470 vs. 500?

I'm not into big blocks, so just another opinion.
It depend on whether you want a High rev High HP or a High HP grunter.

I built a 408 stroker because it makes a lot more power, at stock rpm. aka no High Dollar Valve Train to make it live. I do love the sound of a high revving motor tho!!!
Good point and a reason I'm saving for a 408 myself.
