I like different so I'd go with the big AMC fish but then I have a turbo'd 401 dog-leg AMC in my tank.
  Sid.
Is there a build thread or video? I've only found a few videos of the 401. One of the videos had a Vortec supercharger.
I've never done a build diary on the tank or the streamliner for that matter, I hardly ever even take a picture of my junk! I built the tank eleven years ago & it's been parked since I started building the liner seven years ago.
I went to the AMC forum way back but experienced a bunch of wankers there that said I couldn't do what I had already done so I moved on from those Einstein's!
I used a turbo off a power stroke Ford on my 401, I just rebuilt it with an up graded compressor wheel & sent it down to Salt Lake to be balanced. The engine is stock other than a set of Hypereutectic pistons, a 260 Comp, ported heads matched to an Edelbrock Performer & the big 1979 Wagoneer exhaust manifolds. The turbo is on top of the trans & blows through an 850 DP Holley & there's a $60 Chinese HEI parked in the front of the thing. The trans is a short Dodge motorhome 727 that I rebuilt inside an AMC case due to the lack of room in the tank for a full length one.
The 401 is no different to any other engine in it's construction really but there are a couple of quirks. The oil pump is in the front cover & the gears kinda wear it out giving low oil pressure at idle but there's a cheap stainless plate fix for that so you don't need to buy a new cover. Some people do a transfer oil line in the valley to the rear but I think that is more of a fix for the low idle oil pressure thing that starves the last bearings on the supply line. I didn't do mine & haven't seen a problem.
My old pile made just over 650 at the wheels on a dyno here in Spudland at 4k feet & you don't want to know about the kitchen pot/carb hat for the blow through.
If you go looking for one, the 75-78 Wagoneer is the best place to look if you want to run iron heads but the 401 was an option not standard & 401 is actually cast in the side of the block by the freeze plugs so you can ID it. There is also a tag on the left valve cover to ID a 401 & that has a Z stamped on it but the hypo 343 also had a Z tag so check the block to be sure plus the 7th digit of the vin code will be Z.  All the 401's have forged crank & rods, only the late ones had the dog leg heads & 1/2" head bolts.

Sid,

The machine shop I have access to is T&T Race Engines in Gurnee, IL.    They are primarily a drag-centric shop, but they do take in sprint car and road race projects as well.     Of course they speak fluent SBC, BBC, LS, BB Ford, SB Ford.    BUT, they do a significant number of "orphan" projects such as Oldsmobile, Pontiac, and AMC . . . . . .       Currently, there is an AMC 401+ size project wending its' way though their shop.   I haven't been paying attention to the exact size, + something on bore with a slight stroke increase, but I will find out.     The project has INDY alloy heads and not sure on the other specs.

They are planning to dyno it on their Superflow 902 engine dyno when completed,  I'll get you the dyno numbers along with the missing specs.

 :cheers:

Yep! There's junk & then there's junk & I was definitely referring to junk. Man I'm glad we got that straight. :-D
Mean time we have 6ft of snow & I worked on the liner (junk) until 3.30 am.... living the dream. :|

Sid i think my street 401 for my 70 Javelin (bit of a never ending project while i have salt bikes) has more build into it than your race motor
Have a Vortech SC for it , h beam , forged pistons, looking seriously at Aluminium heads over the cast of which i have several options , mainly as the cost of rebuilding the cast is not much cheaper than buying the aluminium .
went with the new front cover and x over oiling system
crane solid cam
EFI

Amc is going to cost a fair bit more than a Chev to build, parts are of limited options, and people who know from experiance the best way to build them are rarer than blue hats

Good luck with the build ,
Oh there are a few articles in old hot rod mags on building a 401

Yeah that wouldn't be hard Maj. I'm not too interested in building naturally aspirated engines for myself, ya just fill them up with $$ trying to improve the volumetric efficiency & still lag behind a boosted engine. My turbo 401 owes me chump change, the liner is twin turbo'd, my truck is turbo diesel, my daily driver is blown & I have two girlfriends....sorry, I got side tracked.
Being way over square with good organs from the factory the 401 is an ideal candidate for boosting.

I wonder what happened to polyhead. The last guy who was going to build a abnormal Bonneville car?

 :cheers: couldnt agree more Sid
The only things i own that are not blown is a Triumph dual sports bike ( and that was a close call) and another Javelin a 68 that will remain original
Very difficult to go back to NA , think i got the power surge bug as a kid on 2 strokes  :-D

Hope all this has fanned the fire Tackman

Thanks for all the input on this thread. I had something very good happen today at work. The inspector on this project told me about a car that a friend of his son left at his house a year ago. He was told to give it away if someone wanted it. It is a 1986.5 Toyota Supra with the 24v Turbo that hasn't run in 2 years but is in overall good condition. I am picking it up on Friday and will post pictures then. I wish that Marlin would've worked out but doing this on a budget I couldn't pass up a FREE car that has this much potential.

Sid....not relevant to the hobby, but...that oil pump story reminds me of the AMC police car program.  Long ago I had a friend who was employed at AMC, working on that project.  Interesting story, and by strange coincidence.... came back and bit some time in my career with a "popular foreign brand".

When they put together the AMC police cars, the performance and handling were quite good and the slightly more compact exterior (narrower) was found to be an advantage for certain situations.  When the field testing started, they eventually ran into oil pressure and oil temperature problems.  And so it was....some years after hearing the stories at a late dinner, I found myself involved with a similar police car project that ran into a similar problem.

We had put together a police package demo using our newly introduced V6 powered 4-door sedan.  Handling and performance was pretty decent and fuel and brake burn costs were a nice improvement over the (then) available products for patrol cars.  Brake burn, for city police cars, often costs almost as much as the gasoline bill (per month).

Within a few months we were getting engine knock complaints (always the number 2 piston scuffed).  We had zero problems in civilian use, and so I sent an engineer down to Arizona to "live with the cars" and figure out what was going on.

It was the same problem as the Ramblers (we learned).  The test cars were all given to "near retirement" older officers for the initial "long term use" period.  In actuality, they tended to spend a lot of time idling in the shade with occasional full throttle jumps to chase down a traffic violation.  The extreme long idling pushed oil temps too high and the last piston in the coolant flow pattern was the first to scuff when the officer woke up and did some police work.

My friend later said, "Yup....just about exactly what happened to us at Rambler."

My daddy always said, "There ain't nothing new, under the sun." :|

Hope you enjoyed the little story.  JimL

Customers can find ways to "abuse" products that engineering and marketing never imagined!  :-o :cry: :x
With apologies to our blue-bloods, panic stops at the doughnut shop don't help the brakes either!  :-D
Mail delivery and paper routes drastically alter the fuel/brake cost ratios, too! :-(
