Light steel flywheels.
I see ram makes a 153 tooth steel flywheel, 2 piece seal internal balance only weighs 10lbs. I think i remember gkull saying one time he has a 168 steel 22 lb flywheel that sounds like what i need. I have a new 36 lb center force not going to use.

You have to think about the whole rotating assembly weight. Not just the flywheel. all the pulleys, damper, crankshaft..... So you need a smaller diameter damper...
10 pound I would worry about the terrific bending forces over time when you dump the clutch.

When I researched this I couldn’t find a steel flywheel less than about 22 lbs and the one I did find was just a 30+ lb flywheel that had been machined down, and the thinner flywheel was going to create clutch linkage geometry problems for me. I ended up using an aluminium flywheel with a steel insert that weighed in at about 17 lbs. It’s great but it does take a little getting used to. You end up riding the clutch a little more on takeoff and I wouldn’t use one with a stock engine. You need considerable torque to make up for the lightweight flywheel.

Drwet, I'm not a fan of adjustable pivot *****. I've had to play around setting them up on clients cars. I found the the GM long ball stud 1.78 inches works fine with all the light weight aluminum and steel flywheels.
I'm also a firm believer in SFI rated parts and blow proof bell housings. I've seen a drag car with a hole straight up through the wind shield. It could have thrown a chunk out at 10 o'clock and taken the guys feet off at the ankles.

I'm using one of these on my 355. That and a McLeod Super Street Pro 10.5" clutch. I weighed it before inatation and it was closer to 17 lbs. It's a street car with a RG non-OD trans with a 3.08 rear.
