Cool, glad to see you went with the hyd. roller valvetrain, I see you are using alloy rocker arms with billet holddowns on the shafts, nice! It should make gobs of lowend torque and still pull hard on the topend and make some nice HP numbers! It's gonna rev quick with the lightweight bob weight of the rotating assembly and have greater durability than a smaller 500 piston that has to run oil ring supports. Cant wait to see one of your videos of it in action.
