1973 Mustang – Project SportsRoof – Compression Test Part I

I’ve done all the clean up and all the adjustments necessary to get a good reading on the health of the ’72 351C engine in my 1973 Mustang.

The next step is to check the compression.

First up was to warm the car a bit and then pull the plugs.

Here’s what the plugs looked like:


A very handy device to have is a remote starter (it keeps you from having to run back the cockpit and turning the key).  Just clip on to the positive terminal and S terminal on the starter rely and push the button.


The left side Cylinders 1-4.

They shaped up like this:

1 – 130

2 – 25, 35, 60, 90 (Fail!!!)

3 – 140

4 – 135

Here are the videos:


No doubt cylinder #2 has some issue.

Other bank coming up in the next post.

Thanks for reading.

    I’ll bet #1 and #2 are burnt exhaust valves. If you wet test nothing will change. Send ’em to the spa…:) The cost will be pretty low and they’ll regrind them all.

Let me hear from you!!! Drop a note!!
