M189 "Big Six" Motor
So I lucked up... I purchased 4 W111 for $3k along with a Bunch of extra parts including 4 motors and 3 trannys one of the cars is a 66 250se that has an all aluminium M189 3.0 in it (the green one). This motor has an extra free spining wheel on the back of the harmonic balancer that spins for a few seconds after the engine shuts down. but when you rev the motor it majkes a sound as if its binding or some bearings are worn does anyone have any info on this thing? i can post pic if needed.
