Machine going back to stock

Make sure the machine shop rebuilds amc motors
It's not a chevy.   

Many others seem to have been bitten with the low oil pressure issue after using any
Run of the mill machine shop

I suggest you contact jcisworthy on this forum
He's good with amc motors

Ccowx, he had another thread on linkage for a console M12. I gave him Info and yet to see Info he has found everything. Hopefully he has kept track of both posts.

I would not even think for a second about selling the valve covers or intake with the 4011!!! The intake is worth about as much as a complete 401 block alone. Remember the rocking horse manure? Depending on the condition of the chrome on the valve covers, they can be in the hundreds too. And hopefully the valve covers still have the little aluminum tag with the date code on it. That is also probably worth north of a hundred bucks too, and difficult to replace. All of these items are probably not worth much to the guy buying the 401 anyway, other than for resale. He may use his own valve covers, intake etc anyway. I would also keep the brackets and PS pump, if any, since those may be model year specific. If you are really concerned you could replace the valve covers and other bits with generic AMC pieces for much less than the items you have are worth.

Not to belabor a point, but here is a basic list of what to keep on your engine:

-Intake manifold, one year only and specific to the Machine engine
-Exhaust manifolds, same as intake.
-air cleaner, oil filler and valve covers, all chrome and quite difficult to replace
-Carburetor, also specific to the Machine
-Distributor
-Timing cover
-PS apparatus, changed in 1972
-Fan and shroud, if so equipped, including the aluminum spacer behind the fan.
-Valve cover tag
-Alternator and VR
-Cylinder heads, one year only

Bear in mind that the intake is probably worth at least $500, the exhaust manifolds the same, valve covers $200+, aircleaner housing and cover $300-500+, Carb $300+ for a core, timing cover $200+, VR and alternator $200+ as a working pair, etc. All this assumes you can even find the Machine specific bits at all, which I would not depend on.

Many of these items are one or two year only and/or specific to the Machine. Few to none are reproduced. Some guy is going buy your 401 for a hot rod and replace most of this stuff with the aftermarket of his choice and either sell it for enough to build his own engine, or toss it in the bin!

Nice car!

Someone has borrowed my TSM, so I am working off memory. I thought the Machine carb was unique, but even if not, any original AM Autolite 4300's are getting skinny on the ground and there is also the date code issue.

Thanks!
