This is the initial run of my 300 six build. It's got a Clifford intake, 500 cfm Edelbrock 4 barrel, Crane 901 torque cam, split EFI manifolds, Cloyes adjustable timing set in advanced position, 9.0:1 compression with ~.038 quench, mild port, smoothed chambers with clearance around exhaust valve and all necessary machine work. Should be approaching 400 lb ft torque.
