2.29 gear ratio

Anyone used these or currently have them?

My 79 Malibu 305/TH200 had them. Not much for off the line acceleration, but would run 70+MPH all day without breathing hard.

They're good highway gears, but I like the 3.08 in the Gutlass. They're not bad, but still not great for a launch. Are you looking to upgrade? The 2.93 Posi in the Roadmaster isn't bad either , but it could definitely stand to do better on the launch. Even the 3.27 Trac-Loc (FoMoCo LSD brand name) gears in our Crown Vic are still great on the highway. I hear the 3.55 T-L gears are a little worse though.

if nothing else, they're better than the 2:14 gears.... 😕

2.14s are what Lingenfelter put in the dual-turbo Bonneville Salt Flats Trans Am he fielded in the '80s.

I'd keep the 2.29s, add a Powertrax in place of the pinion gears if necessary and put a 700-R4 up front. First gear will feel more like 3.08s and your car will have loooooong legs on the freeway.

I have a 350/th350 combo so I expect a sluggish bottom. Powertrax is a definite.

I have the 2.14 running now (or at least when I could drive w/o snow everywhere). Even without O/D transmission, she cruises nicely on highway and county roads. Need wet pavement or some pebbles to slip a tire, though.

Did I mention that the Lingenfelter Trans Am hit 207 mph? I think the crew had to tape the tops of the door glass to the body because the airflow tried to suck them out of the car.

So you're telling me there's a chance.....
