I bought several engines out of an old shop this week, 2 of them are Y blocks and since it was an old ranch with all old trucks setting around, my first assumption is they are truck/pickup engines. The one is pretty obviously truck. It has Holley 4 bbl and the big pressed on double groove water pump pulley with windows. A couple questions on that, is the intake pretty much the same as the 57 car square bore? And how do I tell if it has the forged crank?
 I'm still digging around on the engine I think is pickup. It is a 2 bbl. Holley with the same red paper element air cleaner that my 59 pickup has. I haven't found the numbers yet, it was getting dark when I was scraping around but the block is kind of a light green and I can't find anything on the internet an green Y blocks, other than it might have been a reaman. Comments? It has a spin on oil filter. Also, do you have to cut away the exhaust gasket to find the head number?
Both engines have the exhaust cross over.
Thanks
