Chemical dipping a Chrysler 340 Engine block

Today I’m I’m getting this old rusty Chrysler 340 engine block down to bare metal. I’ll be taking all of you through the proprietary 3 step chemical dipping process we use to restore it to its former glory. The process usually takes a couple weeks. I was on vacation in the middle of this block being dipped so I missed about 2-3 acid dips.

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 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.

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.!

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.

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

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

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

[bikinglikebecker]

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

[rumrunner]

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

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

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.

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

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.

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

[jimboalogo]

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.

[zackjones]

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

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!
