Greetings . . .

Another thing you may want to check with your grinder on is what was meant by "that won't work." Did he mean that the engine won't run right or that he couldn't grind a core that way?

I had the guys at Delta Cams regrind a cam for me. The Isky DP #2 specs were what I asked them to shoot for. But there are limits to what can be done given the core they are working from. In my case it was an NOS TRW cam for the early 235 Powerglide cars.

They were unable to duplicate the exact 'advertised' DP #2 durations, but they were able to provide more lift:
----------Timing-----Lift----Adv Duration
Intake----20.1-47.6--0.40878---247.7
Exhaust--64.4-20.1--0.39862---264.5
And this added lift leads me to believe that the .050 specs of this regrind are perhaps better:
----------Timing-----Lift---.050 Duration
Intake----1.7-23.1---0.40878---204.8
Exhaust--51.2-1.7---0.39862---232.9
then what Isky offered on the DP #2.

But since I haven't had a chance too run it yet - it's all 'on the drawing board' at this point ;\)
