I just put in a used 454 in my eliminator mojave. Motor sounds real good but when the boat planes out it seems to hang out at 35mph and is at ful throttle. Pump worn out maybe? Seems like there is no power but is running real smooth and sounds good. Berkley jg with 454, oval port heads, edelbrock 2-0 intake and edelbrock 750 cfm and hei.
