Clois,

I would check with Crower and see if they have the rollers you want. 2002 and 2003 I used CompCams mechanical roller lifers, and broke and/or wore out the lifters. First year broke the bottom off one, and had a couple others without bearings in the rollers. Second year, broke bottom off of 2 lifters and had another 4 without bearings. Called CC and told them that I had around 2,000 on their lifters, and they told me I was doin good, as the lifters should only last 800 miles and the springs 1000.

Spent last winter talking to different manufacturers, trying to find the problem. Basically was told by all that mechanical lifters won't live on the street under 3,000 rpm. Talked to Crower, and they have the HPPO option that pressure oils the roller, and their lifters would live, and also stand up to the spring pressures that I was running. Well after being in there for a year, and 3-4000 miles, they show no wear at all.

Also the literature that comes with the lifters says there is no need to have these rebuilt every year....like the "competition" These lifters aren't cheap at around 700.00 for a set, but it sure beats the cost of rebuilding an engine 2 yrs in a row.
