3.73 question

I was talking to someone today and telling them about getting my 3.73 gears installed soon. The person I was speaking with suggested that I stay with my 3.23's that I currently have. The person stated that I would most likely start to get walked on with the 3.73 gears (strictly talking about racing from a roll - not red light to red light). Something about not being able to downshift to 2nd and being out of my powerbad at that speed/rpm.

Any thoughts on that?

Thanks for that helpful hint. Next chance I get I will go right out and change my auto to a manual.

As far as drag racing, my 60 ft. times suffered for a short time after going from 2.73's to 3.73's. I just had to learn what the car liked with the new gears. Now my 60 ft. times are way better than before the swap.

From what I read previously, through tuning you need to adjust your shift tables, MPH shiftpoints, something like that. If you change your gears and don't adjust this/these, you will have some points where the car will be a hog.

I think I read this from jimmyblue. He seems to be very knowledgeable. Search for his posts in Tuning and Gears & Axles.
