Dont get me wrong, sbc 350's are a darn good engine, if someone tries to tell me that 350s are junk i'll say they are foolish, but ive found that the 360 amc seems to run stronger than similar built 350s. I feel that the worst thing you can do to an amc is put a chevy motor in it. The fsj's are unique and amc power makes them even more cooler. A chevy powered amc fsj is just another chevy powered rig.

Youve probably got something stupid going on inside there. I dont think you should give up on the AMC. They are good engines, it just depends on how they are built to get durability. Ive seen lots of 350s fail also.

I dont see how anyone wants to get high mileage out of their old fsj's these days anyway. Thats why my DD is a chevy cobalt.

I'm just sayin, he's got the engine, and if he can get the 700R4 then all the better. Easy way to add an extra gear, better low gear and cheaper engine parts.

about any engine properly built fixing factory design flaws and limitations can be powerful and reliable some take more to build then others. i would compare the cost of building both engines then youll have to include the cost of all the conversion parts needed if you go with the chevy. just balance,blueprint it, and use quality parts and you can get a very long life from whichever you choose

How so? All of us have a Jeep full of GM parts, what's one or two more?

I never said AMC or GM is better one way or the other, engine wise. I simply said use what you have, and maybe get some more/better gearing in the bargain.

Sam's jeep isn't stock (from your avatar, your's isn't either) so I don't see how that can play into it.

Ultimately, it's Sam's choice.

Although I do see lindels point. My drivetrain is ford with chevy calipers and amc engine. Would I drop a cheby or ford engine in it? No. I feel like I would have betrayed my jeep, the engine is the life of it. I don't care how cheap/better a chevy or ford would be, but that's just me and I hate that he has had two amc's lay down on him, it wouldn't make me second guess the engine but second guess myself if I built it or whoever else built it

I have seen plenty of 360's go past 200k miles. And I think if anybody has shown how a 360 can hold up, its andrew. I don't see his sees anything less than 5k rpm when hes out on the trail.

If you got all the stuff for free sam, I would say its worth it to switch. Otherwise, fixing a single bad cylinder is pretty cheap.

And as asked earlier, did you just put this engine in in used form, was it a rebuilt engine, or whats the story behind it?

sambo, if you go with another used engine (even if they claim it's been rebuilt), you'd be dollars ahead to buy a gasket kit and some plastigauge and tear down the motor. Double check the bearings, wear patterns on the motor, torque on the bolts, check the pistons / rings / etc. as MANY folks, even rebuilders tend to either install them wrong or nick them when they are dropping them into the cans. Plastigauge to check the bearing sizes, make sure the bearings are the right size. Check the timing chain depth, etc. Yeah, it's bunch of work, but I'd rather spend a saturday tearing everything down and measuring, then have it all reassembled that night or sunday morning to be sure. Worst case, you see that you didn't get what you paid for and you then can buy the parts you need to fix the problems. But then again, I'm nuts and think that stuff is fun

it's called a joke

I could care less what he does. you're right, it's his rig. the only Jeep/AMC parts I have on my truck are the body, frame and engine. Everything else is chevy.
