The 3.3L/3.8L 60 degree V6 engines were designed to provide good torque over a broad range, reasonable fuel economy and long life. Their reputation over the years as versatile performers has been well-deserved, and they’re still doing a good job after nearly two years. Contributing Editor Doug Anderson explains the what’s, why’s and when’s of rebuilding the popular Mopar motor, giving valuable information you won’t find anywhere else in the industry.
The Duramax 6600 is considered one of the top performing diesels in the heavy-duty pickup truck market. Introduced in 2000, it is credited with bringing common rail diesel technology to the U.S. diesel pickup truck market. Yet, prior to its introduction, General Motors had virtually alienated customers from wanting its diesels. Contributing Editor Roy Berndt looks at the evolution of this engine and the things today’s engine rebuilders/remanufacturers need to understand.
Generating extra cubes via a stroker crank is a good solid technique to gain more torque even if nothing else is done to the engine. However, to get the best out of a stroker some other complementary moves can (and should) also be made. Stroker expert and engine guru David Vizard reveals some of these moves that can considerably enhance the build’s output and your reputation as an engine builder without adding to the overall cost of the build. If you’re looking for some other ideas, Dave Sutton also discusses stroker combinations that aren’t quite so mainstream.
