Default Alum Flywheel

If you are going to mainly drive it on the street, I'd say no. You need the inertia of the flywheel to get the car moving.

I had an alum flywheel behind my 402. Really had to rev the engine up to get the car to move. After warping the flywheel faceplate and press plate, I had the stock flywheel zero balanced (stock and had never been checked) and reinstalled it. Been fine since and it takes off like stock with a Spec 3.

I used a 18lb steel behind my 454 and wish I would have stayed stock. But with the extra cubes, it's not too bad.

With a stock cam, should be less noticeable.

I agree. I just changed from an aluminum flywheel setup and went to an LS7 clutch, PP & FW. It's soooo much easier to drive around town and to be honest, I don't notice the drop in horsepower (if any). The quick revs was nice, but I'll trade it for the driveability anyday.

I would say no. I have driven both and I prefer the billet or heavier flywheel. Its easier to drive and the rpms dont drop as much, between shifts.

If you go with the LS7 clutch, which would be great at your power level, it is a heavy pressure plate and disc, so the lightweight Fidanza aluminum flywheel, part no. 198171, would be a good choice to go with the LS7.

You can put this combination right into your F-body, no sweat.

I like my SLP billet steel flywheel, I'm not sure if you can get them anymore though.

I felt a huge loss in power going from fidanza to the steel one. I tested it against a few of my buddys car and with the light flywheel i would put about a half car a gear easy and when i switched we were dead even
