going through some pics found this made it from scratch, was wicked fast ported the head strong valve springs put a 390 carb , fuel pump,tossed the governer thing went 100kmh easy
Careful, at around 5500rpm the rod will let itself through the case on those chinese 6.5's. Ask me how I found out. Usually the valves float before that, but if you've got stiffer springs that's the next thing to go.
