you're asking a question in the middle of the night... and are expecting an answer in less than an hour... with only 5 people in this section right now... you seriously expect to be answered that quickly?

I'd help, but don't know for sure, and don't want to give you wrong info


give people a chance to answer you before you start saying they don't know anything...

[ThrashN]

I think the GT/40 intake uses a 65mm.

[ItaliStang]

lmao, ok kid, you're lucky people here are generally nice and will answer you right after you say that this site sucks and that we don't know anything.

I asked you to be patient and if you can't do that then maybe it's you that needs to go "sumwea else punkkk"

I would opt for the 70 mm since you are gonna have quite a few mods.

So ok quit saying no one knows anything b/c you are the one asking the question"so you must know it all". Dont come onto these forums acting like a dick..

[Iownastang]

Use the stock throttle body and put that money somewhere else that will actually make a worthwhile difference.........like a real set of heads.

[jonboy2389]

I did read the whole thread. Like I said, use the stock throttle body and put that money somewhere else that will actually make a worthwhile difference.........like a real set of heads. Performer heads don't flow much more than GT40P heads, especially the mid lift numbers. You would see more of a performance gain in a different set of heads than you would with a big throttle body.


A 70mm will be fine but you are looking at about a 3hp gain for $260. That is not very smart horsepower shopping. Sell your Performer heads and take that money and your throttle body allowance and buy some Twisted Wedge or AFR 165 heads. You can find them used all over the place.

nah mannn i just got those heads wit rockkers and all idunno what you talkin about but performers are alot better than e7's and my buddy ran 12.9 with those heads 11.7 with nos.but yea thanx for the input on the throttle body i kno stock wont work as good and some ppl tell me 65 some ppl tell me 70

Alot of people have run 12.90s with E7 heads, so what? 12.90 is not impressive for having an aftermarket set of heads. The Performers are better than E7 heads but like I said they don't flow much more than the GT40P heads especially at midlift numbers. I'd be looking for a different set of heads before a throttle body but its your car, throw parts at it. A stock throttle body will work fine. I've gone 11.50s with a stock throttle body. Cars don't go fast by throwing a bunch of random parts at them.

yah thats cool so it dont seem like much of a difference for the throttle body anyways, but yah i got those heads for 600 wit the cran motorsport 1.6 rockers i beleive so i kno thats a decent deal for aluminum heads and rockers i just bought them like last week so now im on the hunt for gt40 upper/lower next then guna order my cam n lifters and everythin else

That is a pretty good deal.

[demonicus]

I'm running a 70mm eddy on my car.

In all honesty the tests prove that between a 65 -75mmTB no gains were actually seen from the TB itself. So get what you want.

and dont be a dick... were all in different time zones.
