For your described application I would suggest a solid tappet camshaft similar to this:

274°/288° duration @ 0.020 (advertised)
113°/116° lobe centerlines
238°/252° duration @ 0.050
36° Major Intensity
52° overlap
114.5° LSA

Such a cam will make peak BHP at approximately 3500 FPM mean piston speed, which is equivalent to 6000 rpm with a 3.500" stroke crankshaft. This complements the 4V cylinder heads. It will still rev as high as is "prudent" with an engine equipped with the factory connecting rods (~7000 rpm); but it will behave much better at lower rpm for street operation ... and with the Webers.

Food for thought.
