Definitely a later 70's era block. You'll be looking for one stamped C 440 HP appropriately dated. Might be a tougher find than you think.
I figured as much. The location of the E was throwing me off. But the more I thought about it, I think the guy is right, and he thinks its a 75 block
IF ( key word right now )
I buy the car , finding a correct dated block right will be a hobby,
not a necessity. Im more worried about body condition , color combination and options. Not sure I can do anything with it right now anyway.
but in all actually the 1st order of business would be make sure its dependable , then a phone call to Vintage air products .
I'm pretty well past that OE correct phase of my life. depending on the price point obviously.
I want to enjoy it and I cant tell if its a numbers engine or not driving down the road
