wide ratio with 3.73

I've done some research and saw that people were saying that with a 3.73 the car would hit third in the quater and fall on it's face. but I was wonering since the car was so heavy would the difference be noticable at all. also I keep chewing up speedo gears. does anybody know what I need to change to keep this from happening. I know the driven gear needs to be changed but I think it is part of the shaft??? if so what do i need to buy??
?

thanks guys. think I'm gonna go with it. and see what happens. it can't get much worse. guess I'm gonna get ratchet type sprags and good clutches and hope for the best

Just out of curiosity, have you dyno'd your current setup?

yeah I have, chris tutten did the tuning for me. I can't remember the numbers but I'm thinking it was like 278 rwhp off the spray

just got it back and it's a different car. not sluggish out of the hole at all anymore. good pick up. can't wait to get it tuned and see what the difference is at the track

ok guys got a whole new set of problems. went to have the car tuned and driveability is 110% better. also the converter locks up perfect and shifts are firm and crisp. cant seem to make a pull on the dyno though. it wants to down shift let go or unlock at about 4500rpm at WOT. even locking it in 3rd by chip raising shift point and lowering down shift point does no good it still does it. bear in mind that the I have the wrong shaft to correctly drive the white spedo gear. could this be a problem??? the speedo is still off about 7-10 mph. I'm beating my head into the wall trying to figure this out myself. or could I need a bigger servo. any advice/ideas would be a great help.

I've got a template that will keep it locked on the dyno:
