Any input on weather you guys think my setup would benifit with a 58mm TB vs a 52mm? The basic jist of my setup is a 350LT1, heads, cam, 1 3/4" AS&M headers w/3 1/2" exhaust (cutout at the track), S-trim pushing 6psi with a 75 shot of spray, and of course a 52mm TB. Just wondering if I should switch to a 58mm or if it's not worth the trouble or money. Thanks.

with your heads/ cam setup alone i would have gone with a 58 mm tb. Its worth it.... The difference in price between a bbk 52 mm and 58 is exactly the same, and you can take your intake to any respectable machine shop and have bored enlargened for the 58 mm TB bores. Just my 02.

 

Actually, the 52 went on well before the heads, charger and spray. Now i'm thinking maybe I should go with a 58mm. I can do the port work myself too. Was just wondering if I would see a benifit between the two or if I should just stay with what I have. Any other opinions out there? Thanks.
