The car is an unmolested all original configuration convt with standard 400 CI engine, pontiac Safe T Track, automatic trans three speed turbo 400, original rebuilt 4bbl Quadrajet. I don't know the gear ratio as I am not that much of an expert but I do know that it is all stock and has never been touched. The engine had a .30 overbore and I have since rebuilt it. The orginal heads have been rebuilt with three angle valve job, new valves and hardened seats. I am using the original reconditioned exhaust manifolds and intake manifold as I am trying to keep everything original.
