Exintake swap?
I read about an exintake swap in airbrush1's thread but didn't want to jack his, the mod consists of putting an exhaust cam in place of the intake cam. I did a search both here and on m.net and couldn't find much info.
Anyone wanna chime in? What would be a benefit of doing this? What would be a downfall if any?

The information is out there, but it's scattered and not well organized. In short you have to drill a locating hole in the cam gear so that the new exhaust cam is indexed correctly. 197.5* clockwise of the old hole is the right spot I think (from memory, go look it up).
This mod will increase lift and duration.

Indeed, and it needs to pay strict attention to the separation of solid lifter and hydraulic lifter motors. I'll contribute what I know later from my research. I have an extra 99' exhaust cam I'm gonna put in some time. When I do it I will definitely take lots of pics and do a writeup, as the info on this swap for a 99 is terrible.

That would be nice. But it probably won't happen. I'm waiting to put the cam in till I get rid of this miss I have. I need two more Millenia COPs and I will switch to COP in hopes of remedying my ignition miss. Car runs strong right now, but I know having a random miss is holding it back some. Besides I'll probably see higher than typical gains from a cam swap as I have a lot of head work done.

94-97's have the CAS driven off the exhaust side. Just cut the drive off an exhaust cam and install it in place of the old intake cams. Hydraulic lifters on this motor too.
99+ has solid lifters, and more aggressive cams.
I did my own head work.
EDIT: headwork cost me probably 200 tops. Would cost anybody I did it for 1K+
