1973 Mustang Sportsroof. Currently a work in progress!!!
Well I've gotten the heads back from being redone and installed. Now it's time to tackle vacuum system.

As I look at all the 'missing' hoses, I see some that were plugged and some with screws or bolts shoved in them. (Times like these I miss the simplicity of my 1970 Coupe).

So I'm looking for a diagrams for the 1972 352C that is currently in my 1973 Mustang.

Was there much of a difference between the two years as far as the vaccum systems?

Are there any that can be by passed?

It is vacuum assisted brakes so I can't impact that.

I need to replace all the hoses.

I also may eventually add the RAM Air to the car (I believe that only the 2V had the RAM AIR - not sure though). Any thing I should consider for that upgrade while I'm fixing the existing set up? (I believe the RAM Air had vacuum connections attached to the hood).

Thanks

Tim

1972 Mach 1,408 Stroker dyno tuned to 597 HP. She's really fun to drive.
Tim, Re: Ram Air... Take measurements. If you've changed the intake manifold you probably changed the height of the carb. I changed to an Edlebrock RPM and the Ram Air system won't fit. I think an older Edlebrock Torker will work but Edlebrock doesn't offer that manifold any longer. Fortunately I'll be able to make the Ram-Air (air cleaner portion) work on a 79 Ranchero with a hood scoop and I'm leaving the part that mounts to the hood and adapting a different breathing system to the Mustang. It won't be a true sealed Ram Air system but I will be able to get fresh cool air to the carb.
