Gettin ready to order a set of Mad Dog Headers....They are going on a 383 68 Dart..I spent a little time on the phone with Mark earlier and he said that approx. 30-40 minute install should be about right.
We shall see...

I find it hard to believe that headers could be installed on ANYTHING in 30 to 40 minutes. Even on my Harley.
