Picked up a Mexican Block today!!!

Yeah Its a 1971. Any way's out of curiousity How much can you bore them over? Right now its a standard bore. I am Building a 331 using this block but if for some reason something happen's would .060 over be to much?

I think the walls would be a little thin & would run alot hotter than normal but I would have it sonic checked before boring out that large honestly.

More Fuel PePe

Congrats on the find

Safer to go .030 over, i really doubt you'll see much more power by going .060 over.

Yeah I am going .030 over because I already have the pistons but I'm just sayin that if I blew a piston or somethin like that would I be able to go more than 4.030

Anyways i'm shooting for 10's N/A then possibly a 100 shot of nitrous.

I know a guy who bored his .40 over. it's like a 352. I was like 352? WTF? but he told me he had a mexican block and it can go more than .30 over.
