broken flywheel
went to the track today and i started the car up let it warm up and drove it around the track but i heard a noise that didn't sound right so i shut the car off took the valve covers off too see if i had a loose rocker or something all look good put the covers back on and try to start the it made a half turn and got a little smoke out the carb and that was it. so i thought my starter had went out but i had a friend hit the starter as i look at the starter it was spinning the converter and flywheel but not the engine the flywheel center had broken all the way around. can any body tell me what may have cause this. it was a new sfi flywheel don't know the brand bolted to sbc and powerglide.
