great point on the gearing. The R/T Auto LX cars run 2.65's. and they run mid 13's at 4300 lbs with 380 HP.... this thing should scoot!! I'm curious as to what the converter does with 800 less lbs...but lots of guys just pullout swap these w/o re-stalling, so curious as to what he reports! I've seen some diesel 8HP converters used in faster cars, much like some used to seek out the "6 cyl" converters on some of the GM stuff for higher stall. cool project.
