Help needed QUICK - 350 MCI versus Kawasaki 13hp - New cart (possibly)

[BrewCityMusic]

I'm almost done with the 2006 Workhorse I am building (373cc MCI Engine, originally a 350) and I just got the opportunity to sell it today for a really REALLY nice profit, the only cart I have found to replace it is a 2012 MPT with the Kawi 13hp though ... The problem is that I have never worked with the Kawi motors, are they as fast or faster than the 350's? I'd be doing a similar build to the current cart, 28deg clutch, short belt, 23's (only the new one is definitely going to be "Long Travel" instead of Spindle lift) and eventually 8:1 gears - I just don't see a lot of performance stuff for the 13's out there yet, anybody w experience that can help me decide what to do? Thanks!
