I don't know why they stopped per se, but that 304 v8 wasn't exactly a powerhouse: 125hp by the end of its run. That's lame- especially for the amount of weight it carried.

They did,t ?? They just stop,t putting it in the Wrangler (CJ) . I really don,t see the need for a V-8 . More speed - more power - burn more gas ??

Govt. emissions and AMC was going down the tubes...CJ sales were slowly slumping.
Last year of the V8 was 1979. The V8 was so "smogged" it lost it's grunt, as did all the AMC engines (and all makes) of the era. The best years of the 304 were the early years...no smog pumps or "air injection system". My 1972 didn't even come from the factory with a cat. converter.

In essence, the V8 was put in for more torque, not speed. 245 @2500 rpm as compared to the I6 at 195.

i am sure if they was to make a v8 now it would have more power for those trails that you wish you would have more power to get up to and the new models should be better than the last although i am sure some would disagree since they don't like the jk models

I don't see jeep going through the trouble when its going to be less mpg. And I'm guessing 99% of wrangler owners will never need the power . Even on this forum were the minority that likes to take wranglers off road . Most stay on road . Sure a couple hundred offroaders might decide to get a wrangler just because they added a v8 option but that doesnt justify spending millions to develop it.

Now in 2015 when jeep makes a 6 door one ton wrangler maybe they'll add a v8

Would be nice to get a v8 again, but don't hold your breath. Nice thing is...I can idle through almost anything on the trail, and I actually save gas compared to all the other guys...plus, mine has been modded with a high performance cam, had the heads professionally done....here is what it sounds like. This was from JPFreek Mag last year when they had a guy, Ken, out on the Jeep Jamboree last June. He featured some footage of my CJ...

I have to say, fuel consumption should not be a factor. My Grand Cherokee Limited Hemi gets 18 mpg local and 22 highway...which is better than the I6 or V6 now in a jeep...and the GC is heavier.

AMC's straight six is undoubtful a excellent engine and with fuel injection and modern technology has made them much higher horsepower making them that much better.

The 304 is a nice torque engine even stock it puts out alot. As some have said having the engine allows you to not have to compensate for larger tires as much and run at lower rpm's. I will be chaning to 4.10's just so I can crawl better...not for power reasons.
I can run 55 mph in 5th gear below at around 1700 rpms and not feel like it is going to bog. Can everyone without a v8 say that same statement? I have 33" mud tires.

As far as gas mileage my mileage is very comparable to that of any other jeep. Your pushing a box down the road. Having a v8 made drink more gas but isn't working as hard makes it use less also...washes out.

Great video tarby...my cj sounds very similar...gotta love it rev'd high, throwing some mud!

It would be sweet if you get could a 6.0 hemi on a jk.....add a supercharger...that would be a camaro killer.

Nice thing too is when you show up at an event, you have the classic old school v8, and there are guys with Hemi conversions and big money rigs...and everyone comes over to your old rig and DROOLS...I have had guys with brand new JKs all tricked out and clean as hell get pi$$ed at me because everyone flocks to the old iron...I just say it is a thing of respect...lol...and love every minute of it...hahaha!!

I wasn't trying to insult anyone w/ the 304, but what did AMC (then Chrysler) expect? When it was introduced, the 304 had ~180hp. Last production year? 125. No one wants a neutered bull...

luckily, from all reports that new pentastar will be rocking 290hps. Not too shabby for a V6.

I'm not insulted. I've updated my 304 with modern electronics, carb and a little bigger cam and I am putting out well over 300 ft. lb torque and at least 250 hp...maybe closer to 300 hp.

Besides a afternoon of work and some side headers you can get rid of all that extra crap.

Something that hasn't been said is the oil shortage of '73/'74 probably played a role in eliminating v8. Think about what cars looked like in the mid to late 70's.....alot of small, weird stuff came out.

and nice job on pumping up the ol' 304. I'd kill for that kinda output in my 4.0

Emissions and Fuel Economy.
The V8's of the 80's sucked, anyway. If I'm going to be stuck with no power, I'd rather have no power from a lighter engine.
Why they can't at least put the 4.7L in the JK, I don't know.
