If i"m reading that correctly - you want to install a used 360 cam from a Winnebago in your 318? You'd be better of with a new small block mild truck type cam, or build a mild 360 with the RV 360 as the "core". I like 318's in trucks myself, personally. As Alaskan TA alluded to - what is your axle gearing?
4:10 or 4:11 I cant remember. It runs great I just want enough torque and power to haul both heavy loads and a little ***. I guess what I'm looking for is the perfect vehicle where I turn the key then giddy up.
