Keisler questions - actually flywheel?
I just bought the TKO600 with the .64 OD. Other options were scatter shield. I almost got the .82 OD and was going to go with a 3.73 or 3.90 rearend. But I decided to just get it going for now with my 4.11.
My question to all of you aftermarket tranny guys is:
Which is better the light weight billet steel or aluminum fly wheel?
The unofficial weights for the heavy duty 11 inch clutch were 40 lbs (billet Steel) 25 lbs light weight billet steel, and 20 lbs aluminum. I almost bought the aluminum, but I just paid the extra for the 25 pound steel.

Well, what is the car going to be used for? It'll be harder to get off the line with an alum. flywheel..... so if you're a drag racer, stick with the steel. If you're a road racer, go for the alum. There was just an article in the December issue of Vette magazine on this very topic. Good luck!

The steel will be bulletproof for sure, I don't trust aluminum, and doing what you do you can't go wrong, especially with the torque monster your running. Are you going to go with the gear change?? You'll have a hell of a top speed with 3:73's

Your gonna love the 5 speed TKO 
With his 4.10 rear end if he takes it to 6500RPM in 5th he will be going 196MPH, with my 3.08 at the same RPM I will be travelling 261MPH

As I understand it, lighter weight allows the motor to change rpm faster. My question would be why would you want the heavy fly wheel?

More inertia = more forgiving coming off a stop. Aluminum flywheels are great - but many racing organizations will not allow then - like Utah Salt Flats guys or SCTA. The lighter aluminum allows your car to pick up RPM faster - think coming out of a low speed corner! The light weight steel is a great choice - thats what we went with - and we are very happy with it.

Since www.smokemup.com went to pay per view I have not looked at any speed charts. One of these days it will get the speed test with 28 inch tall race tires. I have more power now than my old 383 that would turn 7000 in OD

All kidding aside, I'd go with a steel flywheel. Way, way stronger than aluminum. It will take a lot more abuse. Given your motor's output and your historic love of hard shifts, it is the way to go.
Does that thing come with an explosion-proof bell housing? If it doesn't I'd fab up something for the tranny tunnel or wrap it in a kevlar blanket. If that mother comes undone....oh, boy.

Well I'm not sure. Ram says it's cnc machined from billet steel. That means it started out as a solid chunk of steel. I know billet parts are capable of being of a higher strength than a forged part. It depends on the quality of steel it's made from, same would go for aluminum. Not all billet parts are created equal in strength. Some manufacturers describe their parts as "Forged (steel/aluminum) Billet", where others leave out "forged". I don't know but one thing is certain, I'm not a metallurgist so I may not know what the hell I'm talking about.

For an additional @ $900 I got the Lakewood SFI scatter shield bell housing, The 168 tooth billet steel light weight flywheel, and the 650 foot pound of TQ 11 inch super clutch.
The total price with petals and everything is $4748. Now all I need to do is get rid of my racing 700R4 that's been so good to me and recoup some money.
