383 horsepower

Any build check valve clearance. I just went with same cam for the 440 I am building. Make sure to check coil bind and most likely will need valve seats ground to handle the lift as stock heads generally are good for about .520". Sounds to me like close to a 1:1 motor. That cam is good for a handful hP over stoc HP 383, along with the intake and headers. The limiting factor is the head. The stock chryslers don't flow we'll much past 450 lift stock.
