Chemical dipping a Chrysler 340 Engine block 

You made lifting 161 lbs (73 kg) look easy, holy duck that's an entire adult.

A rebuilders dream to start really fresh

This brought memories of rebuilding an AMC 343 V8 back in 1988. I had it de-rusted and chemically stripped. It provided great peace of mind, knowing everything was cleared out and squeaky clean. The painting and reassembly were a breeze.

I know it might be a pain in the backside but maybe the next time you do a block you could do the weight difference after the alkaline bath and then after the finished job to see if the majority of the weight loss is grease, paint and the primary removal of the surface rust compared to the actual amount of metal removed from the acid process. I like this entire process because if you’re doing any sort of performance build with a 50 +/- year old block and you do a sonic check. It’s nice to have a legit thickness reading and not a reading that’s inaccurate due to rust surrounding the cylinders in the water jacket.

Your videos are excellent. So satisfying.

I Am a Paint guy to be honest, so I get this process and what you do. I have worked at GM for thirty plus years, weld and paint,stamping and assembly. Love your channel, cheers from Canada.

Wow!! That Block looks Factory Fresh.!

Impressed that you were able to hulk that block onto the scale before cleaning it

Nice! Every engine builders dream, of working with a clean slate. First step to a 💯 point car. 💯🗽🇺🇸

That was quite interesting. The person building the engine will appreciate the clean starting point.

I didn’t expect this one. Truly fascinating. 👍

I can't believe they left the core plugs and cam bearings in before dipping this block.

Great job! Love before and after!

Interesting to see the pathways of air/oil when you shoot the pressure washer through the various holes.

Seems much better than the typical "hot tank" process!

Man that 340 looked beautiful. Thank you for your work and videos.

any special prizes if you get all 8 balls in the cylinders? paid vacation? 😁

I restore old tractors. I have a 48 Ford in the shop now. I doubt that anybody who owned the tractor ever made 50/50 antifreeze with distilled water so the blocks are unbelievably crusty when the freeze plugs are popped out. The standard technique is power washing through the freeze plug holes but I’m beginning to think that maybe caustic then acid dipping is the way to go.

I once (in the 1980’s) rebuilt a 340 for an “In Violet” (purple) 1971 Plymouth ‘Cuda 340 that my wife drove for years. A great engine.

Looks like they didn’t get the memo of removing ALL freeze plugs and left two in.

GREAT VID. Love 340 motors.

Beautiful job man. Thanks a lot.

It looks amazing, great job

I'm a simple man and easily amused. The side bloorp at 2:49 cracked me up. I stand nothing to gain by lying, but my guess was it would be a 2.5 lb loss, so very close. What a cool video. Thing looks super clean now. I like how the balls fit perfectly in the cylinders. And hey, if you don't want a bad back when you get my age (protip: you don't), lift heavy stuff more with your legs and less with your back. I'm not being negative, you're a strong guy. But be nice to your back. You'll need it for life.

Holy cats! This is one strong guy. Looked like zero effort picking up that block.

You are strong dude !

I a 440 built. Before sending it in to be boiled and chemically cleaned I had to thoroughly strip it down. All freeze plugs out and mains removed. It was just the block and the other parts rods, caps, head's etc were boiled separately. The heads were also stripped all the way down. After it they all still needed a separate cleaning. You make sure the oil passages are clear and any remaining gunk or dirt is out of the block and off it. That is like standard procedure for the more professional and race engine builders. The guy that did the boiling/chemical dipping and machine work and short block assembling was a master race engine builder. Literally had decades building big block and small block Mopar Nascar, drag race and off shore powerboat race engines. If you really get into building you also do a ton of deburring and lightening of the block, crank and heads. Also port and polishing and balancing.

Just beautiful.

U did a GREAT job with the camera and the power washing.!!! The weight results R interesting.....FO SHO !!!! Keep up the fun videos. THIS IS GREAT !!!

You have a really cool job or so it seems from your videos. Thanks for sharing the process with us.

Well done- you have a great work ethic and an addictive channel!

That’s odd the customer left some of the freeze plugs in

Looks awesome 😎

Very nice. 👍🏻

That looks great 👍

It's truly amazing how well your first solution removes stuff you would think the acid would remove everything lol.... thanks

In my recent 340 build, the block weighed 159 lbs so I’m sure all that weight you took out was just the grime inside it. Very cool process for sure!

Enjoyed! Thank you

Lifting 73 kg of dead weight 😮. What are you having for breakfast? Cornflakes with Red Bull? 😅💯👍

wow you lifted that like it was nothing. damn no wonder you look so good

Fantastico! I cannot compete with that.

Why would't the owner remove ALL the core plugs and cam bearings? He better hope there is no acid stuck between a cam bearing and the block! Looks awesome, great job!

Great video

Very interesting. Thanks

Fairly cool process as gets the inside also fairly well. I was looking into building a new block for a car of mine reconditioning a spare used engine. Still tied between vapor blasting, chemical dip, sand blasting outside and manually cleaning inside. I think all of the methods would need work on liners and stuff.

For those with classic cars that are considering this process would you be able to explain some other details of this process, Topics like - *what are the effects of this process upon body seams, will they rust later *how sure are you there are no residual chemicals left in body seams, * does the acid totally dissolve large flaky rust that may come off while in the tank (such as inside rocker panels) *is there a greater chance of rust developing inside internal cavities after this process, *once the owner picks up the body how long does he have before the metal starts to rust over, *you wash the body down with the pressure washer but what about internal cavities, how do you know they are clear of gunk. *what about the underside of the roof, it would have a large air bubble preventing it being cleaned *once the car is taken home does the body need to be washed or cleaned further before applying primer *is any healthy metal removed during this process *are there any downsides to this process Otherwise great videos. Well done.

It looks beautiful and ready for a 523hp build

excellent !

Woo Hoo.158...right on the money..!!

Bout time you got a hands free rig to video

I didn't know people did this to engine blocks. I know shops that hot tank them and degrease them but not acid dipped. Id be concerned the threaded holes would be slightly oversized but maybe the difference is microscopic idk

I liked that little doll in the beginning after he started going in and looking down like wait what the heck is going on before he disappeared into the bath.

Wow Funny Pasty color going on Looks like chalk 😊

Why not remove all the casting plugs

I like watching your show. I bet you get a lot of business from this show. I ALWAYS hit the like button!!!

Amazing - love it, never imagined it would be that much 😂 Lift with yer knees tho! - Haha. Love what you do ❤

this is cool

Did not know I needed to watch stuff get dipped in acid. Where were you 8 months ago when I had a 440 to clean 😂

engine blocks will vary it all depends if it was ran with coolant all it's life or water because straight water will make it rust in the cooling ports compared to a engine that ran coolant all it's life. Many people think they don't need coolant when they life in warm weather climate but the coolant has anti rust additives along with anti freeze and additives to not allow it to get hot as quick as just water and the coolant was changed and flushed in its lifetime. I have seen old engines that have ran on straight water and it did not matter how many times you flush it the water would look rusty and there was loads of rust that came out of it.

That was interesting. I was guessing it might have only lost 1 pound, so a bit surprised it was 2-3 pounds. Like others, I can't believe the owner didn't remove the cam bearings and various plugs. It sure looks nice rust-free.

My old car and old engine 72 Challenger 340 Red with pistol grip 4spd in 1977! Blew the engine up 1 yr later and sold it

Great video. Cue The Doors LA woman ;)

Awasom

Молодчина!

You killed the joker.. dang

Other than getting stuck in the cylinders, what's the purpose of the balls in the bath? I'm surprised there wasn't more gunk lost off the weight, but re-watching the block was fairly clean to begin with. Thanx for another cool vid!

Looks new, might need new cam bearings😁

6:17 you missed to remove a cap...at least...the weight difference doesn't accounts for grime and metal loss but for grime and oxid of metal (that weights more than metal alone because of the oxygen). Our rocky planet weights a lot because of the oxygen in the minerals...

Coming at this from a different angle, I'd be interested in the requirements for maintaining the tanks, such as sediment removal timetable, refurbishing the solutions and what you do with all of the paint and crap after power washing. Great process and very unfortunate that there are limited places that this is done as well as the E coat process. The East Coast especially in the south would benefit immensely as traveling cross country loses a bunch of customers. Thanks

👍👍👍

You should get a go-pro camera and mount it on your head for hands free filming.

Very informative!!….what happened to Hugo on the caustic dive….lol

I'd love to know what chemicals you're using and if this would work on a small scale. I am in Australia and trying to convince the Minister for War that I need a Land Rover to restore and this would be a giant step for my adhd brain.

Ciao, ho scoperto oggi il tuo canale, molto bello. Sono perocurioso di conoscere i noli delle sostanze chimiche che usi, mai visto usarlo in Italia. Grazie!

Can you dip aluminum intake manifolds to clean the insides of them from carbon and oil buildup?

love these videos, what happens to all the debris , the rust , the old paint after you are done

It took me 3/4 of the video to realize that you had a little stowaway on the block. Did the little guy make it?

Did Chrysler make a 340? I know Plymouth did in the Barracuda. My brother had a 1970 years ago.

Looks great ! What happened to the Joker ?

Looks like you left some casting/freeze plugs??

What kind of alkaline are used to neutralize the parts after the acid dip?

In the first dip tank, for removing grease and paint, why are there plastic balls there? Is that to keep the evaporation of the tank to a minimum?

Why were 2 core plugs, the cam bearings, and a few oil gallery plugs left installed?

Bad news for you. Great news for us: All of your projects now must include before/after weigh-ins. (And I’m not kidding).

Do you use an inhibitor chemical in the acid so it doesn’t attack the cast iron after the rust is dissolved? Way back when I had to work for a living, when we acid cleaned big heat exchangers, we added an “inhibitor”, so the acid wouldn’t corrode the steel, just dissolve the mineral deposits. That was long ago, don’t know if technology is any different now…

Im looking to build a table out of a old v8 block is there any coating i can do after acid dipping?

Автор видео, старайтесь поднимать такой вес ногами, а не поясницей, поднимайте как штангисты и т.д. Поясница очень ценная вещь, к сожалению ее ценность начинают понимать только когда она начинает болеть. Берегите спину.

Can you do before/after weights on car bodies?

Looks great Dude keep going😊

Hello, greetings from Colombia. What is the name of the acids or products you used to wash the engine?

why didn't you remove the freeze plugs before dipping?

How long does that whole process take? And how much does it cost you to do the process on average?

It seems like you have I really would like to do. I wonder if there is a place in Kansas City that does t what you do.

I once asked a out acid deeping a car and you said, $2-3k. How much was this coat?

Hi , from where I can buy that pool and how many times in month or year should change the liquid?

yo dude! how much do you deadlift?

So here's a stupid question ... but I'm not a mechanic, just a guy who loves looking at and driving cars. 35+ years ago, when I was in college, I got a call from my sister that my mom had a heart attack and it didn't look good ... and I should come home. I had a six hour drive ahead of me, and I was booking it. About halfway home, I noticed if I took my foot off the accelerator, the engine shook terribly ... so I kept the pedal to the metal. Unfortunately, I got home too late. The next week was a blur. The car wouldn't run, and I eventually took another car back to college. Eventually, my brother-in-law told me that I had "cracked the block" but that he would get the car fixed for me - with a new engine. He did and I drove that car for another five years or so. The topic never came up again. So, when he said I had "cracked the block," is this the "block" that I had cracked? How on earth did driving my car fast (in the 1980s, fast would have been maybe 85 mph) crack this massive thing? Again, forgive my ignorance ... that whole event and the weeks following is still a dark hole in my life. Thanks to anyone who can answer this question.

New to the channel! What is the purpose of the metal balls?

This is ship knowledge I need what is the brand name of the alkaline bath?

Why didn’t you take all the freeze plugs out?
