Rod cap install question.
Ok this is a stupid question and I am pretty sure I know the answer already but I need to double check and I cannot find this addressed in any of my manuals.
On the rod end and the cap end there is a notch that the bearing locks into. When you mate the rod and cap together these notches should be on the same side but one closer to the right and the other closer to the left correct?
Thanks

together thats all you can do. Upper/lower bearings are the same
with the tabs off center. You pull a bearing out of the cap flip it
over the tab on the bearing then matches the rod.

You got it. Make sure when it's all together that the notches are facing the outside of the motor..not towards the cam.

Both sides of my rods are beveled thats what was confusing me a little. I don't remember this last time I put it together. At some point in time someone had marked the rods 1,3,5 etc so I put them in like that last time and it ran fine. I am putting them back in the same hol;e as before so I guess I am fine. Ikept looking for a difference in the sides of the rods but like I said they were both beveled exactly the same. I have the drivers bank installed now. Thanks
Ok Jim it is time for you to 
again.
Not really sure what you mean by facing the cam. Here is how mine are if you are standing at the rear of the block and looking forward to the front. Looking at the drivers side bank the bearing notches that the tang of the bearing fits in are on the left side of the rod. Again this is how they were before when it was running and someone had marked the rods at one time for there appropriate hole but that does not necessarily mean it is right. Is this right or wrong??
Thanks

You have it correct. I'm assuming we have block turned with head side up right? Just as it sits in the car.
With the notches on the *left side* as you described.....when the piston/rod assy are dropped in and attached to the crank...the notches will be on the *outside* of the lower assy and facing outwards to the pan.
Another way to envision it is that many years ago, many engines used a little hole drilled through the parting line of the rod caps right through the bolt hole. This hole was opposite the tangs and was designed to squirt oil on the cam. So when it was all together, the tangs would be facing the oil pan...and the other side of the rod had an oil squirter hole that sprayed the cam as it went by.
In fact, there are some endurance engines designed similarly today where there is a hole drilled through the rod to squirt oil on piston bottom as well as cam.
You're doing well...keep after it!

Hi Wade
I was pretty sure I recognized that block from before you painted it...... I was standing there when you brought your block in to be tested.
Glad to hear that everything is proceeding smoothly
