Ok going with Cranes Powermax Cams These are the Low lift 1 is a 1600-2200 cruise rpm Basic rpm range is 1000-4000 rpm with a 192/204 @50 duration with a lift of 467/498 2)is a off road towing economy cam.2200-2600 cruise rpm Basic rpm is 1500-4500 rpm 204/216 duration@50 with a lift of 498/530 Both these cams will work with the stock convertor. I may agree a little with French
But before buying another head. Try bring the Idle rpms up to about 900 and see what that does for you. It has been awhile since I ran the crane Rv cam But I think My Idle was around 900 rpms But I also had a stock head Yet on the motor. So this is why I may have to agree with French. But if your not worried about the MPGs I think it would far cheaper to step the cam up.You should also think about installing a set of bolt in lumps To pick the air flow Back up. Because I think you have a flow issue with the bigger valves On that small cam(again agreeing with French) hope this helps }[oooooo]
God doesn't like ugly.
