Can I get help identifying this small block Chevy

[61-63]

Last week I acquired a claimed to be 383 long block as part of a project car deal. Even though I've been on this site for years this is the first Chevy engine I've owned in sixty years. On the distributor pad I see 3970010 and a casting date F16 I think - the F16 aren't that clear. On the side of the block is 871386 and 83 N. On the oil pan rail there is the letter J repeatedly and then 2492 at one point. At the ear is 509H4 and then 010 and 020 one above the other. This is supposed to be a 350 with a 383 stroker kit in it. The heads on it are Procomp I believe and up near the valve cover rail on both are pc3003 cnc 2011 11 01 and then 1608 on one and 0998 on the other and then 59 coeg. Can anyone tell me what I have here?

Oh, and this is a 4 bolt main block.

3970010 is a 350 cu.in. block produced from 1969 to 1980.

What is the Engine Suffix Code on the Pad?

The block is definitely a 350, none of this has anything to do with if it's a 383 or not. You have to identify the crank

Thanks for the replies. I will get the pad suffix code and crankshaft casting number and come back. I assume by pad you mean the distributor pad?
I don't remember a code but will look?

If it's a 400 crank, which were externally balanced, it will need a 400 balancer and flywheel/flexplate. That may have come with it?

He means the pad in front of the passenger side head, stamping with numbers and letters on the engine block pad

MOPAR guy aren't you!! Pad by distributor is a BB Mopar thing. Got any Mopar stuff to unload?

You can identify the crank by the shape of the flange, all cranks have an unique shape. Now aftermarket may be a different story

Thanks for the picture of the butt end of chevy cranks. The crank in this engine does appear to be a 400 crank.
