With the rotor removed, the springs and weights were revealed. Before removing them, take note of the position of the weights. Some distributor weights are placed differently, depending on the application; HEI ignitions will spin either clockwise or counterclockwise. Be sure to refer to your instructions prior to pulling the weights. Next, we used a pair of needle-nose pliers to remove the springs along with the small E-clips. From there, we pried off the center-hub weight. | 
To get the vacuum canister off, we removed the small clip under the base of the rotor assembly. Again using a small screwdriver, we pulled off the vacuum canister. This part can be tricky, so take your time and manipulate the shaft around a bit until the canister is free to move. Using a flat-blade screwdriver, we pried the two ends apart to remove the canister. | 
Next, we rotated the shaft a bit to access the module where the new Flame-Thrower unit will rest. We used a small ratchet to loosen the nuts. Make sure to unplug the electrical connections. Don't worry about keeping the wires in order, as they can only be plugged one way. |
With all the vital components and circuitry removed, it was time to turn this raggedy HEI into a looker. A can of parts cleaner and a toothbrush removed the years of grime; the peace of mind knowing it was clean inside was worth the extra 20 minutes. From there, we taped off the shaft and the upper portion of the distributor and rattle-canned a quick coat of semi-gloss black. Take heed and do not paint the shaft, as this portion enters the engine. | 
The rebuild portion is a snap. We replaced the clip back down on the base of the rotor then screwed the vacuum canister into place. | 
To install the Flame-Thrower module, we first made all the necessary electrical connections, grounded it, and bolted the unit back into the distributor. |
We reinstalled the center weight with the two E-clips and added the supplied bushings to the outer weights. You'll find that three spring options are sent with this kit, and while we opted to go with the copper springs for ease of illustration, refer to the supplied chart to choose which will work for your application. | 
Once the weights and springs were installed, we could mount the new rotor assembly onto its perch, and since the rotor will only fit one way, we lined up the notch in the rotor cap to the shaft assembly and cinched it down. | 
We installed the new PerTronix cap, which also houses the coil, and by pushing down on the tabs with a screwdriver, we were able to lock the cap down. It's a tight fit, so take your time. That's all there is to it! CHP |
