I have a 1970 Pontiac 350 (YU block, casting code 9799916) with 1968 2bbl heads (17) that came in my 67 400. Originally from an A-body car. I have a YT long block (67 400 w/ 670 heads) to build to replace it, and am wondering about what I can expect to get for the 350 if I sell it. It has an Edlebrock intake and carb on it (I think the Performer series) - I may or may not sell the carb and intake with it, depending. Any ideas?
