Don't throw out those 3.73's, within a week you will be trying to put them back in.

With no heads the car will feel like a slug if you go down to 3.27's.
3.55's aren't worth the work to switch from 3.73's, so your options are limited.

I agree, ...with the 3.27`s in my 98 GT, you had to slip the clutch to get it to move. I swamped in a set of 3.90`s and the tach only went up 500 Rpms at 75 mph. My 05 has 4.10`s and as a musclecar, 2500 ROMs ain`t squat when you look at the infamous 69 Boss 302 with a 3 SPD auto or 4 SPD with factory 4.10s.......redline is at 6k or above, don't get ricer phobia.

The 69's weren't that fast and as far as rpms heck they prob didnt know any better. Ricer phobia, sh!t man the 4 bangers spin more rpms than anybody. Oh and she's a slug now w the 3.73s not much if any faster than w the 2.73s. If it had a 6 spd like the GM's of the day it'd be more enjoyable maybe

My Corolla beater tachs 2500± on the highway and if you bump off the OD, it jumps to 3500......its an auto and will shift 20 times in 5 miles trying to find a sweet spot. It loves 90 mph though where the rpms are up......which just encourages drivers to speed.

It really does come down to how you plan to use the car....

I'm feeling you on the 3:27s though.

When I first got my GT 5spd I had plans to throw in 3:73's, but kept putting it off. Now, I think I'm going to just leave in the stockers. I live on long flat ground anyway, and plan to use the car for long top-back rides. If I need to get-up-and-go, I'll just drop a gear or two and make it happen. I thinks that's where the OP is headed...

Feeling even worse is only part of it. The car isn't necessarily much slower with 3.27's, but it sure as hell feels like it.
And wait until you feel what it's like to try and get the car sideways or do a little tire burning.
Your gear swap is going to punish the clutch.

Not much sideways driving these days my man, I'm 31 not 16. The 3.27 or 3.331's gotta be better than the 2.73's that my dad had in the car for 14 years or so

Lower gearing just means you'll have to add HP. Easily solved problem

Gas mileage is not a concern.

My car is a weekend cruiser. I don't drag race it, or speed around. I like getting on the highway without feeling like I need to always be in 5th gear. I also hate shifting to 3rd and 4th just to drive down a road with a 50 MPH speed limit.

Just seems like for cruising around, a taller gear is preferred

Are we showing our age:zzz:

I'll be 100 years old and still will want to get it sideways now and then However, I do remember a few occasions of the blue-lights in my rearview mirror that have brought on a bit of gray hair aging.... $$$$$

I do a little fooling around pretty much every time i take the car out. As i have gotten older i just pick safer places to do it. As opposed to my younger days, where i always thought it was ok.

Might as well be a camry if you are going to drive it like an old lady.
