Triple disk clutch for 66 170 /6

One cheap and easy thing to do is have your stock flywheel lightened up some with a back cut. Sorry don't know much about slant clutches.

One thing though Mike is if you don't have a lot of down low power it may be a good thing to keep a little weight in that area. Don't know if you seen this thread or not but we talked about that some here.http://www.forabodiesonly.com/mopar/showthread.php?t=96080&highlight=aluminium+flywheel
