Small block strength

I had a 360 with a casting date of 6/18/70. We bored it .100 over and it never ran hot. But we were just going on being told that they were "under bored 340's". LOL. That was '89 or '90. Last I heard it was still running in a buddys Cordoba in the city. The pistons cost $800 back then! Arias I believe.
I spent 4 hrs trying to convince him they made a '70 360. Don't think he ever really believed us. 10.5 to 1 compression flat tops. The first short skirt piston I had ever seen.
