What do staggered rear shocks mean?
#21
Not sure why the arguing going on here... The facts have been presented and are backed up in many car's on this site. For reference purposes, my 429 convertible came with A/C and the maximum and required 3:25 gears (it also has the trac-lok addition which was an option that the original purchaser would have checked off on the sales order). It also has the staggered rear shocks and competition suspension from the factory, everything that all of the legitimate documentation out there (much of which I have reviewed against countless car's over the year's as many other's here have as well...); confirms was available. There were some odd balls come off the assembly line, so some suspension set up's may have been added or missed, doesn't change the facts as stated...

All Mach 1s received the competition suspension, look in the 1971 Mustang Facts brochure, page C-8, under Functional, and on page C-11, Standard Equipment.

My sportroof, with a 351C 4V, came with the competition suspension.

At the time Ford was using York and Tecumseh AC compressors which were as good as any in the 70's. In fact the Tecumseh which had a cast iron housing was used in a lot of F600-F800 trucks with factory air.
The problem with the 3.91, 4.11, 4.30 cars was the extreme load imposed on the compressors when the sudden increase of extreme RPM's subjected them to stress they just were not engineered to handle. In fact in the 60's you could not get AC with any solid lifter engine since Ford knew how they were geared and how they would be driven. (High perf 289, 66 Police Interceptor 428, 427's and all Boss engines)

Hmmm this kinda throws a curve ball at my engine and rear end plans.  I was planning on running a solid flat tappet cam and 3:90 gears. Undecided Undecided  I don't plan on drag racing the car so routine high rpms wouldn't be an issue.

Don't let this scare you away from what you want to build. You just need to catch your breath and step away and think about how you are going to use your car. Show Queen, weekend cruiser, occasional driver, or a everyday ride makes a lot of difference. My mention about the solid lifter engines from Ford was in reference to a general non availability of AC and automatic trans since it was generally known how these engines would be used. Anyone that was willing to pay almost $500.00 for a 271/289 (High perf 289) over the 2bl 289 ($105) or 4bl 289 ($158) knew that it wasn't going to be used by Grandma to drive to the  ladies weekly sewing and knitting club.
My high school buddy owned a 70 Mercury Cyclone SCJ 429 with the 4.30 gear. A hour ride in it would have your ears ringing for the rest of the day. Was an absolute blast to drive something that felt like it was trying to push your eyeballs through the back of your head. The NO gas mileage aside, it was just a hot noisy ride where any trips were planned on where the gas stations were.
As David posted you can do as I did in my Mach 1 and just cut the AC off if you thought you were going to get  involved in some sort of red light "Confrontation". My 85 GT has a micro switch so when you go to WOT it opens the circuit to the field coil. Nice to have but also just as easy to flip the off switch.

Yeah, but it's like talking to a brick wall. 

Here's the 72 and 73 Mach 1 facts book page excerpts - Comp Suspension - STANDARD

73 front coil spring - no "63R" is the standard spring chart, only the HD - Compeition Suspension chart. 73 rear leaf listing from the MPC - notice there are only 2 "63R" listings - Mach 1's body code - both are "W/competition suspension". CS was optional on everything else except with the 250-6cyl.

Some of you guys need to fully understand what your reading. Where is it said that ALL mach's is entitled Comp Suspension. This sound like the lady selling her mustang... Saying, this is a 429 car , because my boyfriend told me so....Well I'm still only going to give you what this 73 H code title parts car is worth... Which reminds me tomorrow, I need too get more popcorn...

Time wasted, but here we go

Carefully read pg. 8 under( functional) not just the underline
The complete paragraph and note (351 4V and 429)

Still on pg. 8 under (Variable Ratio)
Vehicles equip with Comp. Suspension

Now pg. 11 under (Comp Suspension)
Again carefully read
Standard on (351 4V and up) Mach 1 Boss351 429 CJ or CJ-R

I standby my statement, the Mach 1 option was only eye candy
Mach 2V engines got standard suspensions, the same as 2V Sportsroof
The Comp Suspension option could be ordered for the 2V engines, but was not standard

The last pg. shone only state for 63R bodystyle
302 351 2b (with/ CS package) option available
351 4b (with/CS package)

It's all clear, and in writing. But then some folks only hear what they want too hear
Just like the lady selling the mustang

It's clear

63R body style 302 351

One more try,

Page C-8: The (351 4V and 429) refers to only the preceding "extra heavy-duty front stabilizer bar", not the entire sentence.


Page C-11: Nowhere does it say "Standard on (351 4V and up) Mach 1 Boss351 429 CJ or CJ-R"

Finally, go to page 15 of the 1971 Mustang Brochure and read under Standard Features - Mach 1, no confusing parentheses
