Removing anti-pollution equipment

[mx916]

I am looking to clean up the engine bay of my 1974 Charger with a 360.  Im looking to remove as much of the anti-pollution stuff as possible.  Anyone have any issues after removal?  Any issues with passing inspection?  Thanks for any input!

Other than an OSAC valve, what anti-pollution equipment did a '74 have?

PCV valve and canister. Id also like to replace the crankcase breather with the type that doesn't route a hose back into the air cleaner.

The engine NEEDS a PCV system. The crankcase needs to have an escape route for the vapors and pressure. The better you evacuate the crankcase, the better the piston rings will seal. Simply route the PCV hose to a nipple on the intake manifold. The opposite valve cover should have a hose of some sort routed to the air cleaner. This isn't a bad thing. The cannister can be tossed but be sure that the steel vent line to the gas tank either runs to a vapor separator or is blocked off and a vented gas cap is used.

EGR, air pump, evap canister.

I'm with Kern on this one.  There is no good reason to reroute the breather from the air cleaner.  Now, if you have an oily filter there, guess what- it's time for a rebuild.  If your intake manifold has floor jets or an egr valve on the heat crossover, sure, you can delete it, make a block off plate.  However, if the carb is original, it's jetted and calibrated to go with all that. YMMV.
