1969 Chevrolet Big Block 427/454 #3963512 Engine Block

[mnow987]

I need some help finding out any more information on this block. Here is what i've gathered so far.

• Casting Number: 3963512
• Casting Date: May 26, 1969 (E269)
• Assembly Date: July 9, 1969 (T079 stamping)
• Markings: Includes "HI P R Pass," "5T," and "F7" casting marks
• Main Caps: 4-bolt
• Applications: Suitable for 427 or 454 high-performance builds. Correct for 1969 Chevrolet vehicles, including Corvette, Camaro, Chevelle, and El Camino.

Can anyone tell me anything more, how much these are worth, or if there is any other markings i should be looking for? Cannot find a partial Vin on any numbers on the deck. Good core for rebuild, no cracks or repairs observed, ready for machining.
