114" knucklehead

3 13/16" bore x 5" stroke. 8" carrillo h-beam rods. Ross racing pistons. Roller rockers. Flathead power heads setup for dual carbs. Heads aren't ported, but the ports are a beautiful starting point with thin stem valves on the intake side. Still has a 1:1 rocker arm ratio, which really limits cam selection. Look at that cam, itty bitty base circles, it looks huge, but the lift is only .450" at the valves. The lifters are gonna live a rough life though. In my opinion the guy shoulda done it with shovelheads. Woulda been much faster, and the valvetrain woulda been easier on itself, but some guys just gotta have what they've gotta have.
