I am preparing to start a build on a 496 BBC and need some suggestions to come up with the best possible engine combination (cam, heads & C.R). My car is a 67 Chevelle with a 4:10 rear end gear and a 4 speed manual transmission, no power brakes. This car is street driven but only as a weekend warrior. I have a set of GM open chamber square port heads with a matching factory intake. I would like to use these parts but have heard many negatives about using the square ports. I don’t have any issues running racing fuel or changing the rear end gear but would like the engine to appear stock with the exception of headers. Any suggestion would be of great help.
