Big block Chevy rods with widest bottom-end width? - 02/27/13 03:28 PM
So it appears that Eagle has discontinued their 6.700" connecting rod with the Chrysler width (1.007" BE)
Of the various companies that make a 6.700" big block Chevy rod (2.200 big end, .990 pin) - which ones have the widest bottom ends?
Though one is led to believe that large side clearances at the rods are not a big deal, psychologically I'd prefer to keep them a bit tighter and not add .020" if I have to.
Thanks in advance

Any effect on oil pressure at idle, having the narrower rod ends?

Eagle had a 6.700 rod with 2.200/.990 CRS6700C3D but it was discontinued 2 years ago.
That doesn't stop some places from showing stock, or continuing to list them on eBay

afaik you're not going to find 6.7 long, 2.2 throw chrysler width rods from anyone. i "think" eagle has a 6.76 long rod with the other dimensions you mentioned. if you're asking about who has the widest chevy width rod i wouldn't bother as now you're into manufacturing tolerances.
i'd say if you need a 6.7, 2.2, .990 pin rod you have two choices either custom rods to get a wider BE or chevy rods with the standard .990 BE width. there are plenty of engines out there with a lot of side clearance and no one likes it but i can't remember anyone having real issues doing it. as for oil control imho the bearing clearances are what primarily dictate that, of course pressure and viscosity come into play as well.

I asked a similar question a few months ago. I'm not aware of anyone selling a 6.700 long rod with the 2.2 journals and the Mopar width.
It would be great if Performance Only had some available. Eagle still makes the 6.76 length rod with the 2.2 journal and 1.007 width but they were on back order a couple of months ago. Molnar is also making a 6.76, 6.86 and 7.1 rod with the 2.2 journal and 1.007 width.

Cool - thanks for the advice. Part of the search is because I have a beautiful 3.9 stroke American-made MP crank, fully indexed and the 6.700" rods will be perfect for a zero-deck motor with my pistons (and block correction)

I just received a set of the Molnar 6.7 rods yesterday for use with a 3.9 stroke crank. I already had pistons when I found out that Eagle had stopped making the 6.7 rod with the Mopar big end. Lots of places still list them on line as they haven't updated their web sites in a long time.
