So far so good, running on a 93 octane tune. Drivability has been improved as has power. I'll try to get the owner on here to put in his .02 cents.

I want pictures and a clear video! I love it when people do the Stroker kits for the 4.0L!

I like to highlight various oddball builds I end up doing work on (either tuning or porting) for me to do an I6 , much less a stroker in a Jeep on 33's and 6" lift is pretty outside the norm. I think it's pretty cool. :jump:

I emailed the owner the link to the thread, looking for pics and video.

I will, at least, have some pics soon, maybe some vids. This 4.6 is running great thank to Ryan.

Which route? The stroker motor or the sct tuning?

Update to this thread....owner now has a wideband so we have been tuning WOT. His intake is a restriction so he is not achieving true WOT use...Other than that the truck appears to be running great. Says on dry asphalt, a WOT punch from a stop will smoke the heavy 33" retread tires for ~10 ft before hooking up. :) May be able to extract some more power yet with some more timing, due to the heavy retreads and the 500+ lbs extra the truck has the spark is very conservative.

What's the gear ratio in the axles?

Any idea of MPG yet?

4.56s. Owner has not said anything on mileage, but I just sent a msg to ask him about it.

Edit: Owner replied, said he hasn't really checked yet. Once we are finished I would expect a 1-2 mpg increase compared to before tuning, and comparable mileage to stock.
