Help with Lifter Choice
I am building a street/strip SBC with a solid roller cam. I have a set of comp cams solid roller lifters w/o the bearing oiling provisions already but have been getting mixed advice on what I should run. The truck the motor is going in will see less then 1000 miles a year and most likely not more then 50 miles in a weekend. It will mostly be for index/bracket racing and hitting the local car shows maybe 2 times a month. My springs set up with 155# on the seat and about 430# open and the engine will likely never see anything over 6500rpm. I am not running oil restrictors and have been told if not running restrictors and with my lower spring pressure not to worry about it. I have also been told with out something like the HIPPO or Endure-X style lifters the low rpm of street driving will kill the needle bearings. I have never used a solid roller for street use before so I have no exprience myself to guide my decision. What do most of you run in street/strip engines? Will my current lifters suffice or should I get the HIPPO/ENFURE-X style?
Thanks, Jay |

I would tend to agree Jay,, that's some pretty soft springs in the grand scheme of things (I'm runing 320# seat and #830 on the nose with a 2.12 titanium valve) in my Nova small block. I run Crower HPPO lifters and change them every other season. Have never had a failure (knock on wood) There as good or better than any HPPO lifter out there IMPO. Isky Red-zone or Crowers HPPO are tough as nails.
I don't know who makes the Comp struff but with those light springs (which BTW appear to be a hydraulic roller spring???) I sure wouldn't sweat it. I WOULD, for peace of mind make sure the lifters your using is a Morel built lifter and call it a day. jusy my 2¢ |
Re: Help with Lifter Choice
The needle bearing deal is mostly because of "sloppy" valvetrain. Lifters bouncing around in the lifter bores and etc. I don't think the spring pressures are whats causing lifter failures.
I agree with Marv on the Morel type lifter. You can call Chris Straub and tell him I sent you if you want. He sells a TON of lifters each year and ask his advice. 1-423-391-7771 |
