Onan camshaft casting number question

Does anyone know what the right camshaft casting numbers are for the B43E, B43G, and B48G? I know the P engines used a 170-4100 in the P218, and a 170-4101 in the P220, but I need the numbers for the B engines. Thanks

I worked on a B43E and B43G not long ago and it seems like the G cam had more lift and required a cam bearing with a notch in it to allow for clearance to install the cam. Not so with the E, I used a bearing without a notch and the cam went in fine. So... E has less lift and i would also imagine less duration which makes the E 16 hp. Other guys know more than me but it seems it was a cam and carb jet change to get the G to 18 hp.
Good luck with the rebuild! Jon
