I would take a termi if I could find one that met my requirements but I have a better chance of hitting powerball - and I live in NV
#3154
I'm pretty set on the GTO right now, a Marauder wouldn't do it for me, it just wouldnt.
r3d for a termi it has to be under 38k miles, in NV, at a dealer, priced in the low 20's - and thats just not gonna happen, even with 36k miles they are still high 20's private party..

24 lb injectors are good for 345rwhp/332 rwtq, i know our club has a bolt -on 05 gt making that poweron No2. stock pump, stock injectors. other bolt-on 05+ make 310 rwhp/310 rwtq with stock 23lb injectors. ev-6 stang and truck motors use 23lb.

my 21's hit 90% duty cycle on my dyno runs. Granted it was running really rich. I'm planning on 350/350 or thereabouts plus 200hp worth of nitrous. The 32's should make my life a little easier and the new pump is kinda mandatory for any more power than I'm making now.
281.. would you consider a Cali car if it's otherwise meeting your criteria? May be able to help.

You SURE can. I'm using a tall plenum (Pro Products) as well so there's some added height from that.
RR adapters are just about an inch thick. You'll just need to chop a hole in the underside supports with a cutoff wheel or jigsaw etc...
Good high contrast shot of the hole. The white is the underside of the hood skin. Don't worry about weakening it... it's plenty strong.

He's been pretty much unreachable which usually means he's busy making it happen. It's definitely approaching. Don't count on anytime sooner than January though, and that's a best case. Once they're cast they have to go through machining and finish work to be ready for the door.

4.6 and 5.4 2v's use the same head gaskets/bolts correct? I am doing a stock build and was looking at this kit http://store.summitracing.com/partde...6&autoview=sku
I know its allready covered in here but damn if I can remember what was said. Thanks!
Also, anyone know the chamber size of the navi heads and chanber size of the PI heads? I am putting the PI heads on the stock navi shortblock and am trying to see where the compression is going to end up. The navi's use flattops FWIW. This engine is getting slung into the car until I am done with the high comp, high rpm navi headed beast. Really what I need to know is what CC the chambers are, if anyone happens to know. Thanks! Best I can tell should be at around 11.2-11.5.

With flat tops you'll see like 11.3:1 on PI heads. You'll see about 10.1:1 on 4v heads. If you want to maintain the same compression on the 4v heads you'll need a 6.5cc domed piston.

Thanks again!

avoid 4.10's... traction is not possible with them. Try 3.73's as a maximum and those will limit traction up to deep into 3rd gear. 200 shot isn't too much as long as you keep it above 3000rpm for activation rpm.
Even in 2v form... the numbers aren't big but the actual performance is startling.

I was not aware that any other tire other than a slick would fit a mustang wheel?

i use hoosier 275/50/15 DOT pros, and they don't spin unless i stall the convter to max.
also i just purchased T-6 2.5" x 1" x .065 thick aliminum rectangle section tubing. 24 feet of it. with the 12" x 20" plates i have laying around and 8 injector bungs, i do believe i am quitting the adapter business and am just going to copy the 5.4 3v intake on modular fords.com
i need to find trumpets to match. more later. i will be done by march. i am indecided on the specs yet. too many things to decide concerning the application. ie, all race, or street performance, or torque with moderate HP.
runner length and plenum volume are the only two variables i am considering right now.

Goodluck dude and keep us posted!

Forgot to give you that link, they sell hard to find parts(velocity stacks, etc..)

nice link. Great work!
Richard Holdener got the same results with large plenum intake runner lengths that I ended up with for the HPS 5.4 and my current 4.6 intake: 9.5" with a proper cam and proper runner volume makes for 4500rpm peak tq, which is about perfect for a street car.

Little update for anyone interested
Got the 4.6 tore down(question on that shortly)
Tore the navi longblock down last night, bottom end checks out(rod side/side, rod bearings and crank bearings) it all looks great matter of fact. However, damn at the carbon buildup! Damn passenger cars/SUV's not being driven like they should
Doing a quick portmatch to the heads now. Gonna see what a stock swap will do with the added compression.
My question, I thought all 1999 gt's used a 6 bolt crank? Kinda hard to tell but I beleave the damn thing is forged(like in a cobra) however so much crud on it I cant tell as of yet fully. WTF is going on here?

Sorry guys, I'm dropping out of the 5.4 project! I have heads and forged crank from a 5.4 Lightning Engine for Sale: https://mustangboards.com/mustang-cl...tml#post297822
