If you're primarily running 1/8 mile, then I think it's going to be tough for that 306 cam to show much improvement over the old cam, in that combo.
The speed improvement is somewhat promising though.
The speed improvement is certainly hopeful. It may be more advantageous to look at a different cam rather than re-stalling the converter?
I'm sorry if what I posted upset you but to properly diagnose an issues you got to know the facts. Cam timing can and will make the difference between a dog or a race horse. Again I'm sorry and will butt out now.
It takes more than a comment on the internet to upset me.
