Thread: Connecting rods

Thanks for lead in Erik.......yes, you will get a ton attitudes and ideas for the length of rod discussion. Not only side load is reduced a stress worries about harmonics and load factors, you increase piston dwell at the top and bottom of the stroke. This increases combustion qualities on the burn cycle and scavanging factors at the exhaust cycle. Lingenfelter is no dummy and his knowledge comes from experience and years of doing this sort of thing. My opinion; go as long as of of a rod as you can stand to afford. One point of curiosity, bob weight seems a bit high for my taste. What pistons are you running and rods, etc? I like 1650 to 1725 on my SB rotating assemblies.

On dirt mod. engines that are in the 7,900 to 8,200 rpm area I like to run a 6 inch Eagle with the ARP 2000 bolts.
I use SRP piston #140348.
This combo. seems to live along time for us.
