having a little issue...

no! this was with the JP double roller timing set! to get a base line i started at 0* on the crank sprocket and it was at 97 CL so i backed it off to 4* retard and i got 102... weird but it works!

It's the cam/crank key position/timing gear combo

all are different.

I also run a JP billet set on my 340, it's retarded 6* to get 5* advance, then I also have a 1/2* cam key so...5 1/2* advanced, it was the only key I had left at the time.
