In the current SCC review of the JWT S3 cams it lists the price of the cams as $560. Does that sound right? And how much is it for the 95-97 JWT ECU? Also curious if it costs anything other than shipping to have your JWT ECU retuned if say you decide to add the NOS kit later, or you get the ECU before the cams and then get the cams and need the ECU retuned (if that's even necessary when adding JWT cams, not sure if it is).

Also have read lots on cam installs. Those of you who have the SCC article (if you don't have this months issue I suggest you pick it up! ) it outlines the cam install very well, except I need some help clarifying some things. I understand removing the valve cover, zip typing the chain to the sprockets, then there's that wood wedge thing. In that picture on page 252, is he just showing kinda where the wedge would go but not have it inserted, or is that picture with it inserted/stuck in where it should be? Can't find the wood block stuck anywhere in subsequent pictures so it would seem it's stuck down there somewhere below the cam sprocket area. Next step seems to be to remove the cam sprocket bolts as shown in the second picture on page 252. Then you remove the bearing caps. Do the oil supply lines come out before you remove the bearing caps or after? Then there's the whole thrust bearing thing that tries to jam itself cuz of the valve springs. Maybe I should just get an FSM and that will explain the whole thing? I REALLY want to have a good understand of how to do a cam swap. I want to be able to do it in my head before I ever even think about getting JWT S3 cams cuz it's going to be ME doing with no one to help since there's no SE-R folks I know of in the area. Does the FSM do a great job of telling you all you need to know for a cam swap?

The JWT ECU that you order already has the program for the cams. SOmeone (Rob Cadle maybe?) posted that JWT found that the ECU tuned for the cams worked better with stock cams than the regular jwt ecu. When you order the ecu, just tell them that you plan on adding the S-3 cams, just in case. You need to have the ecu reprogrammed for nitrous. $560 sounds right, a group deal was setup with JWT for $500 + shipping.

The install sheet that comes with the JWT cams is really good. It will show you where to put the wood block.
When doing the cam sprocket bolts, loosen both of them, but only remove one at a time, not both. It is good to have a friend at this point. Those things are torqued to like 120 ft-lbs. And need to be torque that much on the re-install.
The oil supply lines are attached with the same bolts as the bearing caps (journals), so they come off together.
When bolting or unbolting the journals, make sure you follow the correct order and take small steps. It took me about 5 rounds before all the bolts were comepletely loose. Same thing, maybe longer, on the re-install.
Dont forget the moly-engine assembly lube and grey RTV sealant in the proper places.
I used a haynes manual. If you are going to buy a FSM anyway, might as well get it before the cam install, but I dont know whats in there.

I did the whole thing by myself.
Make sure you have a clean workspace and some clean cardboard to lay things out on so they can be re-installed in the same place.
