Unfortunately the second picture you sent of the SN doesn’t help me. I'd like an extremely clear close-up of the entire SN but maybe you’ll be able to provide that when you get the smart phone.
Do you mean your engine does not have the cap screw shown below? It’s mentioned in Shop Dope 330 that I posted above. If you don’t have this cap screw then your R-H case is early-52 or earlier.need help 2002 wrote: ↑Fri Dec 25, 2020 9:49 pm New discovery,,,, on some 52 pans i have noticed a large screw just in the front of the rear lifter, a large screw like the ones on the oil pump,,,,my engine does NOT have that screw.
As for your left case, it may be a different story and the BNs may help with that. But for now, does the area around the front bolt look like this?
Or does it look like the next example, with less material and the bolt hole not extending so far out?
