The starter is one of those pieces you never really think about upgrading until it fails on you. In this case, for our '67 convertible, we're planning on a T5 swap as well as a few other upgrades, so now's a perfect time to upgrade to a high- performance starter from Power Master.

Power Master is serious about the performance of the XS torque starters, so much so that every one of their starters comes with one of these dyno sheets showing you actual performance the starter put out. They also use the smallest chassis possible and their Infi-clock system allows turning in the mounting bracket, making it much easier to install in your Mustang.

The XS torque starter's going to come with two terminals mounted on it. If you're installing one of these in your early Mustang like we are, you'll want a jumper between these two since you're using a single wire with an external starter solanoid for your classic Mustang.

For this installation you'll need a jack and jack stands or lift, 3/8th ratchet, 12-inch extension, 9/16th socket, 1/4-inch ratchet, 9/32nd socket, crimping tool, wire strippers and safety glasses. The bottom bolt is pretty easy to get to; the top one we're going to have to use an extension or a swivel of some sort. The header is going to make it a little bit harder; you should be able to get it off though.

You've got to remove the wire. Since our early Mustang has an external starter solanoid, you'll want to make a jumper to go between the two terminals on the starter. You connect the starter to the starter wire before you put it up in to place. You'll want to get this connection snug; you don't want to overtighten it. Now I can put our starter up in to place.

Once our starter is bolted and the wires are connected, we're ready to test it! Our Power Master starter had no problems with our stock 289 and is strong enough for any motor we put in, in the future. Installation, figure 45 minutes to an hour. You'll be back on the road in no time.
