Cheep Cherokee returns and we do our first ever 4-wheel drive chassis dyno test to see what kind of power our stock 6 cylinder makes. Then, we'll show an inexpensive way to bore and stroke the engine to get more power out of Jeep's 4-liter straight-six.

Not quite. The tooling was so freaking worn out that QC on the blocks was horrendous and the emissions would never meet stricter standards. Very similar to the end run of the Ford 300 six. Having said that both were wonderfully simple torquey engines whose replacements were garbage. The 300 six was the best gas engine Ford ever made and the 4.0 mated the Aisin transmission really gave Jeep a good reputation for reliability.

And try installing a lower gears on the differential to get back to factory power with the tire size and a lower geared transfer case for off-road since it doesent have enough “power”

@electronicsworkbench 3 жыл бұрын

@@fre0nx675 Pretty much correct. The 0331 head also had smaller exhaust ports. Could not open them up since the casting was so thin. You could go a tad wider but not taller. Due to that, even a turbo won't do much to improve a hole that can't flow any more than it could. This is why the 7120 ('91-95) and 0630 ('96-99) heads are the most desirable. They will bolt on to the '00-01 blocks. 7120 only lacks the Siamese exhaust port for 3 and 4 as well as the locating dowels. Slightly different shape to the intake port which seems to be the most re-engineered part of the heads over the 5 million 4.0L engines that were produced. www.enginebuildermag.com/2004/10/not-those-jeeps-again-the-facts-about-4-0l-cylinder-heads/

Really, you guys can't even explain the relationship ship of the Crankpin to the centerline of the crankshaft. Using your explanation the stroker would wind up with almost 8 inches of stroke. Pretty impressive for a block that's about 9" from the crank centerline to the head face. Stroke is determined by the off set of the pin to the crankshaft centerline. And in case your interested the first strokers were actually built by AMC power train engineers during the mid to late 80s.

Always scratch my head when people talk about horsepower in the same sentence as an L6. Not what they do well....they make torque. LOTS of torque! Stroking it was the perfect idea. Assume if they want horses they're gonna have to get some better valves and MUCH stronger springs in there to deal with the RPMS. Doesn't matter though, once built, it'll climb trees even if it won't drag race. Talked a buddy of mine into building his 292 (C10) and turbo'ing it. Thanks to Powernation, no less.
