I am looking to find out what all of the ZZ4 owners are running for rear gears and what rpm, ballpark, with miles per hour.

Looking to upgrade, currently stock gears, to match well with my ZZ4, and looking for some advise.

All help is appreciated. Thanks

With the ZZ-4, even 3:08's are hard to lock up off the line. It's a great motor.

My sig picture shows what a zz4 is good for.... :D
I have 3.55s in mine and isnt too bad for street driving, but i cant ever just "drop the clutch"

As far as the mph and rpms # you can use this site to enter in ur gear ratios and what not and figure out which would be best...http://www.f-body.org/gears

Thanks for the web site.

Anybody else with the ZZ4 running any different ( other than stock ) gears?

I don't have a ZZ4, but mine is built to pretty near those specs/....and I"d say anything in the mid 3's is plenty, especially with no overdrive....
biggest thing I'd do is add o/drive...and to do that cheap...means automatic tranny....200 or 700r4.....but that depends on how much freeway driving you do with it, around town, it's not worth it....but if you cruise freeways, yeh, it is....

I got 3.36's in mine. I like it fine. You can grab a rollin' first gear like you would grab second in a five speed and it doesn't have to wind way out at highway speeds.

What he said! :yesnod: :yesnod:

3.31 - Anything lower and I'll just spin the rears. Plus these match my second gear to most of the mid-size autocross courses here in Texas.

I'm running 3.73 with a 700r, 2800 stall, 750 Holley vac secondaries, BFG 275x60x15. Best 1/4 12.82 at 104 mph going thru the traps at 5200 rpm,(right at the max hp). 1.69 60 foot time. My zz4 is stock 355 hp. The hot cam would probably pick up the top end. LOL

Again, thanks for all of the help and suggestions. Exactly what I was looking for.

I am in the process of changing my 3.08 to 3.90 on my 73 with ZZ4 w/hot cam. Presently running 13.83 @108 at an altitude of 4,300 feet. Traction is not a problem now and a strong launch is really hard on the clutch. Will post new ET in about a week.
