Great points and thanks for the shout out. One thing to note, the NP231J is rated higher than the AX15. We put them behind V8 power all the time without any issue. For heavily built V8's, extreme offroad builds, etc. it may not be a good option but for the majority of people using the Jeep in...

I appreciate the confidence but we don't actually get into the 4.2 or 4.0 much at all aside from maybe converting to a different transmission. I'm not much help on this one. Sorry guys. -Dustin

Agree with all this! Also, what axle ratio are you running? Will you do any kind of towing? Feel free to reach out and we can help guide you.

Will it fit? Probably. It will be very, very tight. You'll likely run into clearance issues with your accessories (A/C components, power steering pump, alternator, etc.) steering components, exhaust, firewall, etc. The engine is longer, wider, and heavier compared to a SBC. Keep in mind that...
