did you have your gt40s ported or not? and did you have any other mods? or just the gt40s and the e cam?

ya they sound nice but for an almost stock 302 wouldnt that be overkill?
what im planning on is getting some gt40 heads a cam either ots or custom made, an explorer intake, and throttle body, I have a cai which i know doesnt do much, and an off road h pipe and im getting some shorty headers and a c&l 76mm mass airflow sensor. i know that wont put me up to my mark but when i get all this installed and tuned ill go from there to see how i like it there
what do you guys think?

Yep first sentence says it all
(Complete Head (64cc Chamber) For use on 289/302/351 Windsor-style engines Improved air flow over original GT-40 aluminum heads)

Head being the key word.

I ahve them and they work great but i got them dirt cheap, not worth $1100 +

For 350 at the tire you're going to need more displacement than 302/306 even with the best of heads and aggressive cam...331/347 with a good aluminum head and well matched cam/intake will get you there quite easily. The GT40 alum heads are decent enough but nearly the same performance ball park ask the AFR/TW/canton/Eddy heads.

alright thanks for your help because i would have baught only one head and now known lol. I'm still curious about vtecwhos set up whether the numbers he made were with just the regular gt40 heads and an e cam or if he had the rest of his set up then

bump? Also im going to do a compression test in a couple days, each cylinder should be at 150 psi right? or higher. lower?

More important for them to all be close in pressure at least 130, I got the gt40x no complaintes yet, but i got for just under a grand from blue oval, that and i wanted to keep stock compression with my kb

alright thanks. I'm still curious about vtecwho's set up if he made his power with just the e cam and heads.

Yep the engine that I just pulled out I am going to do a complete overhaul, slap on some 64cc X heads with a Crane 2030 cam and a Kenne Bell. Still looking for that Notch to put it in, but it should be a good performing little package.
