I had a 4.15 stroke big block crankshaft that started out with Mopar size rod journals, reground to the big block Chevy 2.2 journals. Its time to buy connecting rods and I was wondering if there were any major downfalls to running a Chevy width connecting rod on a Mopar width journal? Will there be any issues with the extra side clearance? Thanks for any input!

I`ve been runnin em for almost 9 years and it SEEMS to be working ok so far w/about .035-.050 clearance per journal.

First one I put together bout 5-6 years ago, had .075-.080 side clearance..that engine was one of the best ones yet..easy on bearings, and what seemed like indestructible...
dont worry.

Indestructable and a helluva ride ESPECIALLY on the street.

It would only be an issue with very high rpm, fly-weight rotating mass and super low compression height; like CE or PS.

The oil clearance is a non-issue, but check to be sure the rods can strike the cheek before the pin boss touches the rod eye.

many years of carefree high speed motoring here.

Thanks for all the replys! Looks like I have nothing to worry about.

I believe Eagle sells a rod that has Chevy 2.200 rod journal and has Mopar big end width of 1.007. That is if you don't already have rods.
