How much HP will it deliver?

Actually it seems to be a holley 850dp on top.
The camshaft has advertised duration 278/290. At .050" it is 222/234, lift is 0.467/0.494

Would be nice getting around 400hp =P~

Bought the engine as it is barely driven after rebuilding. The only thing I want todo is the cylinder head job and gasketmatching the edelbrock intake.
