I bought a 59ab engine from a friend(who has severe memory loss). it was O'hauld he does not know who did it. It came w/Offenhauser alum 425 heads which have had relief grinding ( addressing the valves air flow??) the valves measure .700'' across. the valve lift is .400''. I have not identified the cam.iIt has a 3 5/16 bore,4.0 stroke. It came w/ a Fenton ,2 carb and a Edelbrock 3 carb intake manifolds.The ports on both are polished.also the block intake ports are polished. Has adj valve lifters.The center coolant port on top of the block has been sealed w/ a soft blue material ?? the 2 fenton exhaust headers have been relieved (polished?)The eng came w/a41'PU project. Projected performance??What do I have?????? 'thanks"
