Re: 1968 Chevrolet CST Survivior.

My guess is that is Not a 305 block at all.

Its diffidently got a nice set of early camel hump Hi perf Fuelie heads off a 327 . (Get the cast number off the back of the block).

Quote:
Large “camel humps” cast # 291, 461, 461X, 462 Original hi-perf or “fuelie” heads; chamber sizes are 62-64cc; both 1.94/1.50 & 2.02/1.60 valve versions available; 291 on 327’s thr ‘68; 291 have temp sender hole; 462 don't
Its got a Early intake manifold but that quadrajet is a late 70's early 80's carb , and its a good year quadrajet. Good Carb

You have a nice motor there . Change the oil

That might be the original 68 327 motor and its got hi perf heads. Maybe factory original on the CST
