Currently have the stock 56mm throttle body on my 95 302. Upgrades in consideration of airflow is a BBK cold air intake, BBK headers, and aftermarket exhaust and mufflers (not positive about the brand, definitely aftermarket with better than stock airflow though). I have a 70mm throttle body laying around, and was wondering if it would be a good idea to throw it on and try it. The car seems to rev pretty slowly from 1000-3000rpm, so i am hoping to find a bit more responsiveness in that area. No internal engine upgrades, thanks.
