The crate motors came to us dressed as a production truck motor we pulled off the breadbox intake, distributor, exhaust manifolds, truck oil pans, timing chain cover, gear sets, oil pump and pickup, camshaft and lifters, and cylinder heads. Nothing else was removed from the short block. The cylinder heads got a 3 angle valve job, a new camshaft and lifters installed and degreed in a fuel pump eccentric was added ( magnum cams don’t accept pump eccentric ) a double roller timing set, an early style timing cover, car type oil pan and pickup, the heads and new gaskets installed, an M1 single 4 barrel intake, and a Mopar performance vacuum advance distributor.
