Rotating assembly

[mocar]

Anyone have experience with eagle or K1 rotating assembly's? Which is better? Pros and cons opinions, need to be able to tolerate about 550 to 600 hp. Much thanks

I ran a K-1 crank with Comp Star rods in my 408 with no issues. The crank measured good everywhere and I wouldn't hesitate to use another one. I'd use Scat before I used Eagle. If you are looking at 4.00" cranks I recommend using either 2.100" or 2.000" rod journals and a 6.125" rod with .927" pins, shelf pistons are available.

Just avoid eagle cast cranks at the hp level. My scat cast crank has been very good. If I was buying a rotating assembly I would probably go molnar or k1
