This Pontiac 400 came in for a stock rebuild. Some folks may not know that back in this time period Pontiac had their own engine program. This 400 has a Edelbrock Intake and Valve Covers along with a Holley 750 Carburetor for a little added performance and style. These engines produced around 300 HP in their prime but in 1978 were reduced to 180 HP. The Muscle Car era was long gone! This one should produce a little over 300 HP.
