How many hours are you guys getting out of a set of solid roller lifters? How big are your cams and what springs are you using? I am running a 264/270 duration solid roller with .740 lift and .020" lash. So far I have only 15 hrs on the motor and I am running Isky Red Zone Liftes with Isky 9945 tool room springs. Max RPM is 6500. I plan on running 50 hrs or 2 seasons and change at least the lifters and check the springs. For me 15 - 20 hrs a season is average, but we only have 5 - 6 months to actually boat. How many hrs are you guys getting and have you ever had failures?
Thanks,
Craig
