Amazing craftsmanship. I love machining. I just think this type of work is like Superman with his cape coming in to save the day and right the wrong! I am so excited I found your channel and subscribed today. You deserve 200000 subs with your pleasant demeanor and awesome machining skills you and your shop do! I am a fan now for sure. Please keep them coming!
The average for the factory Mopar blocks I have worked on is 0.012” end to end with a little bit of unlevel decks. The Chevy blocks have been closer to 0.017” end to end. Definitely worth the effort and use of the BHJ Block Tru fixture.
This video teaches me that you need several qualities to be a competent machinist, some of which are the desire to be competent and do quality work, buying quality tools, keep your tools well maintained within tolerances, understand why and how to use the tools competently, and understanding what you are suppose to achieve with the tool on behalf of your customer. Decking two sides to different planes, neither of which are parallel to the centerline of the crankshaft denotes incompetence or neglect of the customer. Thank you again, Mr. Powell. I’m fascinated with your work and enjoying the videos a great deal.
I just so appreciate your dedication to perfection and willingness to share your knowledge! I’ve got a BBC 454 with 990 heads in my flat bottom boat. When it come time to build that motor I’ll reach out!
You are a very knowledgeable talented and experienced machinist I hope everyone who watches these episodes realize how much work and knowledge goes into an engine. Thank you for sharing your awesome videos.
You are the southern version of Steve Morris! Your skill and knowledge is amazing and content is awesome. I want to build a 68 Camaro and when it comes time for an engine I’ll come see you. I’m up in Charlotte so you aren’t too far a drive from here!
Had a brand new 502 was .030 out. Right where you measured. Worst block ive ever seen. I have that same surfacer. My dad made a real nice touch off indicator for it. Like the DCM machines had/have. Great content in your vids. Subscribed!
Just to expand on how precise Daniel’s machining and machines are: if he was removing .0001” (one thousandth) of an inch on each pass, it would take him 32.25 passes through the machine to remove just 1/32 of an inch, the smallest graduation you can read on most tape measures. Just amazing to see this repeatable precision, from a man who gets miffed when he “only” gets within a thousandth of an inch. No cornbread here 🗜️
It just makes for a frustrating day you have to start out fixing other peoples mistakes that shouldn’t happen. It happens because of one simple thing laziness
I have yet to see you make a video of a engine build your's or someone else that has been a good engine sure would like seeing you built a good engine with no problems
I just had to say something about this block as you have shone that the same was done to both sides. Being no one knows the history of the block other then someone cut the block this way. Can I remind you of the 348 and 409 engine? No 90-degree on the deck. If this block was at one time used in a class of rules and it had to stock. Everything that you can do is used that is not checked. If you cut .010 taper here and .010 there it will equal to .020, who will see this? This will change the valve angle entering in the cylinders. How much power it equals only those that do it know. Take a crank and turn it under .010 and add .005 to the stroke. Yea someone could not grind a crank right. You should be getting the point by now. For me in my younger days 1970-ss I did run NHRA Stock Eliminator racing. I had a 427 - 425 hp BBC - B/S car that could run .200 under the record. I could never set a record with it or make 2 runs back to back. Because new rear gears would only last one run (3700 lbs legal weight). The rear had to be stock parts. It’s amassing how many little things you can be done to make power that most people will never know about. Today I’m legally blind so I don’t see all the screw-ups that I made here in 2hrs. You’re doing good work, keep it up. Ralph
I've always wondered how they reference the face to machine a block like this, great stuff! One question though: How does the fly cutter only cut on the leading edge? Is the tool or spindle at a slight angle for this reason?
How is the RA the same at the front of the bank to the rear without the machine head not completely passing over? Is there a slight axes to the machine head which doesn’t allow the cutter to make a return cut from the back?
If you’re going to deck an LS block There’s a high probability you’re going to end up with piston above the deck. I do not know why GM did not provide service ability margin.
I have seen OEM blocks with the piston 6 or 7 thou out of the hole. Do you know who did the machine work on this block, the first time? @@powellmachineinc3179
On a 90* V engine. THe head surface should be perpendicular to the crank. Once he sets up the cylinder boring machine (it sits on the head surface) that will ensure the bores are perpendicular to the crank.
I stopped fully relying on the BHJ fixture! The cam bore can be off from the factory and the decks actually be close to square. Simply stated it's just another tool on the road to perfection that you can use in coordination with other things. By it's self NO. Use it on an old gen 1 sbc and you'll be off in neverland as the chamfer on front cam bore was always off center on 80% of those blocks. I machined a puck instead and wasn't thrown off like the bhj cones. If the BHJ cone is off .001 just think how far that plate edge can end up off!
What are those eight round pieces sticking up out of the valley area? I’ve never seen anything mentioned about them anywhere. Is it just leftover from the casting process?
LS9 were known for a poor deck finish, very rough finish. I'm Wondering if someone had surfaced it once before to clean it up and milled it incorrectly.
@@powellmachineinc3179 I'm not claiming to be a machinist (I wish I could do this stuff btw). Some of the camera angles from the previous video make it look like the block surfaces are not the same as the fixture. What would be the reason that you wouldn't do the decking procedure first? Just curious. Thanks
@@leeanthony9495 The block in both operations is fixtured from the cam/crank centerline, the main bore is always the first op.... it is always the datum point, we always save the decking for near to last as possible to make sure that surface stays pristeen
Im curious, does that fly cut leave a back cut or is it set on angle so it does not back cut and if so does that technically leave a dip down the center of the cut seeing as the fly cutter is round?
I suppose the "dip" would not be visible when indicating from the cutter head sweeping back and forth. Would need to use a precision straight edge I suppose.
@@powellmachineinc3179 I have asked other people that do this type of work and they just did not understand how it would technically have a dip down the center since it has tilt to avoid a back cut and it started to make me question my self haha thank you for the fast response, you have a high quality shop and do high quality work the attention to detail is great!

Factory doesn't check blocks. It would take forever to check each block out of thousands and thousands of blocks. Its the machinist that setup the blocks for cutting and drilling. They are set up wrong from the start.
It's nice watching a knowlegable machinist using good equipment working magic. ;)
Thank you sir!!
Goes to show that just owning the equipment is not enough. You gotta know what you're doing, too! Great explanations
I appreciate that!
Yep. Only time will give experience.
@@mvg-1776 this like most isn't a trade were a person learns a skill on the customers dime
What I like about this: what a clean, tidy and organised the workshop. Indicative of a company that's going to do a good job.
I understand how you feel about tolerances. Some guys are okay being within specs but I always feel better getting it as close to perfect as possible.
Absolutely
I would’ve been worried about my setup if I saw the block was that far off. Great video love to watch a craftsman at work.
Thanks 👍

Very good explanation of setups & machinery techniques 👍
I've used BHJs tooling on race blocks for IMSA prototype V8s, good quality and built solid.
Absolutely
Nice job Daniel.
Thanks for sharing. 👍
My pleasure!
Love the finish after freshly cut
Impressive workmanship.
I never realised how inaccurate they are at the factory. Great job. I just subscribed.
Thanks for the sub!
It must be one hell of an expensive, or rare block to go to so much trouble rather than just replacing it.
We do this to blocks often
It's called blueprinting for a reason!
I used Block Tru fixture when squaring up and zero decking my 454. Man those things were bad from factory.
Thank you for your knowledge and video's USA 🇺🇸
Thanks for watching!
Strong work
It just makes for a frustrating day you have to start out fixing other peoples mistakes that shouldn’t happen. It happens because of one simple thing laziness
Absolutely 💯
Hmm I wonder how the bolt alignment will be after all this cutting and the new angles they will be intersecting at.
Block True for the win.
Definitely
Wish I had known about you 10 years ago before having a shop ruin a lsa block and another ruin a lsx iron block.
Are y'all from SACRILANA or NOCRKLINA? 😊
I know on the Gen 3 stuff, the pistons are normally .006-.007 out of the hole at TDC from the factory.
I have yet to see you make a video of a engine build your's or someone else that has been a good engine sure would like seeing you built a good engine with no problems
Yep, unfortunately we get alot of "fixing another shops mess" we have some Virgin builds in the pipeline, just time.... we are booked out 6 months
Actually its only 5 or 6 off square but you know that !
Correct, t.i.r. is .011 so half
Right on the money with every comment. You know your stuff !

I've always wondered how they reference the face to machine a block like this, great stuff! One question though: How does the fly cutter only cut on the leading edge? Is the tool or spindle at a slight angle for this reason?
Yes, the head is tilted a couple thousandths
Wasn't that angle decking an old school thing, so you wouldn't have to do any intake manifold manifold machining?
Do those blocks have steel sleeves that require special precautions when decking?
How is the RA the same at the front of the bank to the rear without the machine head not completely passing over? Is there a slight axes to the machine head which doesn’t allow the cutter to make a return cut from the back?
I can only assume you don't understand how a surfacer works.
@@powellmachineinc3179 guess not so much.
If you’re going to deck an LS block There’s a high probability you’re going to end up with piston above the deck. I do not know why GM did not provide service ability margin.
Yeah, I believe that's why they ended up at a .051 gasket, we have seen oem blocks at zero,
I have seen OEM blocks with the piston 6 or 7 thou out of the hole. Do you know who did the machine work on this block, the first time? @@powellmachineinc3179

We refrance the pan rail to qualify
You can get head gaskets made to a specific thickness? Would that also mean the intake manifold would need a thicker gasket?
What are those eight round pieces sticking up out of the valley area? I’ve never seen anything mentioned about them anywhere. Is it just leftover from the casting process?
Those are the ports for the DOD System if so equipped.
How much is too much to deck a block
After decking the block and heads on a LS . How do you check and correct the fit of a plastic intake ?
We gone bak aout
How often do you have to dress that grinding wheel?
LS9 were known for a poor deck finish, very rough finish. I'm Wondering if someone had surfaced it once before to clean it up and milled it incorrectly.
Yes
Do you use a pcd or cbn know pcd for aluminum but with the steel sleeves in there or just take a little at a time with pcd 🤔 run same rcm 10
With a bimetal deal we use cbn
What are you thinking about the intake and head ports matching up?
We will mill the cylinder head intake face to the correct dimension for intake alignment
@@powellmachineinc3179 good job man.
You don't buy this machine at Walmarts. Only thing this shop doesn't have is an engine dyno. Sick.
We have one, just haven't had time to finish the dyno room
Depending on the position(angle) of that needle the measurement will no longer be accurate! But anyway out is out and it is clearly out.
That's pretty cool. Does the blueing provide any lubrication?
Na, just visual, I do spray a lubricant to help with aluminum sticking to the insert.
should this step be done first? does this mean the head bolt holes you drilled aren't 90* to the block?
Really? Maybe you should watch that episode again, what was the block fixtured from when the head bolts were done?

Won't taking so much off the hight of the deck make the pistons stroke to long ? Or possibly cause the head bolts to bottom out befor thay are tight ?
Na, we are only talking. 010
small bump in compression will help a bit.@@powellmachineinc3179
What is the maximum depth of cut per pass do you normally limit yourself to?
Most normal stuff. 003.005, put I could take .030 in 1 pass, just never need to
