Hi, I am new to the group but have been lurking for quite a while. I just bought a 64 Daytona Hardtop project, it is a major project. It has a Stude V8 which the seller said was an R1, but I doubt it. I checked the machined pad at the front of the block and it was blank. Is there any way to tell what engine this is based on the casting numbers? The block casting number is 554641; the head casting number is 1555294. I checked in my recently purchased parts catalog and those numbers do not show up as part numbers. Can anyone help? Thanks,
