Yes, I have a 65 413 that has the bosses, but not drilled. Have a later 400 block with the bosses already drilled. And of course, my 440 has neither. :-(
Haven't decide what I will do yet, but definitely using the 440 in the Cuda. I have the BB K-member, which does me no good. Has anyone ever duplicated the mount from the original A-body 440 cars? (M-codes)
