I raced with a guy who had a .080 over 350,it had 425 caddy pistons i beleive and it really ran hot,not sure if it was not jetted/timed right but it lasted a while.

I wouldn't run over .060" unless it was sonic checked. .060" is usually ok on older blocks without massive core shift. .060" on a newer casting is just asking for it.

My advice... start building another short block as a spare.

I had an engine that ran strong. Found it was about 70 over.
RAZ if you go 60 over on some of the new blocks you end up with a Great spot to tie the rope for the boat to........Makes a good anchor for a boat up to 35 feet long.

This one will sure raise a ruckus..........

We pieced together a motor off parts laying around. 4.125 JE pistons in a 1/2 rocked 350 block. Ran it about 15 shows with no problems other than it running about 230.

For the builder, driver or engine???

Block fill 1/2 way up would work too. Just don't try and run any endurance races and give it a bit more clearance than normal.
