425 Cam bank angle
I have a 425 Oldsmobile and am trying to figure out what cam bank angle I have whether its a 39 degree or a 45 degree. Can anyone tell me a 100% sure way to figure this out? Also is there anyway of telling if the heads on the engine are the origional heads that came on the engine. Here is some of my eng info.
Block casting 389244D
Heads Casting B 389395
Lifter diameter is .842
