The place I used to work had two quality goals:
1.  Do it right the first time
2.  Continuous improvement

If you do it right the first time, how can you improve it? Never did
quite figure it out.

>     Bob, Mistral is listing the weight of the 20B conversion at 395 with radiators I believe. The 20B will produce IO 540 like HP though. The 13B done well can make almost 200HP without even P-porting. Most 13B's so far are about the same weight as a 360 with all the plumbing. Carefully setup the 13B NA engine shoould be lighter than a O-360, you just need to do a carefull engineering job.
