wow sounds like he should swap the stock cams back in. lol thats why i want this motor so bad. It looks so stock. Anyway, you could do that thing with the removable cats and just put them on for the sniffer test and then take them off, or run really high oct and it burns way more efficiently right? i don't know that much since i'm on east coast in NC and the inspector just ask if the signals work and how about the horn lol.
You like the stock look, how bout this dudes stang?
#1297
why would one do that...that shows off what you have (sort of)...i don't know i dont' think it looks all that cool....but that's just one opinion...thanks for taking the time to read this....
#1298
thats what i originaly wanted to do. that is soooooo baddddd assssssss. I rode in a car with the swap like that and it had a some "how would you say....traction problems" but it was hellishly fast , fast , fast, fast , fast .....
#1299
What do you mean stock drive train? as of the moment the car has the stock npi 4.6 with just a little mods done to it. Its a cmpletly stock auto and rear. so basicaly stock.

No problem man, it won't take to long for me to gather everthing up ,money willing, and slap it in my car. But after i do that i'm deffinitly getting a tune and a converter. Tell me guys, what gear do i need to run with this car with my 4r70w? a 3.73, 3.90, or 4.10?
#1302
I'm using 3.55's in mine. Any more than that and traction becomes too much of an issue for my tire budget to handle. I figure, 280tq now, probably 350 or better post install... definitely not gunna be able to afford 3.73. Saleen S330 had 3.73's and zero traction outside of 4th gear with 366tq.
In any case I think the smart money will be on a good size air:air intercooler. You've got enough heat and metal under the hood as it is with an oversized motor and a big old blower, may as well not add to the density issue. ATI makes really nice coolers. You'll need a kit of boost pipe bends and lengths to get it installed and the battery will probably need to be relocated.
I just picked up a set of superior axles (finish off the upgrades to the back end), white face guages(cheap... why not) and billet fuel rails. I need to find a set of 32lb injectors on the cheap and then I'll have the intake setup completed. The days are zooming by and I'm not making the progress I'd hoped but soon... sooon. Famous last words.

You are talking about 400+ ft-lbs coming out of the engine at rpms below 3,500-4,000 rpm w/ a torque curve that's almost flat. Combine that w/ a big rear gear and street tires and you will not hook up. You should stick w/ nothing more than a 3.90:1 rear gear. The torque alone will make up for the lack of gearing.
#1308
if you're going to use ET's then get as beefy a rear end as you can. I'd go up to 31 spline and aftermarket diff... regardless of the gear with that tire. You should also have a driveshaft safety loop installed. 3.27 is fine if a little long. I like 3.55's better on my 4.6 and with the 5.4 they should be more than sufficient. 3.73's on an auto would be a fuggin h00t. Beef up your tranny or you'll frag something. 3650's are teetering on the edge with a 5.4... 4r70w needs some help if you're going to race it.
#1309
ohh.... thought you meant a viper spec (like the gearing). a pullout from a viper, I seem to recall that's a bellhousing and tailshaft housing away from working. Of course there are crossmember issues and you have to deal with the clutch. Viper clutches are hydraulic. I don't know how much of a conversion issue it is outside the bellhousing and clutch fork.

I don't know if they'll plug into my harness... If they will (even with a little tinkering) let's work a deal.
VOID... The rating is more for where you can expect breakage. Accelerated wear and subsequent breakage is another story. I recall reading in another thread on here about some people getting broken input shafts on the autos. I'd leave the converter alone or just get a stronger built one with the same stall RPM... your peak torque will start coming on right about where the stocker stalls so it's not a bad one from that stand point. I generally refuse to deal with autos so I'd recommend you tap one of the guys here that knows their auto-stuff.

well guys, remember back a few months back i had decided to sell all my 5.4 2V stuff. well i didnt sell anything, so i guess i am back in the game. i might take the block to the machine shop this week. i am still undecided as to get a set of aftermarket heads or just put my hand ported PI heads that are shaved .03 (which currently house Comps XE268's), or hand port my factory PI heads and install the Comp 270's i have. everything will be forged, to yield about 9.1CR, and about 12-14#'s of boost. i found a shop that could fab my Mac L/T headers to the 5.4.

In any case... those seem like a decent option. LMK what you're looking to get out of them and what kind of use they've seen.
