Re: 360 Valve train tick/tap....what now?
carefully move a rod or shortened brook stick around the valve covers and see if you can stick it to your ear and narrow down where the knock is.
Ive had a 360 ram a pushrod THRU a rocker arm, and it ticked pretty good, it was a noticable difference in power though since that cylinder was no longer contributing.
pull the valve covers and check for loose arms, bent push rods, keep them all in the same place they come from, they wear in patterns.
they are cheap to replace as components if you need to, its the same pushrods as a small block chevy.
use plenty of assembly lube when you reinstall, and torque them to spec. they arent adjustable, you torque to spec and thats it.
if it isnt a rocker arm or pushrod, its a stuck/collapsed lifter, and thats a bit more complicated to remove and replace, BUT possibly could be fixed with an oil addititive.
