To get a performance expectation based on reality search this site for info concerning your Crower camshaft in a 400 ( more popular build ) and adjust reported powerband RPMS by almost 500 more.... 350s of any brand really drop off in torque after idle with cams 20 degrees more than stock duration.. And because they are small engines to start with they are a bit handicapped to start with.
Even a 068 cam looses off idle power to a 066 / 067 / 254 cams... You get more top end power but what you gain there comes directly from off idle
