1971 351C 2V with AC Correct Concourse Hoses Help
#11
Aside from yours being a Grandé` and mine being a Mach 1, along with being different colors, and yours having A/C, our cars are pretty much the same. whistling

What I mean is: both are H-Code (351C-2V) w/FMX & 3.00:1 rear axle gears. My Marti Report looks very similar to yours.

I am always baffled when it comes to engines fitted to differant models. I have had this conversion before about engines. I still believe that fastbacks and Mach 1 should have been sold with bigger CJ engine and Grandé should have had H code engine. Just makes more sense to me.

I know what you mean - you hear the term "Mach 1" and think it's the upper-end of the performance spectrum... but in reality, a Mach 1 could have any of the V8 engines offered, from 302 through 429 SCJ (Super Cobra Jet).

In reality, the "Mach 1" models just have the flashier trim packages, since you could order pretty much any engine/transmission combination in any of the models.

Pegleg. the single and dual references are to the vacuum advance (the round device on the front of your distributor) that is held on by two screws. Depending on the build and calibration level of your engine, it could have either advance. If your distributor is the production installed unit, there should be an ID number on the housing. That will enable you to decode what you have. I have some illustrations of the two different advances and the location of the ID number.

Not sure if this issue is still in question or not?  Being late to the game I will contribute that the single or dual diaphragm is related to the distributor.  My all original November 71, H-code came with a dual diaphragm distributor installed.  There is a separate vacuum hose kit for the dual diaphragm versus the single and it has a little different routing diagram for the lines.
