HELP! emmisions equipment
I am looking for help in figuring out the original emmisions equipment provided with the 1973 Ford Ranchero. I have the vin.# and all tag codes. The engine is the 351 Cleveland, 2v.
I know that the vehicle has a PCV valve, a charcoal canister and one VSV. I don't know if it had an air pump and I don't have an emmisions schematic that shows me how to connect the charcoal canister and the VSV. Any help is greatly appreciated. Thanks, Lee

well...why are you smoging a 73? Unless theres some place that requires all vehicles smoged, you shouldnt need to on a 73. Emmisions equipment wasnt made big untill 74, thats when it was put into all vehicles. That pvc should be all you have, the charcol chanaster suprises me as it is. You sure its a 73?

Yes, it is a '73. In Missouri all vehicles 1971 and newer require a test. No idle test but it is a dyno test at various speeds.
The vehicle in question is a 1973 Ranchero, 351c 2V, .030 over (357 cu. in.). Engine has been built but the remainder, except paint, is stock. 3.00 rear end, FMX trannie. I have not tried to test a vehicle of this age in MO. So I want to be prepared if they try to tell me it "needs" components that were'nt on it from the factory. Thanks, Lee

intresting, I thought here in CA we had the hardest laws. Well to my knowlage no thhere wasnt an air pump (the smog pump). There would be a mounting spot for it on the block, just like the alternator and power stearing pump. If you have a 2bbl you shouldnt have a problem mostlikley unless they are really harsh on it.

Terminal Velocity,
Thanks for the input. I had it smogged yesterday and it passed faster than anything else i've done. In CA you guys have a start and idle test in addition to a rolling test on the dyno I believe. Here in MO we just have a dyno test following various speeds and shift patterns. What I found out yesterday, for anyone new to older vehicles (like me) and going through this in MO is that anything pre-1980 they just run at idle, test idle engine speed and sniff at idle. No problem to pass unless your puking out smoke. Once again, thanks Terminal Velocity. I'll probably have other questions as I get this back into daily driver shape and beef up the 351c some (aussie heads, x-pipe, etc) Lee

sure, anytime
If you need advice on a setup I can help ya out, and there are some here on AF who know tons especally here in the ford forum. If you need anything else [email protected] is my mail And here in ca, anything 74+ needs idle, roling, various load conditions, etc, so unless its perfect or newer, it fails.
