AmericanPie I am going to take a shot at this. First off you are going to get different HP and TORK readings using basicly the same cam numbers on 2 different types of lifters. Ramps are different design. The question is how high an RPM range are you going?? Under 6500 rpm I go with rollers, hydro. Over 6500 rpm spend the money and go with the larger Dodge solid rollers, larger wheel,bearing and oiling system. However downside, adjusting of valve train on a regular couple hundred miles check depending on HOW HARD you beat on the car. George runs solid in alot of his motors, he is building endurance motors with good hp and tork. I have not seen a Gussford motor break at any of the R&G in the 12 years I have been going. I like exhaust noises not engine ones. A .020" gap between to moving parts(cold) is going to wear and need adjustment. Comp sells a groove tool to help put
oil on the roller wheel. It's a bleed down. I am going with Beehive springs, lite valves, and roller in motor 2. A dry sump setup with filters going into the pump will save the engine if a roller breaks. I am surprised that no one has come out with a aux oiling system for the lifters and cam. Splash is not the answer. Alot of people are running windage tray, so there is no splash, I have a canton with the screen but have hydro lifters in this motor. How big a motor where you looking at is also going to deceide rpm range and cam. I love tork motors. It's easier to change trans, 5 or 6 speed, or even gears, than to change motors, cheaper also.
Just my 2 cents. Rick Lake
