its supposed to be a 1980 80" shovel but it has 10 fins and the heads have a 66 on them, I cannot find any other numbers and my interweb search rendered no result thanks in advance
I have a cone shovel with STD cases that are marked in a similar fashion.
Thanks for your reply Eric, very good info, I will post more pics in a bitWelcome to the forum. Why do you think it’s a 1980 80”? Do you have paperwork for the engine? If so what does it say? Some engines have a state-assigned number for one reason or another but often they contain at least one letter to identify the state concerned. Often but not always.
As Andy mentioned, those are not pre-70s numbers. Your R-H case is 70 or later if H-D or it could be AM. Did you remove the paint from the front of the case and if so what did you find? Photo?
And did you look for numbers under the cases? H-D Shovel cases usually have crankcase production numbers (CPNs) under both halves for 1974 and earlier. As of 1975 models the left case still had its CPN underneath but the R-H case had it inside the gear compartment.
Also about 1975 H-D began stamping extra ID on each case. For example A123. Some left cases have it near the CPN but most have it at the back. R-H cases usually have it at the back, just inboard of the oil pump.
Anything stamped on top of the cases near the rear mounting bolts? Depending on engine model and year some H-D Shovel cases have Hs or 7s. Photo?
Some AM cases also have ID in that position. For example some STD cases have several characters there which are an abbreviated version of their main ID number. Anyway, a photo of that area would be a good idea. Close-ups of the entire both sides of your cases may also help because I can’t tell a lot from your other pictures.
I have an "H" close to the rear left case mounting bolt
Re the heads, in your other photos the 66 looks like it is near the spark plug hole and it is probably part of a casting number. Front heads had 05 66 and rear heads had 07 66. These were introduced for 1966 models and they remained in use for some time.
On top of each head on the R-H side you may find date codes indicating the month and year the heads were cast. For example 4 75 would indicate April 1975. These codes are normally near the reliefs for the pushrod tubes but may be hard to spot so look closely.
Do I see a marking on the base of your front cylinder? If so what is it? In your other pictures it looks like one cylinder has casting number 16568-66? Can you confirm please.
The other cylinder may have casting number 16587-66? If so can you confirm. And what other markings does it have? Thanks.

That L7521 number is an anti-theft number. They were used on transmissions, front ends, frames, etc.appears to be a type 4 cowpie 4 speed it reads L7521
thanks again SBT, what your saying makes total sense to me specially after you pointed out the "dash that succumbed to polishing" again thank you so much for the constructive comments regarding this motor and trannyThanks for the extra photos. Re the Hs, is one wider than the other or is it just the picture? The latest I’ve seen them on H-D Shovel cases are 1976 models. On alternator Shovels they were used for the FLH and FX etc as opposed to the FL which had 7s there.
Looks like some characters under the left case may have fallen victim to polishing? Notice the 1 has a top serif at about forty-five degrees and no serif at the base. Notice the 4 is sans serif and has an open back. The combination of these two characters makes me think the left case may be early-70s. Shovel CPNs for that period had two sections. First character (1) was a code number which your case appears to have. It indicated 74ci OHV. Next two characters indicated model year but they may be missing due to polishing? Then there was a hyphen or dash which may still be present? Second section contained four or five characters indicating sequential production and your second section may be 4++7. In your photo below do I see a hyphen/dash?
Look underneath your R-H case for that style of CPN.
If the cases turn out to be H-D then the number on top of the R-H case may have been state-assigned. Did you receive any paperwork for the engine?
Hard to be sure from your pictures but on your left case is there a number boss like my example below? A boss wasn’t required after 1969 models but it remained as part of the casting anyway for a while.
Trans isn’t a cowpie. Instead it has a ratchet lid and the lid is 59 or later because it has a switch. Yours looks like neutral indicator switch #33900-59. The lid may even be 65 or later due to the countersunk socket-heads. Is there a vent screw anywhere in the lid? As of 56 models vent screw #34720-56 was installed as per this example.
On the front of the trans is an additional original component identifying number, aka security code, aka anti-theft number. On a trans case, L indicates about a 73 or 74 model. Under the trans you should find casting number 34703 65 which was used for 65 thru about early-77.
Re the inner primary, some Harley inners can be fairly rough in places but that one looks a bit worse than usual. I can’t tell if it’s H-D or AM.

" EVERYTHING you need is just ten or so 1/4 screws away" and the puller cause I'm not using any flat heads to separate the cone from the case, if everything works out proper I'll make the puller for the ignition cover so I can pull it apart.take the cam cover off & see 100% if it has numbers stamped inside as in my picture,
if it does then it's Harley, but doesn't have factory VIN numbers, they have been removed,
& the same goes if the inner number has been removed, as only Harley stamped them there,
therefor if it is removed, then its a Harley with the VIN number removed & the inner number removed.
both ways you have a problem,
if there are no internal numbers, & NO sign that any have been removed, then it fair to say it is NOT a Harley & the numbers are legit,
I take it you don't have a title as the numbers on it should match,
belly number do not get polished away,.. they get removed to hide a motors identity,
& to me it looks like a factory VIN has been badly removed from the position the Factory stamped their numbers.
a quick removal of the cam cover will answer ALL your questions about it as the internal numbers by Harley show capacity, year made, date made & what production number for the day it was, EVERYTHING you need is just ten or so 1/4 screws away
