Was helping a buddy put in some cam bearings in a 86 chevy 350 block. The box has them in what looks like the order they need to go into the block. Is this correct? I know the end bearing has 2 holes. But the other bearings have diff. part number on them. does this matter. And are the bearings in the box a "match" set. We also got one bearing that was way too small for the hole so we need to take it back, but was told that you cant jus replace one bearing that they are matched set in the box. Jus trying to get some specific info. This is a first time engine builder/build up.

Thanks
 
STOP. Do not proceed without getting this book.
"How To Rebuild Your Small-Block Chevy"
by David Vizard
old # ISBN 0-912656-66-2
new # ISBN 1-55788-029-8
I always let the machine shop install those bearings.:wink1:
 
Ok, let me start by saying the bearings ARE NOT a matched set. Unfortunately, if you screw one up you cannot buy just a single bearing. Now, the bearings are of different sizes on the OD. On one of the flaps of the box it gives you the part number of the bearing and it's location. If it isn't on a flap of the box then there should have been a piece of paper in the box with this info.

The front bearing has the two holes in it and IIRC the #2-5 bearings are the same and then the #3-4 bearings are the same.
 
I dunno about that though,
I had my last motor go, spun #8 rod bearing
It was Newer vortec 350
New rods, pistons, crank, bored out, all new bearings assembled as a shortblock for a hair over $1000 (when the canadian dollar was low probably 800 us)
All I had to do was clean and install the heads & intake, which the gaskets were included with the motor.
I think if you already have something to start with crate motors aren't worth it, now if you didn't have a block thats a different story.
 
Thanks 4x4high. that was the info I was looking for.

As far as the rest. well. not so sure how it pertained to my question, but atleast it helps your post count. LOL. :D

Your local Chevy dealer, prolly worth it to call around for pricing. I found a coupla hundred dollar in variance between three dealers in a fifteen miles radius.

Summit also sells 'em:

Stock replacement type, or hi-po:

Obviously the hi-po ones cost more, but you get the idea.
