Good read, thanks for posting that. I spoke to my dad for another perspective and he said he thought the victor would be too much head for my big heavy street cruiser (late B 4 door) and that the RPM would still work well with the closed design. He may be intrinsically biased though towards that style head since he still has his 67 440

Not many options to pick from, guess I will stick with the RPMs in my build plan and factor in good quench. thanks
