Cutouts for Strip only, beneficial?

A 512 in a Scamp? That ought to EASILY run what you're after! I suspect you are traction limited? I'll bet that big motor makes a ton of torque and the car needs some help with traction. The cam is small for that big of a motor so the top end power is likely lower than it's capable of. But my goodness, with that much displacement, I see no reason you can't run what you want without cutouts.
Yea, the cam was designed with nitrous in mind. We are working on the suspension to get it dialed in better. No prep tracks are harder and that is all we run on. Also working on the EFI tune. Richard Nedbal did the original tune and some advice from Andy Finkbeiner has helped as well. A work in progress. I guess I will skip the cutouts for now and work on the other aspects
