I want a motor like this.

400cu small block V8
Liquid cooled
Titanium crank and rods
Cast 12/1 pistons
Pressed Ball bearing bottom end
Precision balanced
Dry sump oiling
Twin turbo forced induction (not crankcase pressurized)
Reed valve intake system
Crank sensor ignition
Tuned exhaust
2 stroke :D


(No cam, timing chain, gears, valves, lifters, pushrods or rocker assembly.)

Multiply your average Honda CR250cc at a rounded off 50 HP and multiply that up to 400cu and see what you get.
