Cam is now chewed and lifter is dead, do I have to pull the engine for a cam replacement or do I just remove the radiator and condensers.
Uh, reading between the lines you are considering just replacing the cam & lifters
and leaving the rest of the engine as-is? Thanks to the all the ultra-hard debris
from the chewed cam & lifter, every single bearing & bearing surface should be considered
bad until proven otherwise.
You have suffered a worst-case FOD event. (Foreign Object Damage) If you have
an emotional attachment to this motor (think muscle car owners who want to keep
their ride 'numbers-matching') ...this engine could be overhauled and reinstalled, but
if you want to just keep the truck going it may be a lot easier to swap in a suitable
replacement.
Sorry about having to share such bad news. My 2¢ worth...
