Don't smack it with a hammer just yet - try a magnet!

You don't have to smack it,just tap it firmly.
I actually cracked off an epoxied one that a magnet did stick to.
Turns out the forger added fine metal shavings to the epoxy.

Re: 70 Z28 Engine Block Casting Numbers
 

As I recall the 3970010 casting # was used for a large variety of applications and years. Someone will need to check this but I think that casting # applied to 2 and 4 bolt mains and ranged from the late 60's thru the late 70's.

Re: 70 Z28 Engine Block Casting Numbers
 

The 010 block has many different applications in both 2 & 4 bolt configurations, and are fairly plentiful. I think the block started in '69, might be '68 - but I'm pretty sure it's '69+. The casting numbers are generally pretty straight, not sure I've ever seen them crooked like that.
