I am actually doing the same thing right now and it couldn't be better timing. Right as I paid my P5 off from a rent to own place it developed a rod knock SO let the build begin. I saw these K1 Rods and I was wondering if anyone had any experience with them or if you know anymore about the company. I mean the price is like half that of the Crowers and Pauters, BUT both of these names I know have been around for a hot minute. Any info on these K1 Rods would be great as I am set to start purchasing and building the motor.
