The site is www.rebuilt-jeep-engines.com Not computer savvy sorry no link. I know this is the age old debated question. the cost is 1248.00 with 150.00 core. Description I cut and paste follows. Sorry its kinda long.

Here it is:

What is the description of Jeep engine long blocks?
All long blocks come with cylinder head(s) attached and valve train installed. Valve covers, timing cover, intake manifold and oil pan are not included.

All long blocks have NEW valves, valve springs, valve keepers, push rods, rocker arms, fulcrums, lifters, camshaft, timing chain (belt), timing gears, valve guides (diamond honed), three angle seats, cam, rod and main bearings, pistons, piston rings, rod bushings (if applicable), gaskets and oil pump.

All cylinder blocks, cylinder heads, crankshafts and connecting rods are cleaned and shot penned and magnafluxed for cracks. All bolt holes are tapped.

Cylinder blocks are bored to each piston and diamond honed to 18RMS finish. All oil galleys are hand brushed with white cleaning brushes and cylinders are hand cleaned with cleaning solution and white towels.

Cylinder heads have each valve guide diamond honed, seats are three angle. After assembly, heads are vacuum checked for valve seating.

Crankshafts are ground and polished to 12RMS. Each oil galley is hand brushed with a white cleaning brush.

All connecting rods are honed.

It's interesting. THis site, and details look real good. HOwever ther was a recent thread there about reblt motors, and a place in Spokane came up. HEre is the link.

Although it looks a little differernt (?), it must be the same place. Frankly, these specs look terrific to me, I would check out the warranty, get some refrences etc. If you DO buy one, I would really check it out carefully for quality prior to installing.

Sorry, I'm not good enough enought to tell you if this is a good engine.

I just noticed that this website do NOT list AMC401 as a Jeep engine.
Wouldn't it be cool if we could swap a rebuilt 401 in place of our 360s.

FSJeeper 09-18-2002 02:41 AM

But for the 3 angle valve job and resizing the rods, most engine rebuilders pretty much stick to those specs in their advertising. May use different parts manufacturers but they are all similar. In short, this could be considered an average rebuild.

One thing I noticed I would steer clear from, they are not using new cams but regrinding the old cams. These are known to not be hardened back to spec and do not last. This is a shortcut way for them to shave $50 to $75 off their costs. I would only go with a name brand cam.

For that price, you could take your block down to a reputable machine shop and go the extra mile with blueprinting, line boring, precision balancing, better pistons, gapless rings, and a good cam and lifters. Most machine shops have engine builders or know of builders that will do it right. Plus you have direct contact with the responsible parties if something does go wrong.

I would be careful about the cam like FSJeeper said. It seems like a good price but how much for shipping? Is it included in the price? Shipping from Seattle to Albany could be expensive. Also take into account shipping the core back.

88GW 09-18-2002 03:36 AM

I agree with the cam situation as well. I have already spoke with them and they will put in the cam I spec'd out to them. As far as shipping goes I will have to get more info. as well as a core return charge too. Some of you mention building a motor for this price. I have priced it out here and it will approach 2000 dollars easily and there is no guarantee that I will be able to use my OE block or heads if they have cracks.

FSJeeper 09-18-2002 03:49 AM

When you turn your core in they check for cracks in the block and heads. If cracked, they will not accept the core. AMC engines have a very high nickle content and are not known for cracking.

I am beginning to realize that stuff is a lot cheaper in Texas than on the West or East coast.

Look at it this way, by the time you pay shipping both ways (longblock/core) and then run the risk of having your builder on the wrong coast if something goes wrong, I think you would be money ahead having it done locally.

The trick is to start posting on local car club boards and find one of the smaller owner operated machine shops and stay away from the big outfits.
You may have to go rural, but if you find the right shop, I think you can get it done for around the same price as that mass produced shop in Spokane.

I called this place again. There name is S & S machine shop out of Spokane Washington. Has anyone heard of this place? It was mentioned in another thread but I couldn't understand the post. It will cost me 1568.00 with shipping and I would be able to keep my old motor. Any Ideas??

TexasJ10 09-18-2002 10:52 AM

Do they balance all of the rotating componants as well?

khurst 09-18-2002 12:48 PM

Well, I guess I am the Guinne pig--I'll let you know as soon as I get my 401 from them. I did alot of research(3 yrs looking) and did notice what fsjeeper said about the cam. I had them install a comp cams 260, molly rings, and a dbl roller timming chain. I also had them balance the engine with a flex plate and harmonic balancer that they provide. As far as my research has indicated they have a 2% return rate. Not bad considering-however they will only pay half the shipping back to them in the event something does go wrong and there 7 yr/70K warrenty is pro-rated. I went with them cause I couldnt find anyone else who matched there warrenty and had a 401 not to mention the shipping price was really reasonable(250 to my door). If you want hold off and I will let you know how this one runs I would hate to see anyone else get burned. Later, Kirk
