Hello all. I'm well into tearing apart my '82 Cherokee for a full restoration. I've rebuilt the transfer case so far, and have started stripping everything down for the body work and painting.
I will be rebuilding the 727 and the 360, if only to get it to stop puking fluid all over my floor. It's never run under it's own power for me.
(I'll be posting a build thread when I get far enough along)
So, when I've started studying the engine, all the emissions stuff and vacuum hosing is downright depressing. I can't believe all this stuff works in harmony to produce a good running machine. I'm lucky that I believe it's all 100% stock right now, and nothing has been removed. Except for the mech fuel pump was taken out and there's an electric now.
I'm trying to hack out a master plan for the engine & driveline, and I need to know what everybody's experiences are with emissions testing on their FSJ.
I have to pass Denver area emissions. In looking at the Clean Air Colorado website, the 1982 are the 1st year for rolling on the dyno tests. All I can find for limits are these:
1982 & Newer Light-Duty Passenger Vehicle Limits
Year CO HC NOx
1982 45.0 3.5 5.0
1982 & Newer Light-Duty Truck Limits
Year CO HC NOx
1982 65.0 6.0 6.0
I'm assuming a FSJ would be a light duty truck? I think a good running engine would pass those limits without 80% of the crap that's on the engine now.
Here's my questions:
1) If everything is kosher (I rebuild the carb, replace all the vacuum hoses, do the ignition upgrades, etc) does this setup with all the stock emissions work well?
2) I will keep the catalytic converter obviously, and the air pump. Can I get a non-EGR manifold like an Edelbrock and a Holley 4V and still pass emissions? What if any of these vacuum hoses, air cleaner lid vacuum traps, charcoal canister and other stuff can I get rid of to simplify everthing? Can I meet those standards with aftermarket parts?
I don't need to pull stuff off for the hell of it. If if works well I'll keep it, but....holy cow. What goes where?
Ideally, I'd like to go with a Holley 4v, a different manifold...and get rid of most of this stuff. Does anybody in the front range area know how far the emissions inspectors visually check under the hood, other than the obvious stuff like the CatConv and the air-pump?
Thanks for the help.
