Ok, '68 3000 gas motor - dropped #3 exh valve and punched a hole in the piston.
Checking the bores I've got a .002-.004" ridge a little more than 1" down the cyl.
The manual specs 4.2007"-4.2032" and I've measured a max on #3 at 4.217" at their "W" measurement 2&3/4" down the bore.
The other cyls are at 4.205 and 4.206"
Do I re-hone and put a stock piston back in with new rings or do I take the block to the shop and go with .020" oversize pistons?
Opinions?
