My .060 over bored 340 ran just fine until i sucked an intake valve. (my fault:violent1:) and it went thru the cyl wall.
It like to run hot and i fugured out why. major core shift!!!!!
When you shim your valve springs.........Make sure you seat the lock!!!!!:sad1:
That stunt cost me a block, piston, rod, and a cyliner head!
The 318 isn't a poly block is it?
