1961 Triumph 6t pre-unit upgrade!?

[roosterking]

I'm familiar with the Triumph T120 unit construction; Now I just got hold of 1961 6T case. I already know I can upgrade the top end of my case with the 9 bolt cylinder barrel of the T120 (with 9 bolt head...). Here's my questions, can I do the same with the cams and crankshaft by using those of the T120 unit? Thank you for your help and any advice or suggestions would be appreciated.

Yes, they are interchangeable. I was just pickin FOURACESWES' brains about the cranks today cause my searches came up dry. I'm lookin at puttin unit guts into mine. some people favor the 66-68 cranks, as they are about 2.5 Lbs. lighter. as far as cams go, damn near anything goes, just depends on your riding style. just start searching. there's a wealth of info on cams on this site alone. Stan Shenton and Dwain Taylor. google 'em.
