gears
hey guys i have an 89' with the dana 36 performance 3.07 rear end and was wondering where i could buy a set of 3.42-3.45 ring and pinion set or should i just keep the 3.07's? thanks
also do anyone have the borla stinger exhaust on their car maybe with some hooker LT's?
do you like it? have any sound clips? thanks again

I just bought a set of gears from Merle at Exotic Muscle when I ordered my headers. I'm not sure what ratios he has in stock but he can help you out with the selection. I have an LT-1 and went with the 3.56

Gears, etc.
I have a '90 that had 3:07's. If yours is a daily driver don't change gears get a 2600-2800 TC. Great SOTP improvement. I had Borla Stinger with Hooker LT and the car sounded great all the time. In the cabin it wasn't as much fun. Switched to Corsa. Sorry, no sound clip.

The L98 doesn't like to rev high at all, so 3.45s would ruin most of it's low-end torque. A 2600 stall converter, or even 3000stall, would put you right into the torque peak and give you one hell of a fun time.
I have 3.07s right now but only the stock 2k stall, and when the L98 was still in it was pretty fun to play with. My powerband is taller now, so not as much fun but that can always be changed.
Just remember to make mods that will compliment your curve.

L98s do not require the rear gear that LT1s like. If you go lower than 3.07, you may get faster to 60, but after that you will be slower. It will also cost you gas mileage on the highway by raising your cruise RPM (similar to driving in 3rd gear now).
You could get the same effect by going to a higher stall TC, without any detriment.

I don't mean to hijack this thread, but I have a 1990 and was wondering about gears myself. I don't know whats currently on it but I wanted a bit more speed from 0 to 60, but if possible higher gear on the freeway for better gas mileage.
Changing out the first two gears in the transmission to a lower gear, and the last one to a higher one seems the way to go, but I have no idea if that is even possible.
Anyway, my main question is exactly how does the stall speed of the torque converter effect performance? I thought stall speed was the speed at which the TC locked itself up? I don't see how having a higher speed can make it faster at low rpms, wouldin't it be ineffecient to have the TC spinning and not be locked up?

A Stock L98 C4 at max HP RPM on a 700R4 will go 143mph in drive. How many stock L98's cross the finish line in the 1/4 at 143mph?

Definitely concur with a higher stall converter over gears. With a truck like peak torque at 3K something, a higher stall will allow your motor to stay closer to it peak torqu rating.
though with a 3.07 and today's gas prices, it'll be better to stick with increasing efficiency (heads, headers, n intake) than the gears.
