of the coolant passages. Look up 2v-4v conversions and you'll find that detail. In any case, good work man. You'll need to get a 4v 5.4 front cover. Navigators had them.

For the most part.. They're worth maybe 5-10hp on basic builds but the stronger the build the better the exhaust needs to be. Shorties are a stage better than iron logs.

You'll want a proper steel flange. You can't weld thick *** cast iron to thin wall stainless steel very well and with longtubes you want a good thick flange that can hold some serious stresses.

 

Drill a hole in the block??? Even though mines a 4v block to start with? And I found a complete diassymbled rebuilt 5.4 01 navi engine minus the intake but with custom blower cams from another source. Maybe ill just take the 2 and get some plates and bolt together that way. Only fear is without forged internals it may go boom. So what's the limit here 450ish??? I'm steady working on it

 

navi motors can take upwards of 500hp from what i understand. the magazine run a stock one with twin turbos without blowing it.

 

Pretty much all stock 5.4 blocks can handle that kind of horsepower. What they can't handle is RPM. So if you can find a way to make 500 hp with less than 6k RPM, do it. IIRC the Lightning shortblocks have forged pistons, but the same sintered metal connecting rods, they are rev limited to 5250. The newer 3V engines have extended that RPM limit to 5400 but that is still with the same rods. I have been running my combination up to 5800 on stock rods and dont plan to spin it higher. It really does not make sense for me to run higher because the power is dropping off after 5300 anyway.

 

I thought for some reason your donor block was a 2v block. Don't worry, just bolt up the heads and adapter plates and use a cobra or mach 1 intake. Enjoy. As a rule 4v motors can spin a bit faster than 2v, don't know why. But that only goes for stock motors. Replace the rods and bearings and you'll have a pretty durable combo. If you toss in pistons, well then you have a pretty bodacious platform to build on. Blower cams are for blower cars even if they do help a little over stock cams on NA cars typically.

If you put it in with stock internals then limit yourself to <6k rpm. You can still probably easily get away with a 125 shot of gas after that and hit your 450 mark.

w00t to that. You can pull ridiculous power out of the modular blocks. Any of the post 95 iron mod blocks will take 1000hp or more properly prepared. With the H-beams and h-series bearings I don't really worry about the bottom end much as far as rpm goes (a good balance job is important though). The top end, another story. It was only good for 5500 before power fell off. Dunno about with the blower.

 

So if I use the navi long block and the cobra blower set up with adapter plates and keep it under 6k rpm and moderate boost I should be ok? =) and poss fit under a cowl hood?

 

with adapter plates you will probably need at least a 4 inch cowl. im doing the 4v and i may or may not clear the hood without k member spacers and im gonna be using my stock intake just widened, you've gotta add up the height of the blower plus the the inch or so for the plates and what not. idk if you'll need a 4 in hood for sure but dont plan on runnin your stock hood.

block for 99 bucks in sc...

 

I was hoping that r hood and maybe my scoop on top would clear... painted the same color it would hoplully maintain some stealthness

 

Well, I finally got to the track! I haven't had a dyno tune so I have no idea really where my A/F is. I decided to roll the dice since I have been driving it all summer. I'd like to scan the timeslips so you guys can see them but I don't have access to a scanner. I may take pictures but I don't know how well that'll work. ANYWAY, I ran a best of 13.39 in an untuned 3705 lb convertible with an auto trans. I'm actually pretty happy with that. I only have a 2,400 stall and I was getting pretty consistent 1.92-1.95 60' times. The MPH was about 101-101.5 every time. That should be enough info for r3d to do some desktop analisys on some HP figures. It took a little tweaking with my SCT programmer on the shift points bec. I kept hitting the rev limiter on the 2-3 shift. My best run was after I got that handled. All runs were on a hot engine also, may have been a little better if I was able to let it cool down. I ran a 13.42 a 13.45 1 13.51 and then a 13.39.

 

works out to 305-315hp on the ground by the numbers but that's not a quotable number. good and ballpark though. great times, puts you right up there with ls cars

 

what are u running with?

 

how much spin are you getting off the line?

 

No spin, even on street tires. They prep the track pretty good where I go. It is a 2000 convertible, 5.4, 4R70W with 2,400 stall, patriot stage II heads, comp cams 270's, JBA shorties, off road x pipe, welded in flowmasters, HPS intake, C&L plenum, 75mm Roush throttle body, JLT fenderwell cold air intake, 24# injectors, stock MAF, SCT programmer, 3.90 gears, 3705 lbs. with me in it and 3/4 tank of fuel (as it was when I ran)

 

Also, I was crossing the line at only about 53-5400 RPM. I think I should have chosen 4.10 gears in instead of 3.90's.

 

what was your 1/8th time?

 

8.56@81.3 8.68@80.78 8.59@81.06 8.63@80.65

 

so u just have stock internals, nothing forged

 

not to bad at all.....

 

It is a 97 E-250 engine out of a wrecked van. I stripped it down and inspected it, put the above on it and put it in. Stock, used bottom end.

 

DAUMN!!!! That's awesome congrats now go get a tune lol! Post like these make me wish I had a credit card =)

 

well, if all goes planned this weekend my car goes to FTP for headers, mid-pipe, mounts for the turbos, intercooler piping.

 

get a dyno tune. I'm sure you'll touch 12.99's if not better then. but as is, thats not bad at all. it's almost a drop and go motor. can't wait to get the Vic done, HPS intake, Trick Flow 38cc Heads, 11:1 compression, 5-speed Manual, longtubes, ect...The car will weight about 4000lbs with me in it so your times give me hope.

P.S. don't forget to Laugh with an Evil Grin when you show those Z28 Verts your tail lights.

 

Just checking in with you all, I finally finished my victor jr cut and weld project but havent started the car yet. Had a pin hole leak in the water crossover and had to take it back off to tig it. Should be running next week. The intake looks pretty awsome stretced out. I also had to do a butt load of porting to get it to match the full CNC ports on my heads. 1/4" of material in about 75% of the intake ports. Made a 3/8" alum adapter to mate my elbow to and also removed egr flange and drilled and tapped it for water/meth injection for the T76. I blew the stock intake apart at 17psi so this project is getting rushed sooner than i expected.

 

post pics man!!!!!!!

 

does anyone have a picture of the front of the navi engine without the timing cover? ive been looking all over the net and cant seem to find one. i need to make sure the 4v guides im getting ready to buy from napa are the right ones. i also want to see how they are attached to the block because the navi block doesnt have places for the guides like my cobra block did. if anyone can help me on either of those issues id appreciate thanks

 

Alright I got 04 cobra heads and cams with the entire blower set up and smaller pulleys 60# injectors acufab single blade throttle body c&l, jlt ect u get the pic (ill try and load some pics tomorrow). Anyhow. Still working on the other navi long block w blower cams if I get it ill sell the short or long for a fair price ill just be using the front cover and blower cams from it. I'm going to for go the stock rods and pistons and just buy forged thus the reason for letting second one go. I.e. the funds for my bottom end. =)

Alright feel free to chime in what kinda power ya'll think ill see with this setup??? 9.1 comp? With cobra 4vs and cams just for arguement sake. And the smaller pulleys thru stepped long tubes and. Offroad thru flowmasters. I'm thinkin 5500 to 5800 would be as hard as id push if it even need to go that high. The set up on the cobra was pushed to 15lbs I think??? Maybe ill polish the blower and heads but idk.... and eventually I'm going to step up to a whoopa I want it to run 1st....


Rest of the car getting irs and cobra r brakes. Ill have to be easy on it till I can afford the 6sp too. Going to do mach1 styled seats with custon orange bars in them to keep the theme thru out along with the gauges and finish the outter with the cobra look... after seeing r3ds car I'm going to do a full detail under hood. I got some sick ideas... I wanted a simple swap but life has handed me something more so I'm going to take it and run with it... it will be a nice day only car I guess seeing how my wifes 07civic will be paid off next yr and will bw my new dd while she buys another new family car lol! My stang was in mm&ff about 2yrs ago with her next to it and now I want a full shoot on my stang when its done


So any power ideas I'm hoping to see well north of the 500 area both ways. I guess only time will tell

 

did a little more work. Plumbed up the heat exchangers (yes plural). There'll end up one on either side just behind where you'd expect to find cobra fogs. Finished up a little more of the vacuum line setup and cleaned up the install a little. Plumbed in the methanol delivery line and nozzle. Finished chopping up the hood, it should clear pretty much whatever now. Finances are farked for the next month so it looks like it'll be down till winter. Grrrrrrrr.

Going hunting today. Probably make more progress tomorrow.
