Degree numbers for small Webs & 1397

(1/1)

:
Hello all. What would be some good cam numbers to run on a 13:1 1397 with the small Webs and ported head? Working on a little project. Thanks.

TDC:
105-108

:
Wow. So I guess I better change from the present setup of 106.5/102.5.

Any advantage to running the exhaust cam that high?

ZXALAN:
It just pushes the power curve upward.  105/107 works pretty well to. I rode a busa with a 1397, yosh cams with 106/109 and the main grunt of the power was 10k up.  Depends on what you want. I would say 104/106 is the best compromise between midrange and top end power.

ALAN THAT BIKE YOU REFFER TO HAS SOMETHING WRONG WITH IT IT MADE ONLY 170 SOME ODD HP
SO IT WAS ABOUT 30 SHY
