67 Dart 270...Project Old School
I took my Dart back to the shop that built my A500 transmission and they swapped in a non-lockup A518 valve body. They only had to ream out one hole in the A518 valve body for it to bolt into the A500. The overdrive now works correctly and turns off and on with the switch. The guys at the shop spent some extra time with me going on test drives to get the shift timing and feel to my liking. At this point I am a happy camper!
I will miss the first part of the Hot Rod Power tour at Madison Wisconsin, but I should be at the Champaign, IL stop. Champaign is my old stomping grounds back in the 80s and 90s. I will be at the Gateway stop as I live right outside St Louis. Hopefully I can make a few passes at the track and get some hard data to compare 904 versus A500. I keep hearing the A500 is 1-1.5 seconds slower then the 904. Mine should be a good test as the only thing that has changed is the transmission. Even the converter is the same for the A500 as the 904 since I converted to non-lockup.
