I have a friend with one he just wanted to have more power in his 5.9 magnum pickup and he installed a eagle stoker kit and had it checked and rebalanced locally and the front of the crank just snapped off on where the over lap is between the front crank pin and front main journal, there was a big bubble in there not to mention how much materiel is not there that is there on my SCAT crank and it was a disastor doomed from the begining and no magnaflux or anything would have detected it. His motor was very mild just had KB 356 pistons eagle rods no porting of anything and he even used a stock 5.2 magnum cam to get a little more tq with virtually no $$$ and it couldn't take that for a couple weeks and Eagle was of no help. Also if you look at there rods compared to a SCAT the differance is night and day and the metal is a much better quality so for the very minimal $$$ differance I would not use anything from eagle ever again, go with the SCAT and sleep well I am not causing global warming, I am just trying to hold off a impending Ice Age!

It dynoed 553 horsepower and I don't remember the torque off hand. Only pulled it out to put in a 416. The engine builder said that with a cast crank not to use a transbrake with it.

CJK440 master C Joined: Jan 2003 Posts: 9,982 Ansonia, CT	I bought a cast one for a 408ci interim motor for my F.A.S.T. Duster. It took me to 11.90 @ 114 which was very good considering how we had to run. I wrung it only to 6200 or so. The amount of meat in the arm between the 7/8 journal and the rear main bearing journal was scary to look at but didn't cause an issue. One very nice positive is that it didn't need any mallory to internally balance. I ran Eagle H beams and SRP forgings. 2017 Contusion Blue Challenger T/A 392 M6 "BLKNBLU"
