Crane dual energizer camshaft which was under .480Lift I believe been Ran in mud truck until last year started to feel like it was getting tired. I built different engine looking to get rid of this one. Be a good start for a solid old school engine build. Drag race, bogger, rat rod, mud truck. Had upgraded valve springs spun and made good power until it started getting tired. I estimated it around 250hp and always did better then I thought it should for no more then was done too it. Update just checked and this Is a 4 bolt main engine! Sure like this engine gone, lots of maybes and no $$$ in hand - SOLD
