Yet another Vic Jr vs Fast 90 thread
Yet another Vic Jr vs Fast 90 thread I currently have a ported Fast 90 / 90 on the setup below and wondering if there are gains to be had with switching to a Vic Jr setup. Right now I'm putting down around 495 RWHP and 465 ft lbs with HP peaking at about 6100 rpm, so it's not a high revving combo.
