Timing a "unknown camed" engine....

thanks abodyjoe !!
I will read the article...and try to solve the problem... will keep you all informed...
the only question ...still in the room : THE CURVE.... I have a tuning set from Mopar...with a lot of Springs.. als those shims that go into the slots in the distributor...to change /set the total advance...
With the STOCK brown and silver springs the car is a little "lazy..and with the purple orange combo ...it pings a litte under load....

Greetings Juergen
