Have you seen the inside of the x7 rob?
Not 421 or 821 , way different exhaust, different intake timings, better carb , better piston, better front bearing, the 15009 crank haas even undergone some factory casted in timing changes, not so the same , even has better low end
I think you need one so you can play with it
