I'd say that converter is wayyyyy too loose for that procharged engine,I bet you are loosing alot of ET with it,in fact I bet its creating alot of heat in it.
I bet your blowing right through the converter.
The gearing might be Ok with that 4.11 gear and 1.64 trans,but as you get stepping that thing up,I'll bet your going to need to change the rear gears as well,
If its going to be more of a street cruser you definatly want to change the gear
