Do a search for third generation camaro and the top site has a ton of information on the early chevy tbi injection and the members there probably have more experience with them than anyone, anywhere and they'll be able to steer you right

The stock TBI on a 350 flows 420 CFM, but the breather only flows 330CFM. After the ultimate TBI mods, the TBI should flow around 520CFM, and with an open element breather you should be able to take advantage of all that extra air.

Your high performance 'airflow' parts source for GM / Chevy Tbi / Vortec / Marine + Racing check this site, these guys will sell you a ported throttle body at 620 CFM that'll really help..then throw some heads and get a chip flashed to match and you'll have a runner
