stock block? 60 over is pretty thin.......crack in the cylinder wall?

check the plugs to see if you have one that is really wet :wink:

Could have gotten into water passage, when clearing the block for bigger stroke crank.

the only way i seen anyone get lucky with a 60 over block and not have the block cracking or running hot issues is when they used the HD chevy nickle block...... other then that i myself would only use a 60 std block for an everyday... go to work and home.... driver only :wink: 60 is just a waste of money in my honest opinion :roll:

aint nothing wrong with a 60 over 350. built many of them and run quite a few hard at the track. never had a minutes problem.
