Stick with a 65tb. You'll have better low end torque and better drivability.
IMO alot of people are running bigger tb's than they need. Maybe it's bragging rights or something.
The 65 will support up to 300-350hp easily. Just as you can over-carb an engine, you can overwhelm it with too large a throttle body.

yea i guess i'll go with a 65 tb and what a 70 maf? or 75?

The first mod I did was a 76mm C&L pipe and K&N panel filter along with silencer delete. (Bumped up timimg also). WOW! what a difference. Felt like 20-25hp by "seat of pants" dyno.
So yeah, I don't think 75-76mm pipe is to big. I drove mine like that for 4 months till funds came around for H/C/I.
Good luck.

IMO i think so, i have just read some ****, and i think like 80mm will not pass emissions, so its illegal in some states, and i guess for racing pruposes

well i picked up a 75mm tb for real cheap thats why i was asking, and no emissions for me as far as the mass air goes.
