Aluminum bearings are the ones that every racer basically hates. They spall
and can't handle any overheating or grit. Trimetal is way more forgiving.
When I pulled my engine down with good Vanderwall bearings all the bearings
were marked up but still working and still in clearance spec (except for the
thrust bearings). A few years ago I used some aluminum ones and even though
they lasted the season, when I pulled them they looked scary. Chuncks
missing, seize marks, and way out of clearance spec. No wonder my oil
pressure was dropping towards the end of the year.

Group,
After our bearing thread a couple weeks ago, I contacted the folks at
King and just received their catalog. Their bearings are a bit different in
construction than the trimetals we have grown to love.
They have two lines of bearings -street, and competition- that aparently use
similar materials: steel backing with silicone/aluminum face for the street
and steel back with "aluminum, tin,copper, and other metals" face for the
race bearings.
I find only a few American V8's in the hipo section of the catalog.
Plenty of TR bearings in the street section. Has anyone actually acquired
any experience with these bearings on the street and/or track.
