Hemmings Motor News Blog

Hemmings Motor News has been around since 1954. We're proud of our heritage, but we're also more than the Hemmings full of classifieds that your father subscribed to. Aside from new editorial content every month in Hemmings, we have three monthly magazines: Hemmings Muscle Machines, Hemmings Classic Car and Hemmings Sports and Exotic Car.

While our editors traverse the country to find the best content for those magazines, we find other oddities related to the old-car hobby that we really had no place for - until now. With this blog, we're giving you a behind-the-scenes look at what we see and what we do during the course of putting out some of the finest automotive magazines you'll ever read.

Impossible? 401-Powered Concord AMX

Posted March 26, 2009 12:01 AM by dstrohl

As any student of AMC history knows, the one-year-only Concord AMX (nestled in between the 1977 Hornet AMX and the 1979-1980 Spirit AMX), had essentially two engine options: the 258-cu.in. straight-six and the 304-cu.in. V-8. So when forum member spf150 bought his Concord AMX (for $75!), he saw the V-8 and assumed he had the 304. But a ruptured oil pan led him to notice the 401 cast into the engine block.

This would not only be an impossibility because of the Concord AMX's engine options, well established in AMC literature, but also because AMC stopped dropping 401s into passenger cars after 1974 (though cop-spec Matadors got the engine another year), and because AMC never put a 401 into a small-body (i.e. Hornet, Concord, Gremlin, Spirit) car.

Holley Gosh! That's what I call an strong Puppy definetely. Great car. I'd had the opportunity to saw those animals in action years ago and you can tell how much juice those Puppies delivered on demand. Not many cars came out with so much engine power juice, incredibles. Congratulations on such enterprise and enjoy it the best. Lot of horsepower was the move of those times absolutely and great memories as well. I'd remember that came from sounding the tires as routinely when change to second gear even on automatic transmissions, awesones. Hi-Performance big time no joke.

Pretty Cars,

MC

You never know what might have happened in building autocars but here is one idea I have about what MIGHT HAVE happened. Somebody high enough up in AMC management might have had a strong interest in drag racing and may have been influential enough at AMC to get a thing or two done his way. Therefore, he decided to take a leftover 401 engine and have it installed in a Concord, therefore following the same thing started at Pontiac when they installed a 389 in a Le Mans and made the GTO; the only difference being that Pontiac built many 389's; AMC apparently built only one 401 Concord. I think since the VIN for the car shows it was built with 401 that this becomes a plausible theory. To my knowledge, there is little chance that Canadian AMC's had the 401 in 1977. As for the French wording, Renault had bought into AMC and the MSRP pages may have reflected this ownership. Am I right? Maybe not but it's worth a thought.

I remember a buddy of mine in high school had some how managed to fit a big V8 into his AMC Hornet. He went through an awful lot of tires showing off the power of that thing. He also managed to keep the outside looking like an original Hornet so when he pulled up along side some muscle car at a stop light they had no idea what they were playing with when the light turned green. it was Fun to see their faces when he blew them away.

Ah the good old days when gas and tires were cheap enough to do these things.

Oh and this same friend in later years ended up popping out his rear window of his car by having the stereo bass turned up so loud that it literary popped the window out of its frame. He always had more money than brains.

Awesone car. Deeeaaammnn that Puppy have a lot of HP absolutetly. I do agree that very probably that has been the case. Someone like the dragging around and came out with such concept,absolutetly, waaaooouuuuhhmmmnnn.....

As back then that was the fever definetetly. Those Javelins was very cute cars, I don't get it why they don't keep up doing it? You know stick with these styles since that was really the 'American' thing, I don't Know!

But anyhow unfortunetly good things dissapeared with time as well for one reason or the other. Who know's? Now these are show cars collectible classics and super attractive too. What a shame that they let it go that way, now is history I Guess who may afford to have one of these Puppy's anymore, not many I'll Bet!

But hey at least I'm happy with had the chance to saw them running back and forward, what a days! Remember those Dodge's RoadRunners and the GrandPrix's and the Mustang's 67-69 and a whole bunch of others as well, waaoouuuhmmmnn, unparallel no argue about it those was the real deal definetetly. But then came the FrontWheel a lot of SUV's and that was it, kaaapooossshh, no many more of the good stuff for everyone anymore, finitoooouhh, You got it be kidding,dont ya'? finisshhhhh! Deeeeaaaammnnn.............

What the H.......,

MC
