I'm putting a new engine in the CJ and I wonder what I should do. I got a 360 but I'm wondering if its too much to put in the CJ???? Should I go with a mildly warmed 304, the prices are pretty close. The 258 is the same price. I don't have to worry about emmissions, so would the MPG be a huge difference??
Any of the three would work but it would depend on wether or not your trans can hold up to the V8. If you already have the 258 you could keep your bell housing for any of the transmission and if you are worried about the mpg you can put a motorcraft 2100 2 barrel on the 304 and you should have plenty of tourque.
I have the 360 in mine and I like it. Its mostly stock and it has plenty of everything I need except ability to run on anlges. For that reason, if I had to do it over again, I would seriously consider a 4.0 from a wrangler. Other than the fuel injection I'm very happy with my 360.
I have had all three engines in my CJ and currently have a 360 out of a 78 J10. I can say that the 360 is definatly the powerhouse and work horse of the three engines and the 360 is cheaper to build than a 304.
If you are putting a new engine and satying with amc please consider the 360. You wont be sorry!
I got mine in the Thrifty Nickel paper. I still have the pickup, its a 75 J-10 that I'm probably going to part out with the other pieces of the 258. Brand new engines are really cheap actually. I can get a brand new 360 with 2 year warranty for 1095 and 1193 without tax. I might just do that.
