396 375 L78 Casting numbers

Hi! I have a 272 L78 block that I'm rebuilding. It's been decked off so their is no date stamp on the pad. I'm looking for a set of matching 840 heads that would be right for the block. What would be a good date for heads to match block? Thanks!

What is the casting date of the block? It should be cast into the passenger side of it?

Experience...... It's what you get when you didn't get what you wanted.

Re: 396 375 L78 Casting numbers

Find a set of 840 heads that are close to 12 20 68 (Dec. 20, 1968). I'd think you'd want a set dated within a week of of the 20th. You'll need a 163 intake, too. The date is cast into the bottom of those, so it won't be seen once installed. Beware that GM was still making the 163 intake a few years ago (maybe they still are). The newer ones look differently than the original ones from 69.

I see you are in Louisville. I'll be there later this week one day for the Farm Machinery Show. Not looking forward to the crowd, though. Take care, Lee.

It's a 4 bolt main. I'm also looking for a 69 70 8 inch timing chain cover. It should have dowel pin holes with AOR on the timming tab.
