Jeep Straight Six Stroker Build: Big Power on a Budget
The Jeep straight six is one of the greatest engines of all time. But that doesn’t mean it can’t be improved. Newcomer Racing shows us how to put together a big power, naturally aspirated stroker 4.0 Jeep engine without spending big coin. The basic recipe is to use the block and connecting rods from a 4.0 Jeep with the longer stroke crank from a 4.2. Of course, there’s a lot more too it than that, and we’ll spell it out there.
Also, don’t forget to scroll down to the end of this post. Newcomer recently followed up with pics of the engine installed in a Cherokee and even results of a tuning session on a chassis dyno.
