Can anyone identify this cam?

Yes, to say the least. The Victor 340 has it’s own place, and this build is about as far from a happy place for one as you can find. You can sell that Victor intake and double pumper here to help offset the cost of the transmission and converter work. A factory high stall converter (precision of new Hampton, Hemi specification converter) would be fine in this combination. The existing cam, 600 Holley, performer rpm, and a performance distributor recurve will meet your goals very well.
