Gentlemen, please help me identify these cases.
The left one doesn't have radial fins/enforcements for some reason. There is a DMV number instead of the original one, however, it doesn't show up at all on DMV radar. There is also another number to the right with some eagle logos around it.
The stroke is approx. 4.3", the rods are S&S, and the flywheels have "Sumpter spl." stamped on.
Is that an aftermarket?
Some factory re-manufacture?

 

That is indeed a DMV stamped number. Could have been tied into a frame with a Kali 'blue tag' more commonly known as a 'special construction' vehicle.

Numbers to the right with the logo I think might be 'Cal Products' cases from the mid 70s to the e80s? Definitely aftermarket

Have you checked the lower belly number on the right case? If it is HD there should be something there.

 

No there is nothing there stamped, except "91"
So both cases are aftermarket then.
I guess it's not worth keeping (not for 1.5K at least)

 

both cases are aftermarket.Got any paperwork to go with these cases?

 

No paperwork - just a bill of sale. Not a big problem I guess if it goes into a modern frame w a title. This being said, if I keep them, that would be the only use - you wouldn't build a real pan with them

 

So if I keep the cases, given that the stroke is 4.25 - 4.3 (difficult to measure exactly), I suppose I cannot use standard pan pistons - correct?

 

If they have DMV #s I don't see why they can't be used.they are not
Cal Products which only made the sprocket side anyway.You can run pan pistons but I would check out how your cases are bored but you can run any bore you want if they fit the studs.

 

I meant pan pistons would be to high - wouldn't they hit the valves?
