    MuscleTang mod project thread (1971 M-Mach 1)

    More power to everyone doing extensive restorations. I did the same on a 1969 GT. I recently bought a 1971 M-code Mach 1 that is 99% rust free and with original paint and interior. I have taken the interior out to check for rust and found none, and I have used a bore scope to check the inside of...

    Power Steering Gear Box

    Does anyone know what the difference is between the Saginaw power steering gear boxes tagged SPA AE that were used starting 1/2/73 and those used earlier tagged SPA S or U?

    Two Different Heads

    I meant to say 4V open chamber heads not 2V heads.

    Two Different Heads

    To wrap this up, I tracked down and talked to the engine rebuilder. He said the heads were the same and were closed chamber heads. I found on another thread that a 4* head would be an open chamber head if cast beginning in January 1971. Since my Mach 1 was assembled in October 1970 it couldn't...

    Two Different Heads

    Thanks for the info - I'll at least take a look at the date codes. It will be a few days and maybe a week before I can get to this, so a reply post may be a little late.

    Two Different Heads

    I recently initiated a thread regarding Ignition Timing Settings and received a number of great posts in reply. Today I took a close look at the markings on the heads of my 1971 M code engine and find that apparently one is an open chamber 4V head and the other is a closed chamber 4V head. This...

    Ignition Timing Settings

    Again thanks for all the help. I won't be doing any tuning until the weather warms as I live in the cold East and my car storage is unheated. I wanted to gather all the good info I could to be ready for tuning. Based on your comments, I may switch to an MSD system as I don't want to struggle to...

    Ignition Timing Settings

    Many thanks to all who posted replies. The info should be very helpful in setting up the ignition system (and carb). In response to questions - the distributor is stock, but I will soon be installing a Pertronix Plug n Play distributor with an Ignitor III system and with an adjustable vacuum can...
