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.

You have NOTHING to worry about @ +.060 on a 350 Block,thats Only 4.060.A Stock 400 is 4.125.
Must have Ran a Couple DOZEN back in the 70's @ +.060!!!Never had a Problem,Until the 400 JUNK Came along,...............>
You say its a Stroker,....?How much Stroke do you have?

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:
