What should the cam bering oil holes be clocked at. My dumb *** forgot to check the old bearings befor I knocked them out. What sucks is that all the local shops want me to bring the block in and charge me to install the bearings rather than tell me how to install them "b@$^@*ds!"

 

You'd better have the right tools or you'll end up ruining your bearings. You don't say what kind of engine???

If it has a grooved bore, you put the hole at 2 o'clock (looking at the front of the block, crankshaft at 6 o'clock). If it's just got a hole, then you line up the hole in the bearing to the block.

Good luck.

If you don't have the right tool, it's better to have the shop do it. You can get a cam bearing installation tool pretty cheaply, but unless you rebuild more than the occasional motor it may not be worth it. But, of course, you must line up the oil holes in block and bearing shell when installing them. Be sure to put each bearing in it's proper location as the OD varies for each position in the block. They should be numbered.

Actually the grooved bore engines, the hole can actually be placed anywhere but for the best oiling wedge you will want to place the hole between 9-10 o clock with the block up side down, which translates into 3-4 o clock when looking at the engine upright. This provides the greatest amount of oil film strength where the load is the most downward on the camshaft

 

I was always told 2 o'clock for the same reason. So I wouldn't just place them anywhere.. but I'm ****.
That's your "10 o' clock upside down" BTW.

I really apereciate the info, I know it's not all that critical for a motor that will never see the top of 3500 but I'm going to be spinning this mill to the 6000-6500 range or higher on a regular basis. By the way it's a vortec 350 out of a 98 3500 truck. It's going in my 92 RS with LT1 flat tops, a Lunati roller (230/230 @.050 - .480/.480 lift), stock vortec castings milled .025" w/Z28 springs and high mount retainers, .015" head gaskets, and a Prof. Prod. Hurricane intake toped with a NOS super power shot plate and a 750DP w/Proform main body. I'm hoping for at least 430 on the motor and up to 580 on the spray. I had a 305 in the car making 300 all motor and 400 on the bottle but that got slow in a hurry. Well thanks again and I'll be posting some times as soon as I get the car going.

 

I do have a cam bearing tool. I bought it off a bum looking mexican dude for $30.00 right after I got the 350. Talk about timing.
