Why does it have a 401 .30 over. 10.2 piston in it if it’s a 390 What’s going on ?

I can hear his anger continuing to raise throughout the video. I'm sorry man, it happens to all of us.

I know who he bought that from

Do you know anyone with 67 Rebel body parts? Need a windshield to start with.

To be honest it was a crook that did that engine. Who in there right mind would put pistons in backward? Front means front.

The fact that the pushrods are used doesn't make them bad. The strenth of the pushrod i dont think should be a issue. What is more important about the pushrods is if they are the proper lenth. Most people buy new pushrods during a build is not becouse the old ones are worn out, but becouse with any changes to deck hight or milled heads or cam & lifter changes made or different rockers all will affect valve train geometry so new pushrods are required for proper lenth, not becouse of the integrity of the pushrod itself.

Classic performance piston flip!😅

When I see crap like this done to already niche AMC motors, a little piece of me dies

YIKES = $ 10,000.00 = YIKES = I'd SUE !!! ... COOP the "AMC JUNK COLLECTOR " = WiSeNhEiMeR from Richmond, INDIANA

I actually prescribe to SMOKEY YUNICK 1-3-5-7- swap with 2-4-6-8- Piston Swap on certain AMC V-8 engines because of the offset WRIST-PIN Offset & the FREE Compression Bump COOP ...

Those HEADS are very desirable = High Compression Dog-Legs if they are BIG Valves items COOP ...

1970 heads on a 1969 block requires a special DOWEL for 7/16" bolts to 1/2" head bolt holes COOP ...

HOWDY A-S-G, ... Interesting DOG-Leg Exhaust Ports = Later model HEADS on an allegedly 1968 / 1969 Engine that came with RECTANGULAR Exhaust Ports & I never subscribed to that UNDER Intake Manifold EXTRA Oil Line ... Thanks COOP the WiSeNhEiMeR from Richmond, INDIANA ... ...

And what did you pay for this thing? My last big block that I had built cost me approx. $32,000, BUT, it was built by a reputable builder, came WITH all receipts, came with all the parts manuals, literature, and contingency stickers, I received a build sheet with every spec for every clearance and setting of everything in the motor, AND the engine was dynoed (which i got to witness) and I received the dyno sheets for all 16 pulls, the oil filter was taken off the motor after the pulls and cut open right in front of me to inspect it, and then the motor was removed from the dyno, all open ports taped up, the entire thing crated, and forklifted into the back of my truck, and then a final receipt was given to me for all the work done, and presented to me (along with all the before mentioned paperwork) in a very nice logo'd company folder. The engine is on it's 3rd season of mid 9-second quarter mile passes in a 3750lb car with zero issues.... and there's more in it if I wanted to turn it up some more.. 🤷🏻 You DO get what you pay for

Blue paint overspray all over the valve springs... 😂

If ANYBODY has rebuilt more than a few engines, they KNOW better than to use the cork OR rubber China rail gaskets and theyvuse RTV instead. Those included in the gasket kit China rail gaskets WILL fail and end up pushing out in NO time. THROW those gaskets in the GARBAGE, and use Permatex Right Stuff instead.... you will NOT have a leak if you do that, but you WILL have a leak very shortly if you DO use the gaskets.

Looks like a lotus badge, but the sign in the trunk says it all. The tittles of the video look to be more of an eye catcher .😂 glade, it caught your eye

WoW, what a sexxy car. I love the Nascar boom tubes, I bet it sounds amazing. 🙏🙏

Very nice indeed

❤

Hey boomer, clean the lense

I'd go get my money back. Where I'm from, that's maybe $500 sitting there.

Flipping pistons is an old hot rod trick but the rod cheeks must be corect if you don't chthe rods on the pins you also have to change sides.my question when someone says a motor is rebuilt my question is usually ya but how much

Pretty paint is sometimes a caution flag. Maybe its part of a good job... maybe its just a paint job. In this case... motor needs a complete rebuild - surface the block, pick through the heads, whole nine yards. Probably needs guides, and recut the seats.

the pistons are on the wrong bank switch them ? but you need to dummy fit one to see if the rod in centered ! Check if those are 401 heads ? if they are 1972 or above it's a + ... I would be most concerned about the head bolts Yeah it got's dowel pins but NO . unless the cam is over 480 lift on the cam lobe I wouldn't hesitate reusing the push rods at all ? they are already tested ! Early roller rocker arms were not for street use , later ones are good to go . My friend Gerald had a new AMX and he thought nothing could take him ? He raced for 50 bucks a 66 327 SS Nova and lost 50 bucks . Gerald was thinking how with so much more CR ........ Good luck and get it magnet fluxed before any thing else

If you send it to me for free I'll give it a crack! 😂 🤪

Yeah car guy oath is no longer in affect. Heard of a local bought a used texas speed 6.2l for 12k, motor looked perfect , but had dropped a valve , broke a rod.

Lets pop out the pistons and check the bores, and magnaflux that crank before using anything.

I spy with my little eyes... Hot spots everywhere on that crank

It's not a gocart it's a lotus 7.

not a big deal

This is an example of when you uncover one lie you know the seller is full of shit.

I am confused. You claim to be an expert and have a video on how to ID an AMC V-8, yet you didn't see the obvious clue it wasn't a Gen 2 390. The dog leg vs rectangular exhaust ports, no disassembly required. The other obvious error is that you incorrectly said the priority oiling line is in the incorrect location and then point to the water jacket (also claim to have a video on this)🤦‍♂. The line is in the correct location in the passenger side lifter oil galley between cylinders 6 & 8. The purpose of this line is to take oil from the front of the engine off the line from the oil pump and inject into the passenger side lifter oil galley, which is where the mains get their oil supply. The reason is at high rpm the oil pressure loses from the front to the rear of the engine due to drops at each lifter. These are control leaks in the engine. It is also recommended to put a restrictor in the driver's side lifter oil galley to limit the oil to this side. Also, most engine builder don' t use the supplied seals for the china walls because of leaking, but rather use silicone. Since there is a deck height difference between Gen 2 and Gen 3 engines of .043" something had to be machined to make it fit. BTW, those valve covers are Chinese junk. You can google search them all day. And who pays $10k for aerosol overhauled engine?

Whoever "rebuilt" this AMC 390 sure is hell did a VERY s***ty job. I really don't blame him for being p***ed off. He should send it back to whom he bought it from.

There's a lot of stuff to check when building a motor. Casting numbers, piston quench, rocker arm geometry, replacement of common wear parts, ect... proper piston orientation now🤦‍♂️. I hate that this happened to you! Now, you're going to want to want to magnafux the block and heads, check the cam, the main caps, the rod caps... I don't envy your experience with this engine. Good warning, thanks for the information in this video.

You pay a bunch of money for a supposed hot motor it should come with reciepts

If you paid too much fine but there's enough good parts there if the block and crank are good I understand the rant but everyone knows you never trust someone who you don't knows work and wasting the aluminum covers is just a jerk move cuz you're mad you got took

Too soon to say about the pistons being clocked backwards. Im not an AMC guy, but judging from the valve reliefs on the pistons, it APPEARS that the pistons can be clocked 180° without valve to piston interference. There are SOME (race)engine builders who claim piston offset(& piston slap) can be ignored for purposes of more HP. I'm not claiming that that was this builder's intention, but it is a possibility. Like you said, it will be interesting to see if the rods are oriented properly on the crank pins. That will probably indicate a lot about the expertise of the builder. I feel for you, because what I've seen so far, does not look like it's worth anything near what you paid for it. Good luck. You'll probably have to check and verify EVERY last thing on this to satisfy yourself.

that's a real bad feeling if you uncrate something like this and then slowly get more and more worried then angry.

Your fist indication should have been that the whole thing was painted in one shot, except the covers. When I build an engine, I refinish every part before assembly, you can literally see every gasket isn't painted over, its a fresh and clean finish with everything indepently put on with care to the fit and finish of the engine.

I wonder if the rods are actually backwards or if somebody intentionally flipped the pistons which is an old school trick to load the rod up sooner.

That's proper AF!

What a beaut

Now thats a heavy car

That 73 road runner looks just like the Scrapy' car daisy drove in the 1sr season.

Watch R.I.P. don't let them be forgotten

I undestand the 'souls' thing rather well.

Look like money pits to me

Yessir works every time

We men really are just little boys with more money.....or something like that...🤔
