So are you saying you run a 304 with a flexplate balanced for a 360 and don't have any issues?

im swaping out my i-6 for a v8 and was wondering what the hp difference is between the 304 and 360 and if that difference is worth it to get a 360.

Any year AMC V8 will bolt right in. The reason years can make a difference is that smog laws can differ from other years meaning some engines may have smog controls and some may not also other things like 4bbl or 2bbl carbs and what not.

http://jeeptech.com has some numbers on both engines.

Are all 360's the same

Will a new crate engine from mopar fit right in replacing a 258 in my 1984 cj7?

No, all 360's are not the same. Ford, Mopar, and AMC have all made 360 cu in V8's. They are totally different motors. Nothing will interchange between them.

If you want a ready to run crate engine with a warranty, look at Jasper.

If you want a core motor to rebuild or possibly a good running used engine, look at fullsize Jeeps. The AMC 360 was used up until 91 or 92 in fullsize Waggys. You can usually pick up a rebuildable core for little $$.

oil pressure issues!

Just completed my 360 swap in place of the blown 258. I got everything running on Friday, & aside from a tranny line leak, the only issue I have is with the oil pressure guage spiking all the way to the right when running. I hooked the original oil pressure wire from the 258 to a similar looking module right near the oil filter. My 360 was from a 79 Waggie & in now in a 76 CJ7. Is my wire just grounding out somewhere, or do the 2 diff. models report oil pressure at 2 diff. volts, thusly freaking out my CJ guage? The guage worked great with the 258 until the motor threw a rod, & the 360 while in the wagoneer always showed moderate to slightly low pressure. The guage also doesn't peg when the ignition is tripped, only when the motor is running. Any help is appreciated, thanks!

It sounds like you are using the factory CJ oil pressure gauge. I would recommend hooking up an aftermarket mechanical gauge and see what your oil pressure is. The factory gauges are usually way off.
