Ls1 roller cam bearing I was searching online on cam bearings and I found this:
http://www.dpecorvettes.com/gpage.html
He did a roller cam bearing on LS7!!!
I know he used aftermarket block but I was wondering if I can do it on stock LS1 block?
anyone have any ideas??
Thank you,

Exactly!
The only time they save power is during startup when the oil isn't flowing.
Unless your running 8000 to 9000 RPM for several hours and want to run less oil through the cam thus saving a little oil flow. The babbit bearings are still the hot set up.

Sorry to bring up a very old post, but when i was researching roller cam bearings i came across this post.
Why is it they would not produce more hp? i would think with the spring pressure pushing the cam against the bottom side of the bearing this would ease the rotation of the cam. i know you said this is a misconception, but why does it lose hp?
Also in a motor built for ET but run on the street 8000 miles a year would this prolong bearing life with higher spring pressures?
thanks!

oh so the regular bearings should really have no metal on metal contact, but the rollers really do ride on the cam therefore creating more friction and sucking hp out?

If you need less oil at the cam, you can technically lower your pump volume (and pressure??), saving you hp at the oil pump. Theoretically, wouldn't this also lower oil temps? Can't see it being much...
