Don't go by here say as we sonic test all the blocks tha come through our shop and to tell you the truth we find more of the older blocks with inconsistant cylinder wall thickness, We have about 45 of the older blocks in the shop that we only rate under 400 horse do to poor cylinder wall thickness.

The later blocks seem to be more consistant as far as cylinder wall thickness as we have machined quit a few of them for our shop and other shops accross the U.S.

If everybody went by here say everything would be junk.
