As we know it nobody makes a good after market rod for the 426. I've spoke with both carrillo and falicon neither of them have one available carrillo will not have one for several months, however the boys at falicon said if we could rally up at least four of us 426 riders in need of high performance rods. They will run a set of them special order. These will be the knife rods I believe you can check them out at faliconcranks.com The rods will be priced high because it is a special order 210.00 a piece, but worth every penny. If anyone is interested please get ahold of me firstname.lastname@example.org or 269-317-0198 so I can set this up thanks.
