Best cam bearings

Post  garys gt on February 22nd 2014, 4:09 pm

What kind of cam bearings would be the best for a 557 with scj aluminum heads and a solid lift flat tappet cam. I have not bought the cam yet. I have read about the wide cam bearings and coated bearings. At what point are the wide bearings needed and when are the coated bearings needed.

The wide bearings are a nice feature to have especially on a big roller w/heavy seat pressure,but w/flat tappet not that big of deal imo.

I have ran both and both worked great the plain non coated looked just as good as the coated bearing did when I replaced them I replace mine when I freshen the engine up from what I have understood the coated bearing is supposed help on cold start up and last longer.

about what do the wide bearings cost. I have seen the regular width bearing for sale and seen prices. I have not seen the wide bearing for sale. I read they were 5 number 1 bearings 351 Cleveland size.

If your block is designed for them, roller cam bearings are better IMHO than conventional.

my block is a factory block so roller bearings will not be a option. will pm both lem and randy and see if they will get back to me with info. going to need a cam at some point. thinking about going with a custom cut solid flat tappet. any ideas on what lift and durations might work well with my build. I was thinking 260s @ .050 and 650 lift range.

IF you are NOT using a hardened steel camshaft then, you CAN'T use them without destroying parts.

I wouldn't want one over the other and sure wouldn't machine a block to use rollers. I have both without problems from either. .....

So in a mild 460 would stock replacement bearings f30 be good enough for about $20?
Or durabond fp30 bearings for $30
The durabond fp30T are the coated bearings for $60
