It is nothing special. Chevy 250 ci, circle track head with recessed head bolts,and dividers removed, with 350 chevy valves, screw in studs and roller rockers. It has a crane cam, (forget the specs) offenhouser 4 barrel intake, holley 390. Split exhaust manifold and true dual exhaust. HEI distributor. Nothing really different. We had purchased everything to go to a sbc 4 speed, but change our minds.
