Re: 91 olds cutlass calais 2.3 quad 4 info

if you have a W40, then you have 180hp, and a redline of either 6800, or 7000. If you have a W41, you have 190hp, and you have a redline of either 7000, or 7400. The main way you can tell the difference between a W40 and a W41 is the plate over the engine, pop the hood and look at the plate, if it is red and says W41, then you got one.
