I have had Crane hyd rollers in one engine for 20 years (no exageration) with not one issue. The hyd rollers last longer. The hyd rollers in my 10.5:1 CR 540cid engine produce 700 HP and 700 TQ - hyd rollers really work. |
I ran a solid roller 428 11to1 for 10+ years out on the street for an every day driver! No issues at all. I didnt restrict the
oil to the lifters. I used all Crower (they where the old school lifters) and it never let me down. I feel that part of the problem can be in the set-up. Or I'm just lucky LOL.
