The GMCs only came with the V6, there were no GMC V8s while they were using the V6. I have the 305 V6 and that was the smallest. Any of them out weighed a SBC by a couple hundred pounds, probably a BBC as well.

I meant to say that in the first post. In the GMC shop manual for 65-66 they refer to a color code for the springs. Mine took purple, but I can't find a legend remark as to what any of the colors meant. They had 4 or 5 colors.

Anyway, thanks for the help.
