is there parts support for the amc 304-360 engine?

Hi, i have a yj, but have been wanting a v8 jeep, i have been looking at cj5`s and 7`s with v-8 . I am wondering if i should find something with a chevy or amc .

My question is can i buy new parts for a amc 304 or i would have to search used for parts ?

The 360 and 304 are rather popular engines, you should be able to find new parts at jegs and places like that

I have a 77 cj7 with the 304 with the 3 speed. From the factory it had 1550 horse and 219 foot pounds of torque. I'm not sure how that compares to your i6. But it also depends how its geared and if its a manual or automatic and the gearing of the axles. The v8 is gonna create a definite different sound than the i6. I prefer the sound of a v8 to a 6. But its just a personal preference.

I liked all the 304's that I have had but if you want truely powerful then that's probably easier and cheaper with a small block chevy

Yeah the Chevy engines are always going to have more parts for cheaper, parts are pretty much a dime a dozen for those

I am currently building a '84 CJ-7. I put an AMC 360, TH 727, D300 and Scout II axles in it. I recently made two major purchases. The first was the Howell Injection for the AMC 360. That set me back $1300 plus the time to install it. The second was an '89 Suburban for the new BFG 35" MT KM2's. I paid $970 for the whole thing, it runs and drives well. The 'burb is a TBI 350 with complete wiring harness running and driving. Pulling it will cost labor and installation but is a more cost effective alternative to the AMC. AMC parts are available but are more expensive than a small block Chevy.
Best of luck to you on your decision for it's AMC all the way!

I enjoy my 72's 304, but once it dies I am definitely swapping for a Chevy. As for sound my 304 sounds great with the cheery bombs some previous owner slapped on.

I don't think there is really any benefit swapping a 304 in place of either the 258 or 4L other than you do get the V8 exhaust. A 360 would definately be an improvement and while there are a lot of people that like AMC 360's but i'm not one of them. Not only are there magnitudes of more parts available for the Chevy small block-and they are cheaper- but the sbc for some reason is just a more efficient platform. My best mileage out of a 360 was about 14 mpg but usually it was below 12 mpg. The 383 sbc in the Willys gets 18 mpg on a regular basis.

Good advice here. i agree about the 304 and the 6cylinder.

If you are looking at a Jeep with a factory v8 to get more power , forget it . They didn't have that much power from the factory and by now , have alot less.Drop a short block in there and be happy !

Agreed, when I had my Scrambler I transplanted a built 304 into it, replacing the tired I-6. Wow, what an improvement. But my V-8 was completely rebuilt with a low-end cam and tuned perfectly. I could burn rubber (with my 35's) in 1st, 2nd, 3rd, and 4th. Yep.... not long after the swap I had to rebuild the T-5 tranny too.
And don't even talk about gas mileage. I was getting 13 mpg on a good day.
...One of the reasons I had to part with her ... as a daily driver that's hard to justify.

How do you know it's putting out 330 h/p ? What did you do to it to get it that way ?

The 304 is a good torque motor not brute HP for speed. In my usage scenarios, I have always found the low rev torque of the 304/360 motors is good for off road and can be an advantage over the hi power of the the SBC conversions. Once you start spinning tires, the battle is lost so you want a motor that you can lug down and still pull, and the 304 can do that nicely. Not saying the SBC isnt a great conversion, but you will need to adjust your driving style (or gearing) to compensate (unless your making a Mall Crawler that will only see the street )

I totally agree!
