Gears
I would like to know if swapping from 3:45's to 3:73's would result in significant top end loss?
Thanks,
Joe B.

The top end limit of a c4 is not rpm limited but rather determined by horsepower. 3.73 gears will not hurt your top end and will probably help.

Thanks, now all I have to do is wait to see who wants to get rid of a pumpkin with 3:73's.

You might want to reconsider 4.10's for your LT4. I don't think you will see a big difference with the 3.73's.

I love my 4:10's and it's only an L-98

Don't bother with a gear swap unless you intend on going with 4:10's.
This is the ratio the LT-4 should have come with from the factory. I bought my LT-4 new and waited for 10 years before I finally made the change. I wish I had done it back in96'. Also you will run out of hp long before you run out of rpm at top speed. Gas mileage went down about 3mpg, but the car is much more fun and friendly in traffic to drive.

Here's a calculator you can use to determine rpm/mph with different gears.
