in your guys opnions.....who makes a good bearing for crank/rods/cams?

also who makes good piston rings

I've been using Clevite recently...stay away from ACL...they've recently changed ownership and are outsourcing much of their product line with shitty QC. 

King bearings seems to be OK as well.  Their "alecular" bearings are supposedly more forgiving than the Clevites but I'm not sure if that's good or bad.

Rings....most are made by Hastings anyway, regardless of the brand.  They all have the same piece of paper in them explaining how to install them.

What kind of motor are you putting together?

Michigan brand is a good quality bearing.

Sealed Power is good for rings.

I agree too

Been there done that...still disagree with ya...Just my preference...... Yet I appreciate you preference

Total Seal rings for marine deal and marathon motors..A pull truck builder turned me on to them, they're in Phoenix AZ I think..

Otherwise Speed Pro from FM. To be honest, never spent a lot of time checking end gaps on those, I just push a ring from each piston in it's cylinder and look for daylight, I'm lazy that way..    

Always used Michigan/Clevite bearings and never really had any issues.
Anything over 5,500 RPM and I use "P" series bearings and under I have stuck with the standby "H" series.

I was taught by a circle track engine builder, so that is where that comes from....Use what works for you.
