Has anyone ever heard of a 512 small block. I came across this one today. Part# 3959512 with a date of E 9 9. I'm assuming that this must be a replacement block but for what??? Any value??? Thanks

I've seen a few 512 SB's.

They made 100's of thousands 010 blocks.

I have one of those 512 blocks that has been built into an alcohol injected drag engine for my '91 Camaro. It's circa 1963 and had much beefier webbing than other 327 blocks that my builder has seen. I had another 327cu block out of a 1966 C20 that didn't hold a candle to the amount of material in the 512 block.

What's yours look like compared to another 327?
