Before you start making very many changes perfomance wise check this article out in the TECHINFO section. http://www.bonnevilleclub.com/techinfo/?article=52
I would get the O2 sensor changed also. Make sure the car is running top notch. If I did the conversion right it is pushing 250,000 miles, it has quite a few miles on it so be carefully.
As for pully size I will leave that for some one else I have never owned a SC engine before.

o2 sensors are pretty easy to change but they are around 20.00 at autozone for quality ones(I think it'* bosch). I'm pretty sure you might ask willwren about the pulley. I think he got one from pulleyboys or something like that.

NO BOSCH!!!! EVER! PLEASE! Do NOT use Bosch O2 sensors in a Bonneville.
Use OEM AC-Delco ONLY.
Crazy, check your email. I replied to you through my hangover fogged mind

You may be right. Yours is the only car running a Bosch that hasn't had a premature failure (that I can think of off the top of my head). I know half a dozen cars (probably all with EGR'*) that have failed them early. Mine went in 60 days, and Jr'* too, I think.
If this is true, to some extent, the 180 thermostat and extra tranny coolers would also have a bad effect on the Bosch units.

Thats odd...I thought bosch was pretty high quality and good besides their plugs(they burn way too hott!). Why would it decrease gas mileage over oem ones? :?:
