Thats an accurate statement patrickt. But the issue is: How well does it do from low rpm when you nail the throttle?

This discussion of cam profile and timing is relevant to the thread because timing issues are what led to the ring gear failure in the first place!

Not only, "Is their a hesitation at low rpm and going to WOT?" Also, I have found more advance makes a big difference on how well the car recovers from fuel slosh following hard braking or cornering. Now how many threads have we seen where people ask about that? Hesitation, motor dies at stop signs, bogging during cornering, etc. While carb adjustment and modifications help, TIMING should be at the top of the list to get a handle on it.

Having the WRONG ring gear didn't help, but still, hard cranking with the advanced base timing remains the central component.

Oh yeah, my cam is Comp Cams 292S, flat tappet, as recommended by George at Gessford. I don't think they make that profile for FE's today. IF I was going with a new cam I'd give serious consideration to dual pattern cam. Different profiles for the exhaust and the intake. Because of my high gear ratio's I needed a cam that would pull well from a lower rpm than I was running, which was a 3000 to 7000 profile. Real bad bog at low rpm I never could overcome, it just hated ANYTHING below 3000.
