both times i used RAS and RAU I was disappointed and over charged from the original quote on both time and money down NO MAS twocents
I've used a bunch of Harland Sharp aluminum roller rockers on many different motors for a long time now with no bad results, current bracket motor has 840 Lbs. over the nose with 325 lbs. on the seats with Manton series 5 7/16 pushrods, pulls hard up to 7300 RPM with no issues of power dropping off up
I'm going to try shifting it at 7500 RPM this year, raising the low gear shift RPM last year from 7000 RPM to 7300 made 2 MPG increase in the 1/4 mile with almost no ET gain, 8.862 at 148.?? MPH shifting at 7000 RPM. 45 minutes later in the other lane shifting at 7300 it ran 8.866 at 150.?? MPH confused shruggy
