Lunati has a cam that has same duration as the 340 cam and I think that the lift is in the low .500 lift range. A 4 barrel, headers, cam change, if you with something like the 340 cam you won't have to worry about compression or piston to valve clearance issues. All 360's came with a 8.4:1 compression ratio. Good flowing exhaust system is a good idea and a good tune.
