K1 crank and big HP.
 

I've been searching and not a lot of helpful info out there. I'm looking at the K1 3.9 crank to throw in my LS1. Anyone have high HP experience with them? I'd like to see 1xxxwhp one day, but honestly will probably never go much past 800 through a F1. It looks like I have to buy another crank regardless as mine isn't in the best shape and the price isn't much more for the K1 over a stock replacement. Plus the 3.9 would give me a little more ci to play with.

K1 makes good stuff. I want to say they are a division of Oliver or callies I can't remember which.

K1 is a corporate cousin of Wiseco and JE Pistons, among others

there we go. sorry about that.

And carillo untill a couple of years back.

K1 doe's make a great crank and their billet rods are great as well.
A stock crank will do more than 800hp so a K1 should handle a lot more hp than an stock crank.

If you go to the Wiseco website you will see K1/Wseco rotating assemblies.
