Default Is .060 over to much for a 350?

There is a 350 rotating assembly on CL and was wondering is .060 over is to much for the 350 block? Thought about getting it!!

Probably depends on the casting. I know of many people that have bored a 350 .060 over with no issues...Only way to know 100% is to have the block sonic tested..I believe the 010 block is one of the better castings.

I wouldn't be afraid to try it...but It's easy for me to say that when it's your money.

HAHA yea I bet it is and I haven't got a block yet this is just the rotating assem. I can get blocks for $100 dollars a piece!!! So not that high only thing is the rotating assem. 350 bucks not that bad but I think I'd rather spend the extra money on a new one and get .030 over pistons!!! Just gonna see what yall thought!!

At .060 over on a 350 block I would sonic test first as we have not seen many blocks that would make .060 over and be used in a performance application.

We had a customer bring in a block and it sonic tested .120 on the thrust side and he said the core shift was good but I said its not a very good indicatior.

At .060 make sure its plate honed as well.

The 350 has the broadest piston offering of any engine.
SRP offers dome pistions in +.020, +.030, +.040, +.060.
Flat tops are offered in +.020, +.030, +.035, +.040, +.060, +.070.
Rule of thumb - bore the block to the smallest diameter to keep the wall thickness at a maxium.

We take them .060 all the time, we even go .080 on a lot of race engines with out any issues.

I was surprised at this because I here of guys going .060 over quite often...but to the OP I would trust this guy's advice over most anyone in regards to engine block machining .
