What rear end gears?
I have an 88 formula 350 with 3.27 posi in the rear currently and I was wondering which gears would benefit me the most in the 1/4 mile. Mods are in my sig.

Kevin:
Why do you say the 3.70s are noisy? Depending on the brand and how they are setup can cause them to be noisy but not all should be that way. What kind of gears were you running?

Re: What rear end gears?
Sorry to bring this back up, but I am able to get rear end gears and what is a good price for a set, and what gears should I get? I looked on ebay and they have a few. Also, what am I looking for? 9 bolt... is that all that matters or are there more details?

Re: What rear end gears?
Lot of gear sets are available, but you have a BW 9-bolt rear which was discontinued by GM in 1989. So very few aftermaket parts are out there for this rear. NO 10-bolt parts are intrtchangeable with the 9-bolt.

Re: What rear end gears?
Probably. It takes a 7.75 inch ring gear. I have some link on my computer at home for good places to buy gears for this thing. I'll post them if I remember. I think all I could ever find was 3.70 ratio and they were around $200.

Re: What rear end gears?
Here are some link to site that have gears for the 9 bolt. I have not purchased from these sites but the prices seem reasonable. The only ratio available from these sites is 3.70

Not sure if they have gears but they do have parts for the 9 bolt.

Re: What rear end gears?
no only 9 bolt gears are 3.70s. 3.73's are for 10 bolts and other rear ends.
but i'd recommend 3.70s for your combo. your setup with that superam will love it. i have 3.42's in my 10bolt and my HSR/L98 combo. it makes peak power at 5050rpms, and i cross the line near 4500 or so. i need more gear and 3.73's would be best.
reider racing has the 3.70 gears with install kit needed (new bearings and such) for $299 last time i checked
