most economical 200hp to put on a v20 cc?

[cterrebonne]

200 hp range, i would stay 2 stroke. all the 200 4 strokes are obese and just look huge.
opti's will get the best fuel mileage, i would stay away from the fichts, unless you can find a DI or E-tec for cheap, and then the HPDI's are hit or miss.
