Chevrolet inline-six could be found under the hood of almost everything from Biscaynes to trucks! In many cases these straight engines were pulled out in favour of a V8 but there are those who want to be different and stick with the six!
This distributor will help fans of the sixes gain more performance from their engines. The improved strength and trigger accuracy are benefits but the adjustable mechanical advance provides an easy way to tune the ignition timing to improve the overall performance of your engine.
