Hi gang.... I'm building a 75 Camaro with a 350 4Brl, putting a Comp cam CS 279T H-107 T thumper cam, 2.02-1.6 heads, Edb RPM intake, roller tip rockers... have a 750 holly for it. was wondering if I should go with a 65o instead? Going to put a 3:55 posi or maybe a 3:73. auto has shift kit. any suggestions before I break my back putting it all on? Have all the engine parts ready to go.
