572 RB Street motor advice?

TF270’s are kinda small on a 572.

Just depends on exactly what you’re trying to do.

TF270’s and a factory style x-ram are going to want to peak really early.
It all depends on how formidable it needs to be in the 1/8 mile. I think most assumed it was more street than race. My choice given the cubes and a cross ram, would be a hemi.
