I have a good running used engine that I put heads intake and Mallory in it. Has rebuilt fuel pump new suppression cloth wires. The Mallory has been converted to electronic ignition. It has a weiand intake and offy heads. The heads were in really good shape. I was going to use this in a car I’m building but decided to go another way. Has new gaskets there is a little wear in cylinders should not have any issues. It was rebuilt sometime in its life. It is a 49-53 8rt
