Be careful, it's not a TANK engine<LOL>, but really looking forward to seeing what you are "puttering" on! I play with a lot of two stroke engines, small, light, powerful....never liked 4 strokes, except the blown ones.
Every single 4 stroke I own other than one bike and my lawnmower is either super or turbo charged.....mo power, always more!!
My understand from talking with the builders at one of the Tuning firms indicated that they see failures; in order, head bolts, crank insert bearings....as you go over 420BHP so just be careful.
No one here wants you to fail, Steve!!
