To get the most bang for your buck, get a cam. Headers will give your more for your money than ported manifolds will, especially with a cam.

thanks for the info. my buddy in the TCCOA said roughly the same thing. what'* the most aggressive combo of cam/rockers that can be used with stock heads?

I would have to say the XP cam from ZZP with adj. 1.6:1 rockers, or the Intense S1x cam with the rockers.

Ya, that'* were I am right now.
Torn between going for a cam or just going for the 1.9 rockers.
If I go for the rockers now then they are throw away for the cam where the max rocker ratio is 1.7.

Rogue - why did you go with the 1.6 ratio ?? What head work would be required to go to 1.7 ratio ?

The cam is really big bucks when you consider all the additional hardware.
Adjustable rockers, springs, pushrods, retainers, lifters, timing chain, gasket set and PCM upgrade.

......it'* still on my wishlist.

I was just on CGP browsing around, and I was looking at some of the times people were putting down, and the mods they were using. I've seen some people running high 12'* with an IC, 2.8", 1.9'*, opened exhaust, PCM, and a CAI. This seems like a good combination. Even though the Bonneville is a tad heavier, you would still be running times similar to this without ever touching a cam. So even if you have 1.9'* already, your next step would be to go with an IC ... however, your trans may not like it.

I would say save your money and do the cam, then the IC. That 3.4 pulley should keep you satisfied for awhile.

Wont you need headers before an IC? I thought you would get massive boost stack w/o them.

Not neccessarily. Joel'* GTP has an IC with stock manifolds and he'* seeing no KR (from last I understood) with a 3.0? pulley

I was going off what people here have done. I dont claim to know anything

I may as well lend my useless opinion. Cam will yeild the best results.. no matter what. If your cam is not in the best power range of the engine.. then you aren't making the most poewr. This is common knowledge. However, with the engine being mounted as it is. I have no clue how you could ever do the swap, without taking out the engine. When looking at my engine bay, even if I removed the washer fluid and coolant over flow bottles, there is still not enough room. I was just kinda wondering, would you have to remove the engine to swap cams?

The 1.9'* were way to much lift with the cam, so it was either back to stock size or get 1.7 adjustables and stage 2 heads (at least stage 2 required for the combo). didnt have the money for the heads so I got the 1.6. If you do rockers you should do the springs, retainers, and rods anyway, the only additional thing you would need with a cam is the timing chain and the cost of the cam/timing chain is about the same as rockers.

We changed the cam in my car without taking out the engine. It IS possible for the 00 year and I would assume for at least the 96-99.

You drop the passenger side of the engine cradle enough to slide the cam out the wheel well.
