[CamarosRus]

Here's what Ive concluded after seeing Chevrolet/GM literature and contacting other
70' Camaro enthusiasts.

There was NO Camaro eng/trans combo that would have come with a 3:55 COW non posi rearend

ALL 70' L-34's came with 3:31 (Nothing Optional)

70 Z-28 was Std with 3:73 Optional 4:10 Posi was MANDATORY

70 L-78 was Std with 3:55 Optional 4:10 Posi was MANDATORY

70 L-48 4 spd Std was 3:31 Auto was 3:07

I am not listing the L-65 and 6 cyl ratios
