Well .500 lift as mentioned is a good rule of thumb with stock springs. You can run a larger cam but valve float may become an issue, besides the springs will wear out quicker if not bind in some cases. I don't know the modifications or intended usage of the engine fordzman gave to comp cam but I called them and told them 2wd stock truck 351w aftermarket intake and carb and told them I would not be towing just wanted the truck to perform better all around and they recommended extreme energy 256H which keeps the lift well below the .500 with the greatest lift being .484 on the exhaust side and even lower on the intake. Whatever they recommend should do the trick so give them a call. Good luck
