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.

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.

Wish all machine shops, engine builders followed your process. Thanks for the video

[aztecahernandez]

One of the best Videos on how to prep a block. Thank you very much. Loved it. Now to paint my block and chase all the threads.

[disgustinghandsome]

He makes it look so easy. Very satisfying to watch.

[josephnubile]

Nice to actually see what I am paying for. Thank You

[raymondpetracca]

OUTSTANDING WORKMANSHIP VERY FOCUSED THANK YOU FOR YOUR NO NONSENSE, HOPE YOUR ATTITUDE NEVER CHANGES, BIG THANK YOU !!

[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?

[spraym]

Awwwwsome video. Just getting ready to take my 350 short block into the machine shop!

[bbigboy]

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

[prevost]

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

Removing bolts with the torque wrench. Nice...

[lazaromarino]

Awesome Really a well prepped block kudos to the builder

[jdsharp]

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

I like that shot looking down the journals

[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?

[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?

[morganpowell]

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

[muley]

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