help with 270 flywheel. I have some 235 and gmc parts mixed and I need a gmc 270 flywheel. So I find one in my pile its got 1/2 holes spaced 2" for the flywheel to crank mount. It takes an 11" disc and has B38663-5 cast into it. Now the ring gear has 168 teeth, i'm almost 100% that this is a GMC and not CHEVY. but is it 6 volt or 12 volt.
THANKS JD
