Some classic cars had a straight eight or fireball eight i think they called it in "rainman" the movie. Dodge viper and the ram trucks have a V10 option. Jaguar has a V12 but thats british and is less reliable than AMC.

To answer your question, I think it's pretty safe to say that any decent V8 is better all-around than an I-6 (although I do not mind my 258 at all and I'm not knocking straight-sixes before you guys jump all over me! ). My experience has always been with Chevy V8s--327, 350, & 427--and I give the 350 high marks for being so cheap because they are so plentiful. It's not uncommon to see remanufactured 350 long-blocks in the $1300 range, even less for short blocks, and I know Quadratec and 4wd Hardware want at least $1400-1800 for an equivalent 258 I-6. Also, a properly tuned small-block V8 can get just as good gas mileage as an I-6 if it isn't too modified. Heck, I'd even consider a 350 conversion for my jeep if the 258 ever dies. Anyway, that's my two cents. And you can just about forget finding a good straight-8 unless you have an abundance of 50s Pontiacs or Oldsmobiles lying around--you wouldn't want one anyway, it's incredibly big and not nearly as efficient for its size as later V8s.

Currently an '86 CJ-7 and a '77 CJ-7 Golden Eagle---#4 and 5 following a '01 Sahara, '90 Sahara, and '85 CJ-7....

I know its probably not what you meant, but back in the day (1910-1930ish) you could get anything inline. Even a 10 cylinder. That's a big freaking engine.

Just Sayin'

I-6 vs. V8 is always debateable <img border="0" title="" alt="[Wink]" src="wink.gif" />

I have always had the 258 for years, now my "new" toy has a '72 AMC 360. I like it so far in the few spins I took it around the neighborhood. I don't know whether i will like it all-over better than the 258, it'll take me some time to "experience" it once I get it on the road for good.

You can get a rebuilt 258 short block for about $650 and a long block for about $900 right at Pep Boys (Auto Zone is probably as cheap). I deal with 4WD and Quadratec on many things, but I think their rebuilt motor prices are higher than balls on a giraffe.

I took a Pep Boys Short Block (8 years ago) as a base for a performance motor. All I did to the short block was put in a Clifford Performance Mild Cam in place of the stock cam. After that, i went to town. I already had a head for it and had it rebuilt for performance, and added other mods, 4BBL Aluminum Intake, Holley 390 4-BBL, Dual Exhaust Headers, Aluminum Valve Cover, etc. I ended up pushing about 180-200HP out of a 258 that was originally rated for 110 (at the most). And it wasn't an extreme mod, it was my daily driver. Ran awesome, and I passed the motor on to a local in trade for this entire '77 CJ w/360 that he had (I gave him a couple other things too).

So, now that I have got my (his old) "project" close to being on the road, I'm curious myself how I'll like the 360. It's got some nut, and it is bone stock! Driving in 3rd gear, simply stepping on the gas hard spins the tires, LOL! <img border="0" title="" alt="[Eek!]" src="eek.gif" />

4wheeler4CJ, I want your Jeep! It sounds so freaking cool. That's how I'm doing my Jeep when I get the money. By the way, where does your dual exhaust exit? I was wondering if you could mod something up to have dual exhaust like a semi(with tractor caps and all). Or out the back. Or fenderwell exhaust. Where is the best place to exit? Hmmmmmm....

'87 YJ,4.2L 6cyl(rebuilding someday) On 33" Mickey Thompson Baja Claws, (unlifted, but big lift in store, when I get some $$$)upgraded clutch and brakes, broken loud stereo.(Can't imagine how that....COUGH!..WATER....happened. Haven't used a top doors or windshield in uh,.....hmm.... since midwinter? That sounds right.

On my old '77 with the Built 258, I had the dual exhaust built all the way out the back. It was a tight fit, but I had a custom shop do it for $400 total, and he does it nicely, taking 4-wheeling and interference into account. He "squashed" the pipes into a different shape where necessary to minimize tire rub, and put bolted connections to make removal of separate pieces simple when the tranny had to come out, etc.

On my 360 project, I just ordered Fenderwells today to replace my crappy In-Frames. I'm going to build my own custom 3" exhaust out of Dynomax Ultra-Flo Welded Mufflers (3" inlet & outlet) with full 3" pipes as well from the 3" Header Flange back. Just a side-pipe system exiting in front of the rear wheels with Stainless 4" Dynomax Tips.

Should sound nice!
