I take it you just want the sound and arent concerned about how the engine runs, because either of these cams will give the noise but without the supporting higher compression the engine is going to be a stone. Need at least 9:1, if you are stock in the low 8s dont be suprised if the car is slower then it was. Also the 280 wont work well with a stock converter..the crane guy probably suggested a milder cam, which is right on the money with stock parts.
