FormulaMatt Posted February 1, 2007 Report Share Posted February 1, 2007 I think he meant the dyno question ("where should I take my car...") comes up all the time. I'm sure he will let you know though. Quote Link to comment Share on other sites More sharing options...

kirks5oh Posted February 2, 2007 Report Share Posted February 2, 2007 the convert probably weighs slightly more, and the aod is the killer. also, the rearend gears must also be taken into account. i had a '90 7-up lx convertible with aod and 2.73 gears in the rear---it was a complete dog in every sense of the word; even after i added pulleys, ram air, headers, and a catback (all parts i had left over from my '87). one more thing--if the '88 is a speed density car, which it probably is, then those cars were slightly quicker than their mass air counterparts--not by much, but enough.

Guest Removed Posted February 2, 2007 Report Share Posted February 2, 2007 t-5 cars are just plain faster. or go built aod with 4.10 or c-4 rollerized... lots of options.. Quote Link to comment Share on other sites More sharing options...
