Well I scrounged up the block casting numbers and found it to be 3738307 which reads as below. Now I can play the parts game and get the correct gaskets and pushrods not that I think they differ that much. Is there any way to tell other than removing the side cover to see if the engine is solid lifters or hydraulic?
