Did 985RWHP on a short filled, aluminum capped and girdled destroked 440 turbo'd 388 cube. Mains looked like new after a year of beating on it.
Then I wised up bought a KB block and made more power on less boost with some more cubes.
Thanks for the info

didn't all the cylinder splitting happen recently with the long stroke cranks and short skirt pistons loading the cylinder walls or do they also split with stock stroke cranks? 
I have seen several 400 blocks with 3.75 strokers split the cylinders with 6.76 long rods. My 1976 400 block with 6.8 long rods and a 4.300 stroker hasn't split one yet, thinness spot sonic testing in any of the cylinders was .163, thickess was .230 after boring  I have seen thinner and thicker stock blocks  As already said you have to test a bunch of them to find a really good one, that is the reason I bought one of the new World wedge blocks at 4.500 bore  I have sonic tested it on the thrust sides,it is siamese bore, and the thinness I found was .300  That rascal is heavy though

My block supposedly has been sonic checked and was in a naturally aspirated 505 alky digger.
It's .030 over so I was going to take it .060 and hope for the best, but I'd really like to come across a deal on an aftermarket block.
Thanks for the info.
do you have to take it to .060 or will it cleanup at .040?[keeping cylinder wall as thick as can be.]as $$ permits i would like to find a better block also a KP440 or KB aluminum.
