Cast v Forged Crank
I have heard a of a lot of issues with Eagle cranks and rods. I bought an Eagle stroker crank and the rods were out of spec. My machinist corrected the problem, but I will never buy another Eagle product. My machinist swears by Scat parts. Both are made in China, but Scat has better QA/QC. Both make cranks are supposed to handle up to 600 HP, but I would trust the Scat to 600. The Eagle would be pushing it at 500 HP IMHO.
