A/F stays consistent at 12.4 up to about 5500 rpm and then drops slightly above that. Tranny is a GM Certa with about 5k on it. Convertor(2300 because its still a towing 4x4), servos and shift kit were done at the time of the engine swap. Kevlar band was added after the first dyno attempt smoked the stock band. Swap required Lingenfelter 58/24x module to work with the Gen III computer. Also, added American Racing LT 1 7/8 primaries and Efans for the swap.
