for every day and mild use i would use a RV cam like denny said the hi stall will not be EZ on gas .i would not use leaky lifters like rumrumm said .why not just build some thing off the bat that will work good then try to stick a big cam in it. if your just blasting it down the road every now and then stick a big cam in it. but if your going to drive it use a RV cam?
