I just weighed my 13-B:     245 lbs.  It has complete  intake, complete
exhaust, factory coils, alternator.   No drive ,  radiator, or oil
cooler.    Those should put it at about 315 lbs. For comparison a friend
just weighed an 0-320 without exhaust system   at 279 lbs   I conclude
that the rotary is a little heavier than the 0-320 but comparable to an
0-360.       Jerry

What else did the O-320 have? Did it have the alternator?
Those stock Mazda coils are heavy. The GM one coil per plug are lighter.

Paul,
Not trying to nitpick, but I was under the impression that it is not a good
practice to mount the ignition coils on the engine due to vibration.  Loose
one coil and there goes half your horses.
