i priced out switching from my bmf 385 to full cnc big dukes either the sweet 16s or the kc pb 1803.with everything including,machine work hone ect and pushrods,new offset lifters,rockers ,intake.complete heads w/titainium valves,pistons,cost was over 15k.if your just gonna stick with cast intake single carb and wet sump its probably not much more than 100hp.just my take i still have the bmfs lol.
