75mm Throttle Body?

it probably would work but if you want to make more power with the throttle body it is much smarter to get a performance intake. this is because a stock intake unit wouldn't match up great with only a throttle body vise-versa.

alright well im a little short on money and dont have the cash for a new intake manifold right now. any suggestions? 70mm?

75mm is too big for any stock intake or setup. You need to be in the 450hp+ at the crank range to warrant a 75mm.

Stick with a 65mm until 350hp, or go with 70mm between the 350-450 target range depending on your set up. This has all been verified via drag race testing through MMFF.

It would work with the cold air but not the stock intake. A 70mm seems to be the size limit for a stock intake due to how much it has to be ported for it to fit. But even then the wheezing stock intake itself is the restriction, whether it's a 65mm, 70mm, or 75mm.

Hey just wondering if the 75mm throttle body works with the stock intake manifold and the BBK fenderwell cold air intake..?

You can make it work by porting the inlet of the upper intake to the same 75mm diameter. That's what I did when I bought my Summit Racing 75mm TB and it works fine.
A 75mm TB isn't too big. It's just more than you need at the moment but it does give you room to grow as you add more mods. If you decide later on to build a 331 or 347 stroker, you'll already have the correct size TB so you won't need to buy another one.
