How much nitrous are you going to be using and how many miles on your motor, and is it the same as mine?

I have been looking around and so far came across basicly the same things as a set of heads with cam and intake and 50 or 70 shot would be what I am going to be shooting for unless the shortblock with 126k on it would not handle that much. I just bought a good exhaust system with Flowmaster's and taking it to the track I might be in the market for a good cat-less H pipe.

John did make a good suggestion, by bringing up the Thumper heads. Another reputable set of E7TE based CNC heads are the "CNC Power Heads." Both these and the thumpers are a viable option for those looking to stay under $800 for a set of fully assembled heads. The Power Heads out flow stock GT-40P's. As such, they are a viable option. The only reason I went with the GT-40P's, is that I acquired the pair(newly rebuilt) for $320. Had that deal not come along, I would have gotten the CNC power heads. To get a set of GT-40P's to flow that well, you would be up to the expense of a set of reputable aluminum castings. You are right, that most mediocre sets of aluminum heads will out perform cast iron ported E7's- though the E7's certainly have a place in the market when you address the bang-for-the-buck factor. Though, I guess, when I built my combo, I was a poor college student. At that time, a couple hundred dollars in price difference was a great deal.:nice:
A good point. This is a topic that has been beaten to death many times over in the 94/95 tech forum. Except for the poor college student situation :), I'd save the extra $200 so that the foundation was as good as possible. If necessary I'd skimp on supporting parts.

I haven't kept up to date on the CNC power heads, but I do know that I've seen GT40P's put down over 300 rwhp (case in point -- Visceral). I've never seen worked E7's come very close to that, usually it's more in the mid-200's. You can get a pair of top of the line AFR aluminum heads used for a thousand bucks or so, depending on options, and maybe some TW's for two or three hundred less than that. And that puts them squarely in the same price range as a set of worked E7's. On top of that there's the weight savings.

Who knows. There's a combo for everyone's tastes :).

Welcome i would say like the rest have H/C/I and maybe a set of 4.10's or 3.73's. I would check into the thumper heads they are fully worked over and run about $600 or so plus you need rockers (like alum. heads), these are E7's cast heads and arent alum. but they flow preaty damn close if not better then some aftermarket alum and steel heads and for 1/2 the cost? I will find the site and post the link here for ya. They are able to run in the mid 12's with these heads, and a buddy of mine has GT40P's i beleive and he runs low 12's! But it's up to you and your pockets. If i remember right you should have forged internals or atleast the pistons are??? Right guy's??? So as far as a shot of juice i would say you could get away with a 150 shot with a bigger fuel pump, i'm running a 125 shot in my 95 (but havent hit it yet) do to the tune and now the weather. Another thing you might want to check into is a chip :shrug: But yes your bolt ons will help alot! Cory (SALEENSTER) has a set of under drives for sale or atleast he did? He is very trusting and an honest guy on here unlike some others but you'll get to know who they are. If ya need any welding done and the shops are to full let me know. peace


Tks John. I have a few items that can make somebody some power. Cold air kit, 75mm Pro-M meter along with some 24's. I also have an underdrive pulley set. Items are in sig.

Welcome to the great northwest.

E-7's are decent, but if you want to make power down the road, its better to upgrade to a better performing head then spend any $$ on work for port/valve increase on the E-7's.

Well a decent set of valve springs (at 125k yours are toast), some 1.72s and 10 psi from a used Vortech S-trim can get ya to a nice very linear and usable 350 rwhp. Your gas mileage and driveability in normal conditions will be unchanged. And if your ever wanting more, that compressor will support well over 500 to the wheels.

Boost, its a good thing.
