I just picked up some raceseng roller rockers off Bob's and a billet intake off ebay, 34mm Mikuni, I have new 5/16 pushrods from a previous project... slowly gathering parts... I'm leaning towards staying with a stock flywheel with charging/lighting coils...the engine will never be free revved to the point of exploding it, stock flywheels don't scare me plus the weight helps with carry over....I will run a dipper rod since the engine will be mounted on an angle on the stock 340 engine mount that will be redrilled for the gx440 because of clearance issues with trying to mount the engine flat..
