Hey all, so I measured the big end rod bores yesterday torqued to RPM's spec with new bearings installed and I found them to be slightly out of round with the bearings installed.

Has anyone ran across this?
Measuring 90* from the bearing split all
#1 2.3018
#2 2.3018
#3 2.3024
#4 2.3015
#5 2.3019
#6 2.302
#7 2.3018
#8 2.302
Measuring 20* from the split
#1 2.3023
#2 2.3026
#3 2.303
#4 2.3028
#5 2.3029
#6 2.3032
#7 2.3029
#8 2.3033

Bearing part number CB-831-10
RPM light weight I beam rods in stock length being used.

Parting line is always wider, this keep the bearing from spinning. This is built into bearings. If you want to see if the housing bore is round, take the bearings out

Thank you!! I checked without bearings as well and they are round.

Next question is what measurement should I be using to check oil clearance?

Vertical oil clearance is the only number you can adjust, which is 12 and 6 oclock.

Ok guys, here's what I came up with on the mains. Opinions?
I was looking for around .003 should I be concerned with the .0037?

Its a little wide. But considering the kind of rpm that you are wanting to turn, I'd probably run them. Probably run a HV pump and experiment with oil weights.

I have a HV pump for it so that will help.

I'm wondering if its worth using my other block, although it would need bored and line honed.

I got this block from a guy I work with he had it bored .030 over and line honed with the ARP main studs. Whoever did the line hone must have got a little carried away I guess.

Would it be safe to assume that bearing life would be shortened with that big of an oil clearance?

The mains on the crank are the reason why you have a ton of clearance. The low side for a 3.00 inch main is 2.9994

.001 under the low side.

Run an HV pump and some oil weight

The original bearings were a MB2754P number .010 clevite
Recommendations on oil weight?

Yes sorry .0099, even I get wacked in the head looking at decimals for the last 20 years. 20w50 and I rarely recommend that but at damn near .004, its warranted in the dead of summer heat

Ok just making sure I didn't miss something!

Im contemplating just using my other block instead of this one... im going to check the cylinders first to see how they did on those.

What about a undersized bearing? I believe that they are available for standard and. 010 journals.

I have a .010 bearing in it currently.

Im going to pull the bearings out and check the mains without a bearing in it. Does anyone happen to know the main size off hand?
