Original 1969 Corvette 427 BBC and Matching Number Heads Long Block

I have an original 1969 Corvette 427 Chevy Big Block with matching numbers 427 BBC 435hp heads. The block is an original 4-bolt main and has been cleaned, checked, magnafluxed, .040 overbore 4.290, and lined honed and is ready to be assembled to drop in and go. The block and heads have both been painted with aluminum engine paint as well. I had originally assembled this to go in my pro street nova. This block has 0 Miles on it since I have bought it and is in great condition. I do have pictures of the block and heads assembled and disassembled. Please only serious inquires these are very rare parts and are collectors items. I am located in Cincinnati, OH so this would be a local pick up only. NO TRADES. This is for the long block with internals:

-Forged gm steel crank,

I just bought a 69 vette with a 427 / 435 hp.  It's an early production and I am unable to find the block numbers location other than the Suffix code.  From what I've read so far the other numbers are on the driver's side pan rail.  Where the heck is that?
Thanks to anyone that can help.
