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

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.

Yes, the 0-320 did have an alternator and a 4" prop extension.   I don't
know about the  oil cooler.

Do  you know the weight of the GM coils.  If there is a significant
difference,  I will change if Tracy can be talked into making the
requisite modification to  the controller.    Jerry

Tracy knows I think. I don't have a set.
Here is a picture of them mounted on the Power Sport engine.
