What are your goals with the car first off. You could go back with a flat tappet if you don't have enough cash to do a roller but you'll need to pick up some ZDDP additive when you do an oil change. Is the cam flat or you just changing for more power?

my car had 110k on it. I would like something that will give me a lot of low end. I called comp cams and they only offer one choice for these engines. The spec they game me seeems way to big and it is listed for the 86-87 not the 84.

Well one of the decent choices out there is the Eldelbrock 204/214 cam. Good low and mid range and you can find it fairly easily. I've found them as low as $150 with lifters if you look around. The drawback is that it's a flat tappet cam and the current oil doesn't provide for proper lubrication of flat tappet cams. That's why I recomended the ZDDP additive which puts the zinc back in which protects the cam.

Here's the cam I was talking about. It's the same one as the Edlebrock cam and it's cheap.:)

Not to much over the factory one. It would work ok but you won't notice to much of a difference. There's lots to consider when chosing a cam. Since you're a HA car and it's a little under powered compared to the 86-87 cars you have to load the exhaust with more lift and duration to spool it better.

There are several companies to consider. And it doesn't have to cost a fortune, either. Many have used Lunatti cams in the past. I used a very inexpensive Erson grind in a budget hydraulic cam build for a motor that should easily have been a 10 second ride, and the owner got cold feet when the car touched 11.0. The car was never pushed any harder. Think the cam cost $89, but that was probably a decade ago.

I would suggest NOT looking for cams at Summit and Jegs, etc. Talk to the TR vendors. This is what they do. The catalog vendors only deal with what makes the most money, and don't care about Buick performance.

Right now, roller cams are the big thing. However, there is still knowledge about the standard cams. I suggest something around 206/206 or 208/208 @ .050" lift, not much larger, if your car will not be built up heavily. Liftwise, I'd suggest something around .420-.440. Perhaps err on the conservative side. And probably GM lifters, a new timing set, and a new timing set tensioner - unless you are going with a roller chain. Those eat tensioners and will cause you grief.

See http://www.gnttype.org/maint/quickref.html for the stock cam specs.

The 204/214 might work pretty decent on a hot air ... that turbo is a lot more restrictive than the intercooled cars and that might help a little with spool.

That Summit cam might be a bit "soggy" on the bottom end.
