Reman engines

Hello, I am wondering if anyone could help me out. I need to replace the motor in my 1979 cj7. Its a 258 i6. Can anyone tell me who has the best reman motors out there. You see lots of negitive reviews on a lot of reman motors and i just want to get my moneys worth and not get ripped off.

are you personally changing the engine? if you have the talent to change one then you probably have the talent to rebuild yours. if not another good option is find a local machine shop to rebuild yours. it will be more expensive but normally local shops will use better parts and let you chose more of what brand you want to use. most big engine overhaul companies use cheaper offshore parts. my thing is i like to use american name brand parts from companies that have made parts for years in the USA. some of them have moved some things offshore but hopefully they have a decent quality control department. i like clevite bearings, kieth black silvolite pistons, but the most important thing to me is the lifters must be made in the USA. a big C cam company wont say where they were made when i asked. so to me that means offshore. Crower cams told me they used Johnson lifters when i asked. they are made in the USA.

I've heard Jasper has gone downhill but I don't know that from personal experience (just my mechanic complaining).

I've had good experiences with S&J up in WA state. I did get one bad motor from them, but they replaced it under warranty. The motor developed a crack in the block during break in...I'm told it probably had a hairline crack in it that was not able to be seen during inspection, and then when they bolted the head on it made it worse internally, and then it developed during hot/cold cycles. Not sure if that's BS or not, but they did replace it. They paid me for my time and shipped me a new motor. Not that home installers get paid much by their warranty lol. But if you pony up a few extra hundred dollars they'll give you a gold warranty or some such.

I am 100% onboard with the Local Machine Shop opinion. Ask around at the local repair shops for a referral if you don't know anyone you can trust. If I needed an engine for mine I would probably look around for a rotted out jeep that I could run and drive and buy that. If you have someone rebuild yours it will probably run you 3K + if they do it right. Might be able to buy a junk jeep for a grand.
