That's a nice start, but it fails to take into account the effects of displacement on cam profile. What would be a radical cam on a 326 would be mild on a 455. What would be radical on a 455 probably wouldn't run on a near-stock 326.
The cam shown should be a very streetable cam in a 326.
If you accelerate moderately fast to full throttle, do you still have that stumble?
