Selling this Running 455,  what’s a good asking price? Just trying to make room in my shop. Feedback appreciated.

The easy answer is whatever someone is willing to pay. That said, assuming this engine is original and not cobbled together, it appears to be out of a large B-body Pontiac with #15 heads (1.96 intake and 1.66 exhaust valves). So it is a valuable core 455 engine. So $500-$1000. I'd start by asking $700-750 and see if you get any takers.

YH indicates this is a large car with an automatic transmission - 360HP 10.00 CR. 1970 is the only year that the 455 was 10.00 or 10.25:1 (considered high compression) - after that compression dropped to from 7.6-8.4:1  for all 455s built after 1970.
