273 w/ offenhauser 4 barrel intake & 904 PB

I bought the car from a guy I know. I keep tabs on all the local A body guys. When tje car went up for sale is when I became interested I had no interest in the car when the engine was being rebuilt I know it was pulled completely down hot tanked magna fluxed new cam, stock crank, pistons and rings not sure what was done to the heads the previous owner had the car for many years he bought it in 1968 and and after driving it back then storing it this long he started to restore it 2 years ago and decided to buy a finishef 1940's chevy rat rod pick up instead.
