99 Camaro z28 Need help with picking a gear Hello everyone. I have a 99 Camaro with a mild hot cam, long tube headers, ls6 intake and ported 80mm throttle body. The problem I'm having is choosing a gear and stall because I have 22" rims on my car. Guys I know you don't like the big rims but please help. This is an everyday driver but I would love to come out the whole and smoke these 22s

the reason most people into performance cars frown on large wheels is they are heavier which diminishes every phase of performance: acceleration , braking , handling. Not to mention the heavier your rear wheels are the more prone to breakage your rear end will be.
I am not bringing this up to rag on you but to mention that this may affect which gear might help you the most if your committed to the big wheels compared to what others may find best- you may want to be more aggressive with gearing than someone similarly modded with more conventional (lighter) wheels would but A4 or M6 question needs to be answered first

With the Hot Cam, a 3200 stall TC will be plenty big. As far as rear gears with a A4(auto) transmission I'd go with 3.73 to help offset the heavier weight and larger overall diameter of the 22" wheel/tire package.
So what tire size are you running, a 235/30/22..?

He's was also asking about stall size so he has a A4 trans. Furthermore he's most likely running a very tall tire with the 22" wheels so they're probably around 27.6"or slightly taller which means he will need more gear than normal. 3.73 gears with 27.6" tires would be like 3.46 gears with a stock height 25.7" rear tires, and the slightly shorter gearing will make it easier to turn the heavier than normal wheel/tire combo. Anyway that's why I'd recommend going with 3.73 gears.

as for what stall buy quality not price cheap stalls are generally weaker unless the stall is mild and based off a stock convertor core , also most decent builders will offer one free restall and I see more people go conservative then send back to stall up than the other way around especially where your cammed go for a 4,000 stall and if its too much you could have it backed off to 3600. I have seen posts on here from guys that have had several stalls and a lot of times a conservative rated cheap stall feels looser than a quality stall with a high rating another reason to stick to the better brands , Yank , Vigilante , Circle D etc..

good catch , I missed that he was looking for stall also.The likely taller tire is a great point also. 3.90 has the same pinion size as 3.73 I recall seeing in posts - once you get to 4.10 or lower the pinion gear gets tiny and the ring gear gets real thin - more prone to breakage. Also you will need to know if your current gear is 2.73 or 3.23 because any gear you buy you will need to buy it specific to 2 or 3 series carrier , if you have 273's and buy 373 or 390 for a 2 series carrier the ring gear will be thicker/beefier than stock to fit the carrier - about the only performance advantage to 273's lol.
