Stop in for a cup of coffee

I had a similar issue with my numbers 383 for the GTS. 2 pistons locked solid. But obviously i need to save the block. Same as you, I rolled the crank out of it (barely). Then I had to pound the locked pistons out from the backside with a 2in Iron pipe and a sledgehammer. Was able to bore the block .030 over.....
I'm not so worried about the numbers matching factor so much, it's a 318 duster but the problem is I bought the good block as a bare block for 20 bucks so I need the parts from the locked engine to build the block otherwise I might have just tossed the locked long block.

I'm still debating if I should keep or toss the numbers 318. One cylinder is gone and I doubt 30,40 or even 60 over will clean it up.
