Is .060 over to much for a 350?

I've had a good many 010 blocks bored .060 & never had a momments trouble, but I'd never go .080 over :shock: , IMO> thats just asking for it.
Bottom line, have it thoroughly checked out by a competent machine shop.

i had a 350 block bored to 4.125 because we had all the other parts laying around and needed a motor asap. we filled the bottom 1/2 with block filler. It ran a little warm I'd come in after a 15 lap feature @ 250*. This is in a imca modified, i turned it 7500, ran it about 10 races to finish out the season.

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.
