Thanks for the info guys. I think he is using Rhodes lifters in it. the reason for the cam choice is money's tight and I had it lying around from a 455 that I have and gave it to him knowing he needed it more than I did. He has a code book that breaks down all the #s for every Pontiac V8 they made, it coded as a 360 horse 428 but had the windage tray and oil gaurds over the rockers. Those are HO only aren't they? It might be an assembly line goof. I hear it wasn't too uncommon for parts to get mixed up during assembly. Sorry I misspelled Tripower guys.
