572 RB Street motor advice?

700-800HP is range I am shooting for. Car will be caged and tied together with overdrive and mufflers for short street trips to shows (20-30mile). Want a high 9 - low 10 second car that isn't a high maintenance 14:1, radical roller cammed trailer queen. I'm open to adding 105 octane to the tank, but not filling up with Q16. I know I could put Predator heads and big mechanical roller cam in it and turn higher RPM, but that isn't what I want.

The Duster that I'm doing for Car Craft will have enough power to run high 9's and it is very street friendly. It is a pump gas 512 with EFI and a hyd roller cam. It is 600+ hp with 3100 lbs so a weight to power ratio of a little over 5. That works out to high 9's if everything else is working properly. Sometimes it takes a lot of work to get the chassis to run the number but in theory it should do it.

So if your car is in that weight range you don't need a 572. You should be able to run high 9's or low 10's with a pump gas 512 and a Sniper Xflow. I think you might need a solid roller to make 700 hp but who knows, perhaps someone can come up with a hyd roller lobe that will get you there.
