I have used an aluminum flywheel on a Cobra before. This was on a 428FE. The differences were it needed a little more clutch when taking off from a dead stop and it seemed to let the engine rev a little more freely. On a light car, (unless money is a worry) I don't see any reason not to use one. It's less weight hanging off the back of the crankshaft.

As for clutches, stay away from puck style discs for the street. Use a good dual friction setup from McLeod or RAM. Stay away from Centerforce as a lot of guys have trouble with the weights.

I carry all of the above, and when I spec FE clutches for Cobras, I usually go with an 11" dual friction clutch disc. Depending on the horsepower and application, I'll either go with a diaphragm plate with an organic/ceramic disc, or a Long style plate with an organic/ceramic or ceramic/Kevlar disc.

You want to put the power to the ground without slippage, but you don't want something that will aggravate you to death on the street. However, one thing that guys don't understand is that you rarely can have your cake and eat it too. You can't have a clutch that will hold 650hp and actuate like a Honda. You can get into twin disc setups, but they're about twice the price of a single disc setup.

I have a McLeod clutch package that I use for 600-650hp Cobras with FE's. If you're interested, shoot me an email or PM.
