This is by far the most amazing sounding jeep ive heard. Ok i have a 99 4.0, and i want it to sound like this. You spoke of a cam on earlier comments, can you tell me more about this? THanks, and thanks for putting this amazing sound into my life.
The cam is a COMP Cam model. I forget the exact lift and duration, but it was in their catalog as a 4x4 Xtreme. I called and asked for a lopey cam that would still be streetable and move the power curve lower in the RPM range.
Highly doubtful. Different architecture in the heads and exhaust designs. You may be better off finding a 4.0l in a boneyard for a few hundred bucks and swapping her over. I did have, for a short while a 2.8l Cherokee...and it was most defintely not worth the trouble of keeping it running. I had the same expirience with an S10 with the same motor, and my friends GMC S15.
if you really want your jeep to sound like that you can just cut the vacuum hose that goes to the map sensor. I did that on accident and it sounded like that but blew out black smoke. I don't think he did that tho:)
the old inline sixes were notorious for their monstrous amounts of torque. It's a shame Chrysler quit using the Inline 6 engines in the Jeeps. the last jeep to be sold with one was the Wrangler. Now they use that POS 3.7L
I had a 1979 Jeep J10 with the 258ci straight 6 through the 1980s that I had to junk out due to a large tree falling on it during a tornado. Engine mods done were an Offenshauser Intake with a Holley 4bbl carb. Split headers with 3 tubes into each set so was dual exhaust running into Cherry Bomb glass packs on the street. Under heavy acceleration sounded more like a P-51 Mustang WWII Fighter Plane racing down a runway more than anything else.. Fast.. Loud.. and Strong.
J10 was smallest of the J trucks, the half ton, since shes got a Dana 60 out back and a 44 up front, and has heavier duty half ton leafs, she just gets called the J10...It's not the size of the truck, its the capability
Wow I didnt mean to ruffle any feathers. You actually have closer to J-20 running gear, so why call it a J-10? Any way you slice it, that thing is a commanche, not a J-10. J-10s were full size based on the wagoneer design, commanches were built off of the mid size cherokee design.
Wow that sounds beautiful. A straight six sounding almost like a V8. I didn't know you could put the 4.0L heads on the 4.2. I'm taking out my carbed 4.2 and dropping a fuel injected 4.0 HO.
Where abouts would this motor be coming from?You said it's running a little rich and anything else?Please message me with everything and about how much you would want for it.Thank You!
The Motor in her now is an old 4.2 straight 6 from an older jeep, running no cats, no mufflers, its been bored over to 4.6, running old ford 302 pistons. The head is off of a newer 94 Jeep Cherokee H.O. When I drop the 390 in it, I'm figuring something in the neighborhood of 200-250 for the long block, without the exhaust. The trans is probably gonna be with it. It's the original trans. A Torque-Flight would be going in with the 390.
Yea, rich...when i swapped the 4.0l HO head to it, i had to swap it to fuel injection, im used to Carb'd cars or computer flashes on the injected ones...so since i cant find a shop or a chip to flash mine...im kinda stuck with the ECU trying to make its own program with the bore and stroke
its a 4.2l straight with a 4.0l HO head on it, and bored over by F&H machine with Ford 302 pistons. And a custom cam and crank assembly, The exhaust is a split Y pipe with just a set of end pipes on it.

Nice 258. Any mods other than the dual exhaust?
FYI thats a Commanche, not to be confused with a J10. Commanches are mid size pickups, J10s were full size pickups.
