I am installing cam bearings in a 350 small block. It is my first time. i have the tool to do it with but just a couple of questions. The bearings have position 1 2 3 4 5 . I am asuming the front of the engine is #1 position and the rear of the engine is #5. should i install #1 bearing first then #5 #4 #3 #2 or does it really matter. I know i am suppose to align the oil holes in the bearings with the oil holes in the block. Thanks for the help...

the oil holes should be at the 4:00 o'clock position with the block right side up.

That is one of the things I have the machine shop do for me when I have the block machined.

Not a good idea in my opinion.

You cannot clean out the passages with a brush with them in. The block straight from the machine shop is no where near what I call clean. Just my 5¢.

Havent had a problem with one yet. The machine shop that does my work is very meticulous and the guy that does all the work spends about twice as long as the other shops I have used. I dont think he would slam a set of new bearings in a nasty block full of shavings.

I finished installing them yesterday. It is really not that hard of you take your time. I took my time and used the brushes to clean out all the passages. I have a full set of brushes for cleaning blocks. Used some brake cleaner as well as my high pressure washer. First i sprayed the outside of the block with Easy Off oven cleaner to melt all the old grease. After installing the bearings i used a soft insulated peice of copper wire to check the alignment of oil holes in block and bearings. The instructions on the new cam recomend leaving valve covers off whole breaking in the cam to observe if all sixteen pushrods are spinning. I never thot of doing this. I usually have the valve covers on at time of break in. Since I have had 2 cams fail in this block it sure sounds like a good idea to me.I usually pay the machine shop to do it also but now that i am retired a dollar that i don't spend is like a dollar i am paying myself..
thanks for all the help...

make sure the cam fits into the bearings before putting the rotating assy in the block. it is no fun to change cam bearing with the rotating assy in the block. been there and had to do that,not fun

I did that first thing after installing the bearings. I wanted to make sure cam rotated properly before replacing the rear plug behind the rear cam bearing... I will also install the cam before installing the crank when the crank comes back from machine shop. It is a lot easier to insttall the cam with the crank out of the engine..
thanks for the mention tho old as i am gettin i could forget it the next time....
