Thank you Neal for the helpful information! Appreciate it
Rickey was more than likely the customers name the marking 4.7 doesn't equate to anything I can think of. My suspicion based on the bronze lifter bushings and evidence of a gear drive it was once a Busch GN engine. Based on the bore size it would have originally had a 3.625" stroke. Since you have a caliper take a depth measurement off the piston to determine the stroke length.
As far as gasket go the Felpro 1026 head gasket works well for most applications you'll need to run a 1200 gasket for the intake based on the head port size. Studs or bolts is your preference, you should be able to order them from ARP. Be sure to use a good thread sealer on the threads into the block as 8 of the 14 fasteners go into the water jacket.
