I have 3.23 gears. I hear some guys saying I need 3.73 gear to match with that 3600 stall. I really didnt plan on swaping gear but idk.
I know swaping to 3.73 may give me .1 if any but im not worried about that. Im wondering what the driveability will be like 3.23 vs 3.73?

Well, it will make the converter tighter. Mine at the time was a 3200, I swapped from 3.23s to 3.73s and I saw about 500 rpm difference (lower) in light throttle accel. It took less rpm to get the car moving at light throttle. I also felt a SOTP increase during 2nd and 3rd gear pulls. 3.73s will make traction even harder to come by in first gear (which is steep anyway) and it will increase your cruise rpm by about 4-500 rpm give or take. I used to run 2000 rpm at 70 mph and now it runs about 2500. So, take the pluses with the minuses and make your decision on if the 3.73s are right for you.

I think im gonna have to just try out the 3600 with my stock 3.23s. If it ends up to be to loose then ill consider going 3.73. Thanks man!

I had it on 3.23 and it was fine. I actually liked how it felt with the 3.23's better than my 3.73's

What's the STR on your stall? I have a 3600(2.35 str) with stock gears(3.15 in my car) and it's not loose at all, rides great around town.

Thanks for the reply. Why did you like it better?



str on ss3600 is 2.5.

I have 3.42 in mine, my car is also at least 200# heavier than the average fbody and it drives fine.

Although technically the converter was originally ordered for a GTO by a member here, so I'm not sure if Yank makes them custom to account for weight or not. I got it used.

I NEVER use this modo anywhere else really, BUT on a CONVERTER I seem to like them loose

Whats so funny that none of the inexperienced really gets is there really is no magic behind a converter. Its a mathematical thing. You plug numbers in (program, spreadsheet, formula, whatever), and you get an answer. You then insert said turbine angles into the converter to produce said rated stall speed. If one number (torque, hp, weight, whatever) is different, then your final calculations will change. A 3600 spec'd for one car may not be a 3600 in another car. However, I think the converter companies with the best rep feel the customers out and may bend the rules a little to make the customer happy. Who gives a **** if the converter is a 3300 or 3600, if it meets/exceeds the expectation of the customer, then your business grows and you prosper. I have never foot braked my 4k to get an idea of where it stalls, dont care to honestly. It feels right when driving it and that is what really matters.
