Where's the Wow?

I totally agree with RRR ,but i think if you have to advance a cam more than 6 deg. you better think about a smaller cam.I dont think the cam is why it has no upper rpm power.Usually a cam that is too big has nothing but upper rpms that is why I asked about the valve springs.
You keep sayin you degreed the cam. WHERE is the ICL? If you cannot answer that, you didn not degree anything.

That's a whopper of a cam for a stone stock pistoned engine with probably 8:1 or less static compression. Yup, that's right. The deck heights were terribly high on these engines and combustion chambers were generally big. I have seen then routinely blueprint at under 8:1.

So, you CAN make chicken salad out of chicken ****........if you will just listen. Advance that cam down around 100 ICL and that pup will come alive.

When you get that done and you KNOW it's right and not half assed guessed at (no offense) then recurve the distributor timing. You will want "somewhere" around 20* initial timing and limit the total to "around" 36* and you want it all in by about 2500 "or so" RPM.

Doing those two things alone can add possibly as much as 75 HP and 100 pound feet of torque....and no I ain't kiddin. None of this is in the carburetor jetting. It's all in the timing. Almost every stinkin bit of it.
