Lets try something different, lets say its a 408 - same gears etc and same heads.....is it possible to get 500HP with a DP intake and a less "piggy" cam?
If so..what cam would you suggest? (Duration and lift will do.....)
You deffinatyely can get there stroking it,i'd go with more gear though.. a dual plane will work great something along the lines of an Air Gap or performer rpm,heads properly preped,and i'm a big fan of Lunati voodoo series of cams,i'd suggest the 60404 .513/.533 lift...
