Hmm,my SC has the 2.97. I wonder what type of acceleration I would get with 3.06.

Well for how much money it would be to switch, you could get a lot more out of it.

Yep, i've already looked it up in my chilton. It says i'll need a special thread compound, and an adapter for a socket wrench to pull it out. How much is a new O2 sensor, where could i get the compound, and is it worth it to do it myself?

Hey guys,

I wend back to the salvage yard today to check out that tranny.... I was wrong in saying that it was a LeSabre. It'* actually a Park Avenue which is the same platform (correct me if i am wrong) I looked for the sticker with all the RPO codes on it, but the spare tire cover was out out of another car. At fist glance, it looked like a 3.33 ratio, but then i compared the vin on the sticker with that of the cat and they didnít match (the sticker was from a 3100 W body). Anyhow, this Buick had the bigger sway bar, tach and all the other "sporty" (for a Buick anyhow) stuff. Anybody have a guess as to what the ratio MIGHT be with the sportier option package? I am hoping for at least a 3.06. If it is, ill take it since it only has 74K on it and they want $65 for any tranny. BTW... there is a factory strut bar on a 95 Bonneville if anyone wants it.

well so much for my "sporty package" idea. The damn thing is a 2.84 But since the cahin ratio is 35/35, i can swap my diff and at least get a 3.06. Or i can get a diff out of a 3100 W body and end up with a 3.33.

I had the dealer check the ratio by looking up the VIN. It is a 2.84. Which means the chain ratio has to be 35/35. I was saying that ik can take a differential out of a 3100 W body and put it in the buick tranny and end up with a 3.33 overall ratio (which is very close to the stock 3.43 for the 3.4 DOHC)

Put in a 33/37 chain ratio and a 3.33 differential and you'll have 3.73 FDR. Now that is tire ripping :P
