Looking for some input on these cams.I have not seen anyone with them but how do you think they will respond on a 107" 11:1 comp. set up?

xzo124:
Haven't ran the SM600 , but he recommends 10.5 / 10.7 . I'd say either the 662-1 or 2 would be your best bet . What bike you putting it in ? I run the 662-2 in a 124 , AWESOME !!!...xzo

Ive had the 662-1s in a 107 set at 10.8 and it ran like a sob. With even more comp. they would be even better. No experience with the SM660 tho. I am currently building a 117 with the 662-3s.

Don Dorfman:
Got a set going into a 103 @ 10.7:1 and my heads, geometry fixed, 55 TB, Fatcat. We will see

aharp:
Don, I am sure that will be a runner. Keep me posted. I finished a 107 with the 600 last week. A poor choice of exhaust (Cobra staggered double barrel) and it went 119ft/lbs easy. Incredibly quiet cam. At 11:1 I'd probably go with the 662-2 though. Just me.
