I have the TWM setup on a 460 motor. I had mine chromed and they look great. They were very easy to install and setup. The driveablilty has been supurb. Mine are the 58mm and you can see this setup by going to my engine builders web site at
www.badassracing.com
Go to the GAllery and scroll down left side to Mike's 66 Cobra.
If you have any questions, e-mail me.
Cheers,
Mike
