This is the easiest to install, easiest to adjust CNC machined distributor you will find. Just drop in as you normally would, hook up the three wires, set the initial timing, run a vacuum line to the advance and you are ready to dial it in. Literally. The knob on the side allows you to change timing up or down 1/2 a degree at a time. Starts producing a super hot spark at 50 rpm for easy starting and keeps putting out through 10,000 rpm. It also has a small diameter cap to clear tight fit applications.
Cap has HEI-style terminals. Fits Small Block and Big Block Chevy V8.
