Default How much modification to get 300 - 350 hp out of a 88 GT?

As the topic states I am curious how much money would I be looking at to push 350 or so rwhp on a 5.0?

I would be doing the work myself. Avoiding Nitrous though, what mods would get me there?

Thanks

Cam, heads, intake.

you can buy the trick flow kit for like 2400 that suppose to give you 350-360 depending package, but i think your block has to be bored to get that.

Good set of heads, with a good intake and cam would get you to 300.

A good H/C/I will net you around 300rwhp. A 331 or 347 with a good induction will give you 330-370rwhp. Bolton's plus a supercharger@8-10psi will give you 330-370rwhp. As for price, it all depends what route you want to go. But it won't be cheap.

Trickflow overrates that at the flywheel. Many of their kits put down 270-290rwhp.

I figured as much. I was reading the fine print and it says to get that hp your block needs to be a 306. Probably need the right pistons an so on.


I got a 331 stroker, an its very expensive and the f*ucker don't even run right lol. I have to drop another 800 for some crap to see if that will make it all better.

Thanks for the answers guys. I'm looking at 87-93 models right now, but should I also take 94-95 into consideration? I've always heard the 5.0's were the best/cheapest to mod when compared to the newer stuff (4.6 SOHC), so as far as the fox and sn95 are concerned, are there any huge differences besides the fox being ~75 lbs lighter?

Not much difference. You just need to figure out which body style you like more.

So not much difference in suspension, rear end etc?

One won't handle more power without extra modification than the other?

Generally speaking, is one easier to work on than the other? Easier clearance to the undercarriage, better layout, etc etc?

I'm not worried about the looks per say, I think they're both nice cars, I just want to get a good starter. This will be the first 'project' car of mine.

the frame and suspension was virtually unchanged from 79-04... many use the same or similar parts. It ultimately comes down to which one you like better (looks)

Fox would be better for the easier to work on part. Foxes are lighter but the 94+have bettre brakes and suspension and are 5 lug.
