1970 Chevy Camaro RS Distributor, HEI, Racing, 8-Cylinder
- Mechanical Advance
- Better Throttle Response & More Power Than Points On Stock HEI
The Racing D.U.I. only draws 2 to 3 amps off of the battery, whereas spark box and point type systems drain 10 amps or more. The Racing D.U.I. Coil and the Dyna Module produce a long duration spark allowing plug gaps to be open up to .050"-.055". Magneto ignitions can only run .015"-.025" plug gap. Horsepower is gained because more fuel is burned on each piston stroke. Spark plugs stay cleaner longer.
