Thanks guys.....what about thickness of finished bores in the early 265/283 blocks? Any ideas on this and how it compares to best 350 situation? Isn't there a small-bore Bowtie block available with an unfinished bore size of about 3.7" so you can bore/hone to the desired size instead of sleeving down for the smaller displacement racers? Bub, is that sleeve/cracking problem more common in the larger or smaller bore production blocks or ALL of them? Thanks again!
