a couple ??'s

[dgas]

To save space i'll just post them in one post, '

First- Are a 250 ci and 292 ci mounted a direct swap bolt for bolt in a 1966 C20 PU

Second -I was told this last weekend that a six and V8 both use the same frame mounts ,using different metal/rubber mounts, true?

Third - A freind has a five lug RE that was in a COIL sprung truck for free. He THINKS it was in a late 70's PU using lower numerically three series gears. (like 3:36 - 3:40's) W/O more info does this RE ring a bell w anyone and will it directly swap , bolt in, w the stock drive shaft for my massive 66 RE (I do NOT care if it is 3/4 legal or capable, my truck will be downgraded(UP?) to a 1/2T rating.)
