lost a motor AGAIN!

[Sambo]

lost the rings me thinks! smoking real good off left bank...possible culprit #1 cyl.
i also have an oil leak near #1 on the exhaust mani now,that i just noticed after getting home...

i friend gave me a 350 to build,and a kid i work with said he can get me a 700r4 cheap enough

Sam, I'd go the 350/700R4 route myself. Your D300 will bolt willingly enough to it (you'll need another adapter obviously) but I think you'll be happier in the long run.

don't mean to pick a fight, but are you guys serious? not many here have hit 200k on their AMC's without digging into them. 150k is nothing IMO for a motor to blow through.

I don't think thats necessarily an engine fault so much as FSJs usually don't make it to 200k as a whole vehicle.

I don't know if you rebuilt the last one or not but sometimes it's the mechanic. Not trying to start anything but sometimes even the best of us mess up.

I flog the crap outta my 360 and it's still holding strong. I don't know, maybe you have bad luck.

Probably broke the ring lands off the top of the piston. (which is detonation) Or collapsed/broke a skirt. (which is overheating or detonation)

Not the name on the valve cover.

I daily drive 2 different 180,000 mile late grand waggies with the 360.

I have had good and bad luck with just about every domestic V8.

If I ever decide that I REALLY need big cubic inches, I will PROBABLY do a 505 inch Ford 460. Not because I like them. Because it bolts straight to my NP435. There are success stories and horror stories for every engine on the road.

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.

yep thats what i think! these motors all had recent builds before i got em,so not knowing milage or how they were built i had no clue.except this last one seemed pretty strong till now

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
