I just want to know if a 75mm throttle body will work with a stock intake anyone know?

it would take a ton of porting and will not offer any increase in horsepower

i agree, way too big for stock.

after thinking about it for a sec you can't hone it out enough..even the 65mm you have to hone some

so a 70mm wont even add more power with a stock intake

biggest i'd do without heads/cam/intake would be 65mm.

a 65mm is about all you want

im rebuiling a new engine for my car now and getting it .30 over with a ford racing e303 cam and stock fully rebuilt heads and stock upper and lower intake (dont have enough money for new stuff) and get better intake and heads in thefutureso just go with a 65mm for that or 70?

Save up for a better intake...if you are going with a new bottom end, do it the justice it deserves with a good intake.

If $$ is an issue, I heard of a lot of guys on here going with an Explorer intake. I imagine that it is pretty cheap from a junkyard...check out some other forums for "Explorer Intake"
