SBC--BLOCK PREP & MACHINING

[@sjhanson1690]

Did a fine job young man. I would try and talk the boss into getting you a dowel pin puller, that was the only part that didn’t look professional. I’m a retired engine machinist myself and pretty much seen it all. And hey, if you have an old small block Chevy oil pan and timing cover laying around, just silicone them together and instead of taping up the block, use those. Here is another secret we had in the shop. First get a hold of a chunk of wax. Just crab a couple nice size candles. Remember that bolt that was broke off in the bell housing? That was the perfect kind of broken bolt, or galley plug this works on. Just get your torch and get the bolt, not the block, red hot. Just when it gets red, take the candle and push the big end of the wax onto the red hot bolt. Just for a one-thousand one. Then grab a vise grip or even a pliers cause it will come out that easy. Try it and let me know. We just used a block of white wax, but it doesn’t matter. The melted wax seeps down in the threads and almost pushes the bolt out. When I first learned that, (not going to tell you how long ago that was) I was just shocked.

[@ronwong7030]

You should use a Thread Chaser to clean the threads, not a thread tap. The thread tap will remove metal making the thread larger. The Thread Chaser is the same size as a bolt and only clean or realign the thread.

[@PatandDoopypoopy]

Thumbs up Ron. I used to have to install a lot of Healy coils at my shop because people would use tabs to clean threads and then they would wind up stripping them out Thank you For mentioning a really Is important step to do correctly

[@dennisropon2201]

very nice work, enjoyed watching the video. Great job !

[@jdsharp4033]

Use a dowel pin puller, if you’re not decking the block you could raise up some nasty burrs with those vice grips

[@prevost8686]

I love the smell of WD-40. Still the best as far as water displacement on metal goes. Thanks for the video.

[@albertgaspar627]

[@SOLDOZER]

Whats the purpose of these bolts that are directly under the head @ 3:58?

[@6.8SuperDutyDriver]

Good show!

[@John-ri7xl]

very nice job

[@morganpowell2999]

Honest question, does that surface rust inside the motor not cause any issues?

[@bananasEveryday]

Hi, I have a question for you. Would it be better to use a thread chaser instead of a tap for the head bolt holes?

[@b.c4066]

most manuals say that because if you do not have a feel for the tap and it is actually cutting threads vs just cleaning them. due to manufacturing tolerances you could easily cause more harm than good. so for a novice most manuals suggest a thread chaser. a guy doing this 3 times a day 5 days a week gets a feel for it and can tell instantly if the tap is cutting vs just clearing the threads.

[@DeliriumElectric]

Most relaxed I've been in weeks. I was waiting to see it washed after the machining. Do you do anything about all the rust in the galleys?

[@muley180]

Excellent. What sealer do you use on expansion plugs and other plugs in the block? Thank you.

[@Nowayjose-z2r]

Removing bolts with the torque wrench. Nice...

[@bbigboy01]

Nice video. Would you explain how you reference the block being leveled, before starting any machining?

[@ridinrancher9443]

I saw it mentioned the factory deck was unevenly cut. Is that the case of could heat from overheating caused similar unevenness?

[@lordsauto]

Got my block back from a machine shop. Core plugs cam bearing and galley plugs were installed do i have to clean my engine again? Im just not sure. Thanks

[@dk2614]

I like that shot looking down the journals

[@markclough9000]

Are you going to hot tank it get some of the rust out of it

[@randy1ization]

sir I have a question maybe you can assist with,, here goes.. ,. Ok the chevy small block oil system from the research ive done ive read that the SBC uses a check valve in the oil filter housing that works on a pressure differential.. so,., I have read that a chevy small block with normal oil pressure is around 10 to 15 psi at hot idle.,. If a high volume, oil pump is installed, with no changes to the oil bypass valve in the engine, will the oil bypass the filter, and go thru the check valve instead.. also. when rebuilding an engine, how do you service or replace the oil pressure bypass valve... thank ye! would love to see a vid on the intricacies of the small block 88 to 94 oiling system. I see alot of vids where people buy a GMT 400 series truck, see the 12 to 15 psi oil pressure at warm Idle and panic. they put high flow high volume pumps in and feel they have taken care of the "problem" . but im wondering if they are creating a problem.

[@Van-yc6mr]

Well done!

[@bstortford196622]

What is the average cost for magna flux, re bore and decking the block?

[@jasonhattrich3521]

Don't forget hidden galley plug in the rear main...no oil pressure if missing.

[@sgtokie]

well prepared video. would have been nice to see you remove that nasty casting flash and i am going to assume you washed the block after machining. don't forget to chamfer all your bolt holes and cylinder bores after machining. just a suggestion, dump the oil galley cup plugs, thread for pipe plugs and drill a 1/16" oil hole.

[@SOLDOZER]

Mine survived 40 years with just plugs. Plugs are just fine.

[@lesbratton]

​@SOLDOZER Good for you, not everyone goes the easy route.

[@JesseSeg84]

How often do you install deck plugs with drilled water passages on your sbc builds?

[@hydroy1]

No aline hone/bore on mains ? Free horsepower. On my motors I spend the extra time to drill & tap the oil galleys on both ends as them factory plugs can leak. Also use & let set up Indian head gasket shellac on all freeze plugs or they might leak for a few heat cycles. Did you hone the cylinders for Molly rings or cast iron ?

[@inscoredbz]

I have never had a block with that much done to it as far as cleaning all the threads. They leave that up to us. Looks great. One question though, why did you take the torque plate off and re-torque it before the final hone?

[@buyamerican3191]

I noticed that you clean out all of the tapped holes with a tap, is that better than a thread chaser?

[@PeggyParrow]

Use a slide hammer tool to easily remove pins .They have kits with a variety of cones .

[@trlprk]

I am totally mesmerized

[@TinkerPrepper]

Why is the "torque plate" used while honong?

[@MrLeeCamaro]

This is art. Great video for sure.

[@trevorarens7143]

Does it automatically tell if there is taper? Wondering why the hone stayed at the bottom of the cylinder for a few strokes??

[@robertankney5480]

Now if you are running head studs, would you use studs on the torque plate instead of bolts?

[@SOLDOZER]

WHUT?? This is a block and has nothing to do with heads or studs.

[@Dougarrowhead]

⁠@@SOLDOZERhe has a good question and you obviously don’t know anything about engines or what he is talking about. Studs pull on the block differently than bolts and distortion is real.

[@t.s.racing]

Ex Nascar Engine Builder here, Robert the answer is unequivocally YES. You always do your best to simulate exactly how the engine will be final assembled. Right down to the lubricant used on the threads of the studs. The person doing the final assembly should repeat EXACTLY the procedure done during machining. The torque, the steps, the lubricant, and type of fastners, all recorded on a build sheet so that final assembly is the same as the machining process. T.S. RACING 🏁

[@bradleyleben7785]

Excellent job!👍

[@randy1ization]

GREAT CHANNEL LIKED AND SUBSCRIBED !

[@randy1ization]

I noticed no cross hatch hone.. ive never understood the cross hatch theory. is a horizontal etch the way to go?

[@dk2614]

Interesting you put a head brace on for honing. Does it just help the hone stay true in the cylinder? 30 yrs ago I remember seeing a guy with a Christmas tree on an electric drill!

[@JacobVillemain]

Yes, it simulates the stress caused by the cylinder head fasteners. The stress distorts the bore, and then I can hone the cylinder perfectly straight.

[@FORCFED]

Where's this shop located? Still on it's 4 years ago lol thanks

[@justinfore1640]

the cam bearing oil holes supposed to face towards the crank so the holes line up for oil ?

[@thehappytexan]

I thoroughly enjoyed this video. I have a question though, with the 5 axis cnc machines being produced now, what are you thoughts on using those with preprogrammed block blueprints to potentially correct bore spacing and other factory casting/machining flaws? I know boring blocks by centering to the bore has worked for decades, but I would think having perfect bore spacing would be ideal for reducing piston scuffing and rod deflection.

[@flinch622]

No perfect in machining: just tolerances.

[@mikeandmona]

Cost of new equipment is extremely expensive. Must do enough business to justify purchasing new modem equipment

[@carsmytruck1]

The machine that can do blueprint bore spacing) lifter bores and such cost around $250,000-$500,000. But customers complain about $200 to bore and hone there block. Figure the math out. I'd rather not have my grandchildren still paying on the equipment,

[@thehappytexan]

@@carsmytruck1 can’t argue with that logic one bit.

Not so much a comment as a question...... How do you know that you are cutting at 4.025 say +/- .001 after the first bore? when I seen it checked it was after all four bores were roughed out...???

Howard Henry I first bored it at 4.010” to check the calibration of the cutter. If the cutter is set at 4.010”, but it only cuts 4.008”, then I know if I want my final rough bore to be 4.025”, I need to set the cutter at 4.027”.

[@lesbratton]

Notice he reinstalled oil galley plugs with drive in plugs, instead of tapping holes and installing threaded plugs. Might as well and gone the extra distance and done it right.

[@mitreswell]

Somebody enlighten me. Why is the torque plate used for the honing but not for the boring? I'd think it's more important for the boring where material is actually being removed and it's critical to get the bore correct, rather than the honing where the cross hatch is put on the cylinder walls. Seems all wrong to me and I don't get it.

[@JacobVillemain]

It doesn’t matter while boring because I will come back in the honing phase and correct the block.
