I do find mine loves a ton of initial ignition advance, the more the better. But I attributed that to having this cam with a low CR, not to the cam design itself. I think my combo with a 3000rpm converter and 4.10's would really make it haul in the bottom end and that's in the plans.
I do not run this cam, however initial timing is critical.
I had issues with my car not leaving properly and slow 60' times (high 1.4's - low 1.5's) for waaay toooo long!
After beating my head against the wall
I limited the advance in the distributor and put 20* initial timing in it and 37* total (you may require diffrent).
Wow what a difference
Now my best 60' is 1.389 with consistant 1.40's.
If it falls off after 4,000 rpm then you might have a fuel delivery problem.
My car would hardly lift the tires 3" before, now look!
