Re: 73 Big Block questions

re big block questions joe lucia in addition to the information provided by bob patton i will offer the following first in addition to the ' caprice block also being correct for the ' corvette the caprice heads and intake manifold should also be correct if they are the caprice's original ones intake should be casting number heads should be casting number with respect to the stamped number i can't be of much help if you are reading the number correctly it wouldn't appear to be a gm type stamping bear in mind that sometimes automotive rebuilders will stamp their own codes into engines that they rebuild
