I had originally wanted a 5 speed but that idea had to be scrapped for a C4 and a modified brake pedal. But, with that said, it really sounds like a fun idea - with no belly button engine such as SBC, but would rather hear that the bigger GMC (270cid?) engine was to be used.
270 and 302 GMC 6cyl's, Chevy had the 261 which is almost equivelant to the 270 GMC. I like the bigger 6's too, but he's got the 235.
