Six bolt pattern valve cover cast-in pedestal and revised ports. Crankshaft may have to be upgraded or modified for stick at extra cost. In this process, the 400 had a much hotter exhaust temperature than the 383; the lower compression motors allegedly had higher heat rejection, which helped cook the emissions. So that is really getting with the program for an engine combination that should be easy to maintain. To complement the big roller cam, we selected a set of 1. The carburetor would draw the crankcase vapors in, burning them to painlessly eliminate a source of pollution.
