I am putting in a new motor but not sure what to do. I want at least 600rwhp on a daily driver. I was thinking about a 5.0 or 5.1L stroker kit with a T trim. I'm just not sure on what I need to make it reliable?

everyone has brought up jsut about everything you need & your plan sounds good. BUT everyone has forgot about the most important thing so far............. FUEL. do not skimp on the fuel system

I already have the aeromotive return style fuel system so I think I'm covered as far as that goes.

I just talked to VT and was told a forged 5.0 shortblock with billet oil pump gears will run me $4k. Anyone know if I should go with 8.4 or 9:1 compression?
Well, if you're going with the blower right off the bat, then go with the lower compression ratio. It will allow you to spin the blower a lot harder while resisting detonation in the process. I’d personally skip the stroker idea and just go with a good forged rebuild. You’ll see 600rwhp with that, a nicely worked set of heads, some supporting pieces (on both the intake and exhaust side) and a healthy amount of airflow from a T-trim or Novi 2000. :nice:
 
19#'s on KB blown Cobra does 600rwhp if the tune is good.

other than that... your gonna need the best bottom end you can buy and the most inches you can get. inches helps...

also look into a turbo setup... much better that way. more reliable and makes more power. 600rwhp is a ton out of 4.6 based motor... i see a turbo being the best bet... twin turbo GT is pretty sweet...

here is a twin turbo Mach I

i know the lady that showed me this car.... she is on another forum...and is with induction concepts company that made that Mach I TT and did her 95 GT with her/their kits.

their base kits are 600rwhp at 8-9 psi... and very nicely done. Her Gt has the 800 horse twin turbo setup. very cool people, do a great job on making turbo stangs.
you will need to built up the bottom end tho, and a 5.0 stroker with their turbo setups with mild 9psi would absolutely RIP on the street/strip making 600rwhp easy

heres the sight for the 96+ Mustang setup

their base kit is abit pricey at 8700bucks + shipping, but its a COMPLETE kit with up to 1000hp capacity.

speed costs money... how fast do you want to go?

their are other kits for less, like in the 5000$ range, but i am not sure whats all included in them. i forget the site i seen it on.

kenne bell kits go for 5400bucks for the blowzilla which is what your gonna need toget that power. not bad, but still not as street friendly as the turbo kits

also, check out these guys

I'm not sure how you come to that conclusion. Nothing is more street friendly that a positive displacement blower. Either way, I would go the Centrifugal route and do it cheaper still. But that's just me. I don't drool over the KB's like others do.
 
Joe what's up with your current motor? I would think that with some new pistons to lower the compression that you could reuse the rest of your shortblock.

And you just finished up your current set-up too, lol.

Best of luck with all of it... :flag:

unless its a turbo...

blowers are run off the crank pulley so are constantly stuffing air into the motor, at all rpms.

turbos however build boost with exhaust gasses as rpms go up, so at lower rpms, its not boosting much at all compared to the blower. and i have yet to see 800-1000rwhp+ blown streetable cars that are as streetable as a turbo setup with same power. just my view of things and what i have see throughout the years
