who would of thought that the LSX/Gen III motors would be such a big hit as they are. they are going on 11yrs and still such a huge hit for any swap. you can find them from vettes to fbodys to trucks to GTOs to impalas to SSRs to etc. and its nice that so many parts are interchangable.
with the minor issues they have they are probably one of the best design motors. others are going modular but GM stayed pushrod and still make great numbers, kinda makes you wonder why you would want a Modular motor. also some of the gas mileage ppl are getting with them makes you wonder why even have some 4 bangers. with ppl ranging from 15mpg to 30mpg its a good range and still have the power when you need it
At Lugging Speeds, Rhoads Lifters make your cam Smaller
At idle and lower rpm where lugging power and more torque are needed, Rhoads Lifters “bleed down” to make your cam smaller…about 10 degrees smaller. This really boosts low-end torque, engine vacuum, fuel economy and idle quality.
At Higher Speeds, Rhoads Lifters Make Your Cam Larger
At higher engine speeds where more cam really boosts mid and upper rpm power, Rhoads Lifters work to restore full lift and duration of your cam for maximum top-end power. As your engine revs higher, Rhoads Lifters bleed less because there is simple less time to bleed at higher engine speeds. Near 3500 rpm, the bleed action has virtually disappeared, shifting your full cam and maximum horsepower potential back into action
