572 RB Street motor advice?

I can go along w/ the 270 head .
That being said , a guy could probly find a hyd. cam kit that would work w/ them, I`d think >--------?? Probly aint gonna put out any more power than the 815 horse rat .
I had a hydraulic roller ground for use in a 48 degree R3 block so a BBM is an easy one. No, probably not gonna be 800hp in street form.
