Jerry, what is the advantage of going this route vs. using a 250 or 292 dampener?
The belt alignment won't be as good on the later-model 6 cylinder dampers, IMHO. I believe the 250 damper needs some pretty extensive machining to make it line up, and the 292 is a massive cast iron thing that might have clearance problems with some motor mounts and/or radiators.
Denny and I have these kinds of discussions all the time- - - -I enjoy locking horns with him, and I believe he participates in our conversations with the same sort of good nature. No offense intended!
