Warthog Posted October 17, 2023 Posted October 17, 2023 Just trying to get some info from anyone that has stuffed an old school v8 in a comanche. Got a 327 and Thinkin real hard on putting it in my comanche. Doin a total ground up build and still doin suspension work at this stage. Got 3 builds goin and all of them are being set up very similar. Was gonna do the 4.0 strokers in em but the thought of a v8 really has my attention. Being they will be stick shift and carbed there’s no issues of computer mating or compatibility issues. I have a 3 core aluminum radiator of some company I bought for the build plus did the hood vents, not for cooling so much as I just dig the look. I’d stick with the ax15 and do the Novak bell housing so the rest is still standard so to speak. Was gonna do a 283 which I absolutely love! But a huge huge fan of the 327. And I got one free. Regardless I’d rebuild whatever engine I shove in there. Trust my work more than “it was running few years ago!”. Yes I’m goin carb and well aware of peoples views on fuel injection vs carbs. I like what I like and know what I know. Mainly just curious if anyone has stuffed an old school engine in an mj or xj? What issues did you have? Any help appreciated!
ghetdjc320 Posted October 17, 2023 Posted October 17, 2023 Checkout the epic threads. Many V8s stuck in there. Hood clearance is a challenge with tbi or carb.
H3ADBANG4L1F3 Posted October 17, 2023 Posted October 17, 2023 You can fit a number of different engines into a Comanche. I've got a 350 L98 in mine - though I didn't do the conversion myself. Lots of people put LS engines in them. Novak has a great article about it here: https://www.novak-adapt.com/knowledge/engines/swap-guides/chevy-buick-gm/xj-swap. I've also heard of another company, Overkill, that does LS swaps. You can find them here: https://www.overkillbydesign.com/shop/jeep-parts

Of course! Here she is! No A/C currently, plan to add one and delete the smog pump you see on the driver's side.

You may leave the smog air pump where it is, the A/C compressor actually replaces that idler assembly on the passenger side, if that's what that is...
fiatslug87 Posted October 18, 2023 Posted October 18, 2023 How about a 300+ HP 4-banger? Probably won’t have to worry about cooling.

I know I don't have to remove the smog pump, but I do want to. Like you said the A/C will go on the pass. side 50 minutes ago, derf said: What exhaust manifolds did you use?
