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!!

Only if its buildable, if not, your pretty much done if it needs boring or you can get 8 sleeves put in...lol

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. :D

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 .
