Thinking about 3.73s
Interesting point of view Tim, I like the way you think. Added cost is going to be getting my speedo gears changed on the tail shaft, stupid 93s

Anyways, do the gears. There's some place here in MN that makes new tailshaft gears. I'm sure they already know what ratio to use for 93 Birds.
The spray helps TREMENDOUSLY to overcome undergearing.
Lots of gear is used to keep you in your powerband on NA applications,
while spray shoots you right into your powerband.
If you're spraying you are in your powerband period.

I think hes onto something...I have 4.10s NA with a small convertor...no spray in the near future...just dont count on any highway races
Just trying to make sure you consider everything.
I have even pushed 150 with the 4.10s.
The 3.73's would help your car out.
