MONGO510 Posted August 29, 2006 Share Posted August 29, 2006 Does a Solid Roller lifter have a shorter life span than a solid flat tappet in a street use situation? Quote Link to comment Share on other sites More sharing options...
MONGO510 Posted August 30, 2006 Author Share Posted August 30, 2006 Anyone? Quote Link to comment Share on other sites More sharing options...
dr_hunt Posted August 30, 2006 Share Posted August 30, 2006 Yup, but that depends on how often you change oil, spring pressure and how often you adjust the valves. I've put about 140K miles on a solid lifter street motor. Went about 70K each build. Quote Link to comment Share on other sites More sharing options...
MONGO510 Posted September 1, 2006 Author Share Posted September 1, 2006 I am using a Howards Mech. Roller cam and kit, Duration is 242@.050, lift is .567in with 1.5 rockers, LSA is 110. I will be using 1.6/1 roller rockers. Recommended seat pressure is 175# and 400# at .567 lift. I calculate that my lift, with 1.6 rockers will be .605in., so my spring pressure will be slightly higher. Question: are these excessive spring pressures to run on the street?
