Happy New Year!

Certainly you don't meant the AMC 304 with it's whopping 125 HP?

what, all 220 ft/lbs?
ONE year for the 304 was decent. ONE. the 1971 version made 210hp and 300ft/lbs.

220 is from the 80s the 70s makes 245 at a mere 2500 rpm.also how much does a cj7 or a cj5 weigh?
Besides it uses a carb and has the same bore,stroke,and compression as the 71 model just replace the exhaust and switch to a more efficient 4 barrel and wa la

check the numbers for yourself:
Jeep Engine: AMC 304 V8
the 3.8 in the jk makes about 225lb/ft at 2500 rpm, not exactly a huge difference. it also gets a hell of a lot better gas mileage than any 304 could ever dream.


it's not terribly scientific, but here's the 304 in action.


obviously the cj was lighter than more modern jeeps because of their bare bones nature. an auto 2 door jk for example can 0-60 in 9.5 seconds. there's not much data out there for the 1970 304, but the later 304 cj's would 0-60 in about 11.5 seconds and slower, depending on the year. was the 1970 at least 2 seconds faster to 60? i don't know.

it should also be mentioned that power ratings back then were not sae corrected like they are today. the power rating on an old engine was derived from the engine running on a stand with no accessories or drag whatsoever, in a controlled environment. modern sae ratings give you the power the engine makes as it sits in your vehicle. here's some reading on it if you're interested: http://www.land-and-sea.com/dyno-tec...horsepower.htm

Again replace the restrictive nature of the engine and exhaust components and watch the 304 scream.It is not the 304s fault it came about in a time when the U.S. was cracking down on emissions all engines suffered around this time.

well sure, if we make the 4.0 and 3.8 illegal for highway use by tampering with the emissions systems, we can get better power numbers as well. talk about mod for mod and any comparative purpose is lost, we can only compare stock to stock.
i added a bit on the end of my last post, check it out.

Thank goodness the only thing emissions wise they check for down here is wether your diesel engine is running on farm fuel

ugh, tell me about it. maryland does emissions every 2 years, but you only have to get inspected once when you tag a vehicle. no inspection or emissions with historic plates, though (anything over 20 years old). that's why i'm into old cars.
the worst part is i have PROVEN that you can make a carbureted, non emissions engine run clean enough to pass the sniffer tests. my dad's mostly original, unrestored survivor 59 vette has the original the 283 and carter carb and can knock down damn near 30mpg and burn clean when tuned properly. you can easily do it on an injected motor without the need for catalytic converters, but they keep ramming this emissions crap down our throats. i've seen gm ls engines make 500+ horsepower and burn clean enough to not need cats, on pump gas (not ethanol).

you know why farm diesel is illegal? because you don't pay tax on it. seriously. the "high sulfur" nonsense is ridiculous. you know that smell a catalytic converter makes? that's from sulfur. if you can smell it, it's being released into the atmosphere.

if you can't tell, this is a touchy issue for me, lol.

I got to drive a 304 Commando for a while (they were putting a new engine in my new Cherokee) back in the mid 70s. That thing would fly! I shoulda bought that one instead of waiting for the POS Cherokee to be fixed.

Wow, didn't mean to stir things up with the 304 comment. With that said, my last two Jeeps were '76 CJ5 with 258 I6 and '75 CJ5 with 304 V8. Regardless of what the numbers say the difference in performance was significant both on and off the road. I sold my 76 to buy my brothers 75 for that reason. Well plus I wanted the Dana 44 too.

Ahh, I miss the CJ's but have come to like the modern Wranglers quite a bit.

Back on topic, hope everyone is enjoying the New Year!

Cool.....The guy (Danny) called me yesterday (again). I think I could have bought it for $30K.....about 2K less than I'm paying here. Shipping though, would eat up a lot of the savings, plus I have a friend at this dealership (although he ain't TOO good of a friend to not give me the $break). If you stop in at Performance Jeep, tell Danny that "Don" said hello, and that I hate it didn't work out that I could buy from him.
