If my eyes haven’t deceived me, it has .20 oversized pistons.
I saw what looked like an “A” turned 90 deg at the top of my photo. Is that why you think it might have .020 oversize pistons?
 
I completely missed the A. I guess because you were not asking about that. @440 4 speed seems to be correct there.
 
Thanks so much. Knowledge is power, I already feel like I can do better burnouts!
 
I forgot the diamond stamp. I believe it is for oversized tappets
 
I've torn down a few engines with the sideways A... Haven't found a single one with oversized pistons... I think sometimes the guys in the engine assembly plant got bored & stamped pads for fun...

Wonder it that happens more on the 2nd shift???
 
Probably not as much anymore since drug testing has become so prevalent
True, but would be an interesting study to see which shift had the most variations on the engine blocks.
