So I know the specification of the factory '73 U code 440, but what would you guys suggest as a mild step up in performance? Factory U code is
0.464" Exh. Valve Lift; 0.449" Int. Valve Lift; Hydraulic; (050) Duration at .050 Lobe Lift; 225 Exh.; 214 Int.; 115 Degrees Lobe Separation
A friend suggested a '70 426 Street Hemi Grind cam would be a good boost in performance.
