ok first let me fill you in its a 1986 truck 460 bone stock. has a manual. this truck is a f-250. this truck will be a daily.. but i want to use it as a calling card so to speak. the truck will be used as a mobile mechanic truck. I,m looking at a Comp Thumper cam. I'm not wanting race power. more just for the radical idle. the truck has air and power brakes. would this be too much cam? the truck will mainly operate in the 2000-3000 rpm range due to a butt load of highway. if this cam is too radical any suggestions on what i want ? my main goal is a loapy idle. the low gears of the rear and granny low will compensate for the duration of the cam. Plans are also a rpm dual plane air gap headers and roller rockers. rotating assembly will be stock. and stock heads.
