Carbon Fiber Dive shaft?

Upgrade to carbon fiber after you have the car sorted out. Once you've got the car to ET, run great and be dependable, then switch over to carbon fiber. If you want the car fast as possible, carbon fiber is the way to go.

But you must keep it away from any heat source. Small block Mopar Cars have limited area down there, so you have to watch it. A carbon fiber driveshaft will easily get ruined by header heat hitting it. Aluminum is a great option in this case, but most driveshaft shops make aluminum driveshafts very wide and won't fit standard driveshaft loops. Bring them your original driveshaft so they can measure and duplicate the width in aluminum. You are looking at a grand for an aluminum driveshaft.

Mancini makes the best steel Mopar driveshaft kits. They're not too heavy, but strong reliable kits.
You will have to measure your Car (YouTube) and take the kit to a local driveshaft shop. The driveshaft shop will be a big help in figuring out what ends you need to fit your rear end and trans. Stay away from the way over-priced billet stuf, Spicer 1350 or OEM is your best go.
SOLID U-JOINTS are a must for racing.
I don't recommend relying on your local driveshaft shop for a steel race driveshaft. They are interested in you "not coming back" and will build you a boat anchor. :BangHead:
