How Would You Build This Stroker?

from a piston and "parts off the shelf" point, I'd stick with the 4" crank. Stock rods wouldn't concern me in the least with this build. Haven't shopped for a build like this in years, but are their KB pistons that would work? They're cheap and not too heavy. Camshaft.... I'd go flat tappet, but that's just me.... gotta pull the valve covers and tinker once in awile just to feel alive!
