Is an aluminum flywheel worth the added expense? I am currently doing a full rebuild of the 350sb in my 67 and am building the engine to approx 420 hp. How much difference does it really make? Are there warping issues to contend with down the road? I am using a Centerforce II clutch.

 

It depends on you and what you want. A lighter spinning assembly means less horse power eaten by the engine itself. So more power to the wheels. The down side is a heavier spinning assembly means more power is stored when you rev the motor. So at launch you will have more torque coming out of the hole.

We ran aluminmum fly wheels on out circle track car along with aluminum Drive shafts. Not all Alumi fly wheels are equal. You want a nice thick steel insert to avoid warpage. So buy a name brand you trust. Another issue with this setup is time. If the car sits a lot you can get a reaction between the steel and aluminumum. This can slow down the transfer of heat. I am not talking one or two years but if this clutch sees little driving in say ten years it could start to show a problem.

 

I just bought a ram billet/steel flywheel off Jegs and it was only 340 I believe for my car. Not to bad a price for what it can do for you.

 

It depends on you...

 

thanks for the help, I will be sticking to the iron version for now.
