DYNO disaster ? Help

Good point. I would ditch the dyno and use track times to see improvement. There are alot of good suggestions for you in this thread. Take your time and do it right. Don't try to just throw parts in and expect results. It is all in the combination and intended use. There is a very fine line between having a streetable classic that runs good at the track.
Of course you could drop about 20G into a 6.1 hemi and drivetrain and solve all of your problems.:)

P.S. Prine how have you been doing? Glad to see you are still here. I may be picking up a 5.2 magnum to turbo in my 63 dart. I could sure use your knowledge to make it happen.:)
