You mean they make a narrower rod bearing to account for this? Who would have thunk it.

See the edit above:
I hope you are not telling me you can, or expect to 'ride' on the radius of the crank journal.

You testing me? This is crank tech 101.

No I get ya there but side clearance is usually measured between the rods... so a narrower rod journal will in turn close that clearance.

Wanna know what I think? I think you and MG are in cahoots on this.

Re: Connecting Rod Side Clearance

I could be wrong too..... Either way I wouldn't stress about it and it's not easy to fix.

Hell I found some SB2 bare castings on ebay but once I noticed that they were not SB2.2's I knew why they were so cheap..... if they were 2.2's I would have been in cahoots with MG.
