Hey i'm looking to replace my stock 48mm throttle body with a 52 mm one cause i heard you cant run a 58mm one without huge mods,basically too much air for not enough motor, but its a 350 with a bunch of bolt ons., So who makes the best throttle body, i was gonna choose Holley, heard bbk sucks, any others good, why do Mustangs get to go to 60mm and larger without problems and i wont make any more power with a 58mm unless its a stroker motor or something?

I have heard good and bad things about them both.....

Mustang only have one big hole on TPI there are two holes. Area Mustang 30*30*3,14=2826 sq.mm, area TPI 2*26*26*3,14=4245 sq.mm
