Default Re: Finally some Cam Degree Numbers - Now what?

Don't confuse this with the "LSA", two totally different animals!

I would not pay too much attention to the "events", it's difficult at best to dial in any cam with the "4" event numbers!

Thanks, Gary

P.S. Been using the "ICL" method for more than 55 years now in all our builds!
With the 77B, the exhaust c/l will be the same as the intake c/l. Isky says 111* for both. Also Isky specs their cam events at .020 lift. By using Russ/40 numbers, I come up with 120* c/l which would indicate the cam timing is off by one tooth,
