And for reference, a Corvair engine fully built (including exhaust and
lightweight carb, alternator, etc) will weigh about 245 pounds, so an
O-320 is not a huge leap from a weight standpoint. I'm pretty sure KRs
have been built using them, perhaps Roger Baalman's for example, which
incorporates one extra 14" bay to the rear (more than the KR2S plans
call for). This not only helps fix the CG, but makes it a more stable
airplane. This comes pretty close to compensating for the extra
weight, and some have even added 2" in front of the main spar for extra
leg room. If power level of the O-320 is similar to the Corvair (110hp
- 120 hp), the extra boost is quite impressive, and the fuel burn was
substantially less than an O-200! There are several Corvair powered KRs
out there, with few complaints that I know of, once we fixed the broken
crank issue with the "front bearing" that VW flyers adopted decades ago.
