Trinity CO27 is in my opinion the superior ROAR legal stock motor for on road touring cars.
As for the Spec I had great success with the REEDY 19 Spec motor (orange) but that was off-road, the track at willis is to small for mod.
I could not tell you anything about the brushes and springs for mod but as for upgrading the CO27 I highly recommend Putnam blue and green shunt brushes in combination with the red trinity springs. But just so you know this will not give you long term life as some other brush/spring combo but the performance will be at its peak. Also slot the brush face at a 45 degree angle
to raise the wattage and get even more bang for your buck and make sure the timing is set as far as the tab in the can will allow. If you want to get real technical you could polish the bushings and armature but unless your loosing the a main by one hundred thousands of a second, I wouldn't be to worried about it. The driver is what really matters.
