Y Block Help Needed

[Hot Rod Reverend]

Don't know if this has been covered yet but a quick way to check out that cam would be to remove both valve covers, start the engine and watch both banks as the valves operate. It should not take too long to notice anything out of whack (like an intake valve not moving up and down, etc). The only thing that would be hard to check here would be the actual timing of the intake/exhaust event as it relates to the rest of the cylinders...

Anyone have an old Sun Machine he could borrow?
