How do WE Balance YOUR 383 Stroker?

Love it, that you’re pulling back the veil and showing more in depth engine work that most people never see keep the videos coming.

That's my goal! Help our customers (and the customers of our peers) understand what really goes into quality machine work.

[@SnoDraken]

I used to run a gas turbine repair facility and we'd spin 2000 lb fully bladed compressor rotors in a vacuum. I saw one jump off the rollers once, blew through the roof of the chamber, crawled up the 40 foot shop wall and land about 200 feet into the parking lot. Every time a see a shaft spinning now I pucker just a little bit. Great Job guys, you do great work!

I knew someone who bought a salvage yard 400 SBC, but didn't want to spend the extra $25 for the flexplate. Used the old 350 plate instead. Yep shook like a paint mixer!

[@JAMSIONLINE]

Lol

[@bobjones37450]

I knew a guy that done this as well. Put it together and drove about a mile. Broke 2 rods and spit the block up around the cam. Also one of the rods put a nice inspection hole in the side of the block.

Bought a 77 Chevy from a friend in highschool. Had a 400 small block... they said... somehow my other friend found a 400sbc before i bought the truck. Yep you guess it they swapped a 350 in place of the 400 and never said a word to me.

I had NO IDEA all that is involved. And no wonder this cost what it does. I will now be satisfied vicariously watching "real pros". Thanks men, enjoy these videos.

[@richardjurgens4511]

Nice work, fellas. Hats off to the Cleaning Guy!!! I used to balance rotating assemblies for pumps, turbine’s etc, but not engines. Nice to see the care and attention to detail here.

[@justinkorpela7955]

It is a great enjoyment to see fathers and son to share the same passion and the real professionalism they put into it on every level. Then you hear them say: “the cleaning guy”, if one would just imagine that the cleaning guy is the soul and matter of the whole operation.

[@tobiasbostwick9002]

I knew that balancing was detailed and time-consuming, but I didn't realize to what extent. Thanks for the enlightenment.

[@Charger1908]

Boy I sure enjoyed this one! I’ve been building performance engines for over 50 years and I always farm out the machine work (obviously) and this was the first time I saw how it was actually done. What a great learning video. Kudos

[@odl21]

Why ‘obviously’? I also build performance engines for myself but can do everything except grind cranks in house including all machine work, head work, flowing, dynoing…. With time and care I can do a much more precise job than you could pay most people to do.

[@DodgyBrothersEngineering]

@@odl21 there is so much information on the internet these days on how to build things, that you no longer have to rely on a performance shop for some of these tasks you did when I was a young fella. But I don't think I ever put an engine together where I didn't at least do a Clayton's balance on it (heaviest piston to the lightest rod etc). Same with matching rings to bores. Sometimes you don't need fancy tools, you just need to think and have patience to do things right.

[@Charger1908]

@@odl21 Well that’s just dandy for you!

[@keithfork8663]

So much handwork done. Nice tools and computer.

[@ni_wink84]

I sure miss doing that stuff! From what I remember it was pretty typical on the one piece seal 3.750 cranks to have to drill quite a bit in the exact same spot, if memory serves! Great job love the videos

[@craigm.9070]

Thanks for your time guys! Way to sneak up near zero; I hope your balancer doesn't upset the apple cart. Looking forward to the assembly!

[@db3170]

Thank you for your open honest presentation have a great day gentlemen.

[@GroupWar]

It looks like if you just removed the counter weight bolted to the flywheel it would just cancel out the needed two big holes that you made on the right side of the crank, they seem to be both on the same axis. Very good and detailed video, I just love watching you guys, thanks and greetings from a subscriber from Qatar!

[@roughboygarage1475]

I thought the same thing. Would've took 1min to pull it off and spin it up. I've seen those cranks come in both ways. Neutral that needed counter weight and external balance that came in neutral.

[@ripn929707]

That weight on the flywheel is set out quite a distance from the crank center line. The weight calculated is based on the diameter of the crank balancer diameter... in other words, it wouldnt work to remove that weight. It would make a bunch more problems.

[@bigbelconut]

Nice balance job. My best balance was .02 and .03, on a early 350.

[@duanedale2505]

Nice explanation. Remember having a crank for a blown alcohol engine balanced which they used Mallory plugs for balance

[@nfinitymarine4466]

It's good for gearheads to see the common machining processes in real time. It makes it very easy to see that your machinist didn't charge enough for the work he did. Add on tooling costs and realize the poor guy is giving his work away.

[@johnnoehl8917]

You guys got room for an apprentice? I’ve got a camper on my truck and I’d drive to your shop and stay in my camper just to be taught by you 2. I really love your channel.

[@halletts1171]

Good job! I have sent many a crank to be balanced and always wondered how it was done. Thank You!

[@kaseysimons128]

Enjoyed watching the process

[@donscott6431]

“Knife-edge” that counterweight. We used this technique in our engines along with a “crank scraper” metal strip that kept more oil in the bottom AND slightly lessened parasitic power loss. We also used “Mallory metal” which is much heavier than the crank material. Holes would be drilled into the counterweight parallel to the crank and mallory metal would be pressed in and tacked.

[@Kaus5221]

Thanks again for saving my LM7 block its about to run for the first time in the BMW @Jim's Automotive Machin Shop, Inc

[@countryboysteve]

I've found that balancing the clutch cover is something many people overlook. I've had some as much as 20 grams out

[@grahamrothermel5139]

100% agree, I usually take the pressure plate/cover as part of the rotating assembly when I have things balanced for my personal stuff or customer builds.

[@abc-bm8pl]

Did you test the balance with the weight removed from the flywheel? Would it have been better to knock some weight off there to save drilling the crank so much? or is that a normal amount of weight to remove from a crank counterweight?

[@Airwolf1971]

You want to do it from the crank so if in the future you have to replace the counterweighted flex plate or flywheel with a new one the assembly will remain balanced.

[@tomstrum6259]

Great Textbook balance Job guys,....Even almost running out of Counterweight, Youmade Perfection seem easy !! ..... Show us the Job one when the Hole needs to be in the Middle of Empty space & you have to really Work for your Money !!

[@frankwoodward1231]

Or just off the edge of the CW. Can't remove weight switch to add and no place to add weight. Tweener my ex boss and I called them! Lol Those SUCK! Fortunately the crank manufacturers have improved that..... mostly.

[@e-racer4673]

Did anyone else see the front of the crank where the harmonic balancer goes wobbling? I would say that has a whole lot to do with the Burlenson of it. It would be just like a bent rim. I work in an engine machine shop for six years actually a little over five years and I loved that type of work. But life happens and I got old. I wish I had stuck with it. I was about 25 years old when I started and worked till I was a little over 30 at the machine shop. I loved boring and sleeving blocks reconditioning rods, and balancing them.

Half my working life “on the tools” vs half in an office and I finished up with 18 months making carbon fibre parts for McLarens / Aston Martins. If I could start again, butchers and machine shop (assuming I had the talent) would be my choice. The happiest I’ve been at work was always where there was something to physically show for it at the end of the day. Fantastic video guys.

[@FriendlyFire71]

Awesome video! Learn something new each time I watch you guys work. Watching the metal removal and thought I'd suggest an inexpensive shop vac be used to pull those chips away and maybe reduce cleanup time and help keep the area chip free.

[@Tex777_]

I'd mark the pistons and rods with letters instead of numbers for weight matching purposes just because if that writing survives and you're not the next person in it, it might be a little confusing. Then reserve the numbers for the cylinders they go in to. 😀

[@georgebettiol8338]

The markings are to serve the machine shop whilst the parts are in a pristine condition. If the engine is later disassemebled, a competant mechanic will always mark the piston-rod assemblies before they are removed from the engine - that's standard practice that all apprentices are taught.

[@karroome]

Awesome as usual guys One Q?, what would happen if you removed that counter weight from the flywheel befor drilling. It sems to line up with the big hole you had to drill Love your work👍🏻👍🏻👍🏻

[@georgebettiol8338]

If you remove the flywheel it may improve the situation - not sure. However you then have to balance the flywheel as a 'stand-alone' item which adds cost. My preference would be to balance crank, flywheel, harmonic balancer and clutch pressure plate as seperate items so the latter three can be balanced seperately if they need to be replaced during the life of the engine.

[@nhzxboi]

I have the same passion for balance. But, back in my crankshaft grinding days, I noticed that quite often the crank pins were not exactly on the degrees that they were supposed to be. Essentially I'd treat each pin(journal) as it's own sphere....it may have been off by 3 degrees maybe. But, no way can grinding make up for that. Twist over time? Bad OEM machining? Beats me. But, after seeing that with crankshaft angles, it made me regard balancing parts as not being all that important. There is far more to balancing than just weight of pieces. I was weighting rings when the journals were so far off seemed sorta silly.

[@alanmeyers3957]

Absolutely correct, I never see this brought up before, especially on small block chevys.

[@kevt5090]

Very interesting! Thanks fur the explanation.

[@billhatcher2984]

I enjoyed what I cought was the last half or so but as long as I'm learning I'm in good video I think I'll stick around 👍

[@jacquespoirier9071]

on a production engine rebuilt with production parts, just equalizing the weight of the pistons and of the connecting rods usually makes a very perceptible differenge . I always equalize the weight of the piston /pin / conrod assemblies within 1 gram when I rebuild a marine engine, it makes a very perceptible difference.

[@christophercastor6666]

Good on ya boys!

[@JeffRobb-u4o]

Nice work, great information! Do you worry that drilling holes weakens the crank? Could you knife edge grind the material off and achieve the same result? How will the pressure plate and clutch disc affect the balance, should that be added in? Thanks for the great videos.

Do you guys ever knife edge the weights to help with drag/windage issues? I had an autoshop teacher who swore by it. Our schools 71 Demon ran 12's with full exhaust.

[@1320pass]

I think you just made an internal balance recip assembly 'kit' into an externally balanced assembly. Just remove the balance pad off the flywheel and keep both ends neutral balance. (smaller drilling to get your ends to come in balance) Or am i (probably) missing something?

[@frankwoodward1231]

If they were to spin the finish balanced crank without that flywheel weight or flywheel for that matter it would be out if I remember right around 160grams, ADD weight to the counter weight. And it will mess the front up a fair amount also. Surprisingly.

[@madewithscraps]

You didn't miss anything at all. Well stated.
