1952 Panhead Shifter Cam/Drum Differences

What is the correct shifter cam/drum for use on a footshift 1952 Big Twin Panhead 4 speed ? Is it the #34008-52 or the 34008-52A. And……What makes the two different.

I received only one reply over at the AMCA forum via email on these questions. The response said the two are the same but 34008-52A is a cast part, the other, 34008-52, I think is fabricated. I was told cast is the better one because it lasts longer the in curves. The fabricated one is also not as precise. Any thoughts ?

I never had a problem with either, Pa!

My handshift 65s' had the early drum, for some reason.

(Along with bushed 3rd gears...)

That implies the later drum was designed for foot shifts.

PS: The new AMCA forum format really sux, and few probably saw your post!

I don't care for the AMCA forums new format either. Thank you for the input Cotten. I may need to find one of those shifter drums.

Got my answer to my last question. Seems most cams are stamped with that number but the number is not in the parts books.
