every rod i ever seen was stamped 0, and i have seen a lot of rods.....



all jokes aside, lol if all the rods ive seen say 0 then going with the numbers on the crank alone makes perfect sense!

i use to use oem bearings, but now at the cost and the fact that i havent had issues with acls (knock on wood) no pun intended i use those in almost all my builds now

thx but I think I'll stick with oem and get the machine shop to mic it out. Gunna set it around 0.0015 right in the middle. It's a burnt up p10 motor from pap. I've got a few 4cw se cranks laying around I'll probably use. I'll post up pics of my build if anyone cares.


You're a brave man if you are intending to build a FORGED motor with OEM bearings. Not a good idea.

Can you elaberate why? Also, my head is ready to go but i need some valve seals. The Nissan dealership quoted me about 8$ a seal??? My local parts store has the entire 16 from felpro for 33$. Any reason I should go with oem ones?thx

Was there any final word whats 100% right way to choose rod bearing? As there are two opinions in this thread from respectable members and It does confuse me. Thanks

EDIT: This is for Roller Rocker and it does confuse me even more

ROD BEARING: Take the 4 digit stamped on the crankshaft. That's it.




There are 4 digit for the rod bearings because there are 4 rods. The 5 digit is for the crankshaft main bearings because there are 5 crankshaft journals.

With all due respect to the Honorable Mr. Miko, we disagree on this point. The FSM is very clear about how grades are found. In no place, in any FSM i know of, does it tell you to factor in the # on the side of the actual rod.

and for the price of acls just get them in standard size

MAIN BEARINGS: use the chart to find the grade

1. take the 5 digits stamped numbers from block and crank
2. for the block #, go across the columns(x-axis)
3. for the crank #, go down the rows(y-axis)

For example:

Block #'s = 1 1 1 2 1
Crank #'s = 2 3 2 2 2

For the first bearing, take block #,which is 1, and go across(x-axis) and go down the chart the match up the crank #, which is 2, and you will get grade 3.

Final grade will be 3 4 3 4 3.


Numbers stamped on the block


Numbers stamped on crank
