Inline six cylinder. I want to know why they stop making them. The Chevy, Ford, Chrysler and AMC sixes had to be the best motors ever built. I own two Jeep Cherokee's and both have the 4.0 inline six. If given the choice between a new titanium 20,000 rpm 800hp engine that only weighs 100 lbs and a slow speed low hp cast iron slant six with a one barrel carb the choice is easy. I'll take the cast iron.
