I have a Ohio 4.15 forged crank in my 499 Challenger. I have fun it for 2 full seasons running two classes a night and have around 600 passes on it. Will be pulling the motor this winter to check it all out. I am very happy with it and it needed zero extra work. Best e.t. is 6.01@112.25 in the 1/8th at 3300lbs.
