Racing motor, or street motor or are you looking at street racing. ither way, by my calculations 367 HP at 5,500 RPM done with Dyno 2000 ( dyno calculation program ) if you have low performance/ pocket ported heads ( I can't put in the 200 CC in specificly without flow ratings for the heads, I can only do guestimates ) you would be making 158 HP at 2,500 RPM, if you had a 3,500 stall, it would be better, because you would then have 258 HP at the 3,500
