Found what I think is a Y block sitting in a scrap metal pile. Flatheads, I'm pretty well versed in (& there's also what looks like an 8BA on the property too). These, not so much. Is there an easy way to ID if it's a 239, 292, 312, etc. from the outside? Looks like it's pretty complete w/ exhaust manifolds, intake, carb, etc. Thinking of making him an offer (He ignored my offer on his '49-'52 Ford truck) if it might be one of the bigger ones. It was stored inside until a couple weeks ago. I never knew it was there, & I'm driving by there almost daily. Must have been in the barn for 40 years, or more. I don't think the guy has interest in this stuff, as it belonged to a family member who has passed. What's a reasonable offer, & what should I look for?
