    Thumpr cam in Vortec 350?

    Can a Comp Cams Mutha Thumpr hydraulic roller be used in a Vortec small block still using fuel injection?

    I know the limitations of the heads, but aside from that. Can the computer be written/flashed to handle such a cam? It doesn't sound like the Thumper series cams are computer grinds.

    Ideally no. The Vortecs dont have enough fuel or head to support big cams. The stock heads can't handle over .450lift, and the stock injectors areonly good to 400hp. There are no other intake/injector combos, cept the Marine. Its $$$$ and a lotta work to make fit.
