My trip to the track...

Well done a very enjoyable read and i'm assuming, your first foray into the 12's.
A cheap upgrade i did on my Dart was the 2" supersucker spacer, that netted me .15 and 1.5 mph and only cost me 60 dollars from Terry Walters performance but results can vary dependent on your combo.

Not my first foray into the 12s, just my first with a MOPAR. It is sad to think my '73 340 'Cuda and my 70 Challenger RT 383 never made it this far. They always got sold to support some family milestone before they reached this level. The last MOPAR I had was a 76 Aspen RT with a 360. That was another fun car to take to test and tune.

I am not sure I can fit a 2" spacer under my hood even with my drop base air cleaner, I will check it out though.
