    Use to be an part of Carrillo. JE, Wiseco, and Carrillo were all part of Dover Dover Corp. Then Carrillo was snatched up by Pankl, and along with CP pistons. K1 is still part of Dover. I know K1 stuff is sold thru Wiseco.

    Good stuff when I bought it last. They are big with the MOPAR boys. Decent cranks, and I really like their connecting rods.
    Like Chris said, I don't think its any strong than Scats stuff. I was running it before I was getting the "price" on Scats stuff and really started liking Scat -2 lightweight stuff. I think the K1 stuff may have a slightly nicer finish than Scats standard fair. But no comparison to Scats lightweight -2 stuff. I still buy rods from them because they sell a length I use alot, and Scat doesn't make.
    If you getting a decent price on Scats stuff, I don't think I would spend an extra dollar for the K1

    Customer brought me one to use in this blower build. Actually, I like it lot. Side by side, it's a nicer crank than the Scat. (Standard, not lightweight). Measured within .0005 througout, nice counteweight design, nice finish in the fillets, nitrided...not bad at all. My machinist is a dealer for K1, but I'd never heard of them. Someone else told me they use them in SB Fords and are taking some serious abuse.

    Here's a few pics:

    Like I said, they fall somewhere between a Scat standard and a lightweight. I take it, thats a 4.25 short rod crank. If its a 6.385 rod crank, then the Scat lightweight has it all over them. There is no counter weight on the rear, and the flange is even clover leafed.

    They are nice crank for the money. It just depends, what you pricing is for other cranks. If you have good pricing with certain companie then you have think twice to buy something else. Like how much more are you willing to spend for one of those, over a standard Scat, or how much more over the K1to buy a Scat lightweight.

    It is partiallycenter weighted if that is important to you. Kind of reminds me of a Eagle 4.25 forging

    In fact, its scary similar

    It may be the Eagle forging, or the RPM or some other...I dont know. This is a 4" stroke for a 454.
