my stock roller lifter have well over 150,000 miles and I swaped them to another roller block with a lunati roller cam .485/.485 lift and comp 901 springs 2 yrs ago


all stock valve train and not a problem yet

turns right up to 6000 rpms with no valve float

ticking time bomb?...maybe..but I bet the rest will let go first on this 88 high milage jy cop motor
