Well, I drove up to Clint's place (Hybrid455) on Saturday in between family events to listen to the rollover noise in his setup with a single mass flywheel. While the noise wasn't unbearable, it's definitely noticeable, both inside and outside the truck. I know that the noise can be different in every setup, but I'm leaning towards another dual mass setup just to keep things factory.
Looking at the SouthBend website, they list their dual mass kit as including a Valeo flywheel. Any other manufacturer to look at besides Valeo for the flywheel? Any other clutch to consider besides the southbend kit?
I had the trans out a few years ago to do the rear main, and recall it wasn't too bad except for having to remove the downpipe to get it out. I looked today, and may be able to sneak the trans out around the downpipe on my new Aurora 2000 turbo kit. Anything else to consider replacing while it's apart?

There are many different brands that make flywheels for these things. It's worth a call to
Ft Wayne Clutch Their products and customer service are second to none.
If you are ever going to be hauling heavy with that thing you *really* ought to reconsider the SMF. Aside from the obvious dampening action of the DMF, there is the lesser known overload protection device built into the thing, internally in the DMF . IT is designed to ONLY be used with a stock spec clutch. if you try to mate a heavy duty clutch of any kind up against a dmf, the overload protection device instantly becomes the weak link in the system and is destined for failure and a very inoppertune moment, when it fails, it will slip just as if your clutch had given out. i found this out the hard way when trying to wiggle my empty car hauler out onto the road one night and the thing broke loose and started slipping like crazy, and once they've slipped, that's it, game over, the thing will never hold properly again.
I'm not exactly sure why it's there, maybe to keep folks from trying to pull stumps and crack their crankshaft, I don't know, whatever the reason, it's a worthless pain in the neck that can leave you dead in the water.
If you plan on going with an advanced clutch surface, or towing heavy, there really is no other choice but a SMF . I fought it tooth and nail, I really wanted to keep the DMF but after that bit, never again, and with the 12 1/4" setup, all those extra springs keep the thing so quiet, I really haven't had any noise to complain about.
Even though it's a heavier wt, it's a synthetic so it flows better when cold, it doesn't get all thick and gooey like the dino oil that was in the thing before, so no worries
. I think I will try the motor oil and see what happens.
