I have a bone stock, very fresh 401. I have never been horribly impressed with the performance of this engine. I am currently running a DUI distributer, Howell Fuel injection, and a Edlebrock performer manifold. Would it be worth my time to put a different cam in while keeping the stock rocker arms. Its in a 91 Wrangler that I use offroad primarily but I do enjoy driving around town when its nice. I am also running a 727 with a stock geared Dana 300 and 4:56 gears in the axles on 37 inch tires.

If it would be worth the time what cam would anyone suggest. I also know that I would have to send my chip to Howell to have it reprogramed.
