the block has to be machined to fit the bearings unless you buy a bow tie block set up for the bearings and you need a special cam,not cheap to do. :chevy

This was used along time ago inthe 60s and they discoverd that it doen't help make horsepower or reduce drag
If you think about it the oil film under pressure keeps metal to metal contact from occuring.
Bottom line is save your money and stay stock in reguarding the bearing set up

roller cam bearings are still used in applications where ultra stiff valve springs can overwhelm plain bearings, but you'll never see these springs on the street

Re: roller cam bearings? (clem zahrobsky)
Back in the old days, 60s, there were 1/4 speed cams. The cam gear would turn the cam at 1/4 crank speed instead of 1/2 crank speed. The cam profile was on both sides of the cam. That is, each lobe was a double hump, 180 deg from the other. Seems like a good idea. Haven't seen one in a long time. I wonder why.

Re: roller cam bearings? (antenna)
thanks for the info..
it doesnt cost as much as you may think. a standard journal small block cam is still used. just have to cut the block to big block journal size.
i think i agree with you in that it wouldnt be cost effective. the only upside i can see to doing it is durability. and well, if your cam bearings are worn out , it would be best to freshen up the whole engine. so , i guess im gonna skip out on it.
p.s. antenna.... you completely lost me.

The vast majority of cam bearings are replaced because they get eaten up in the hot tank when the block is boiled out for a rebuild. They rarely wear out or fail. Good luck, and...
