need help figuring out how to id a 429
i was wondering if anyone knew how i could id my 429. it came off of a 1970 ranchero squire but not sure if it's a regular 429, a cobra jet or super cobra jet. The numbers on the block id plate read: 429 70 6 and on the bottom line 9-J K821-AC. On the intake manifold it reads: 4 DOVE-9425-B (or E? not too clear) F4 9H28. thanks.
