Big Block Mopar: Explaining Hidden Power!

[@UnityMotorSportsGarage]

If it makes you feel better.... My Brand new Ford BOSS 351 Windsor block had the same problem it was out of square front to back. This started out as a completed shortblock.. had to square the decks on MIXED UP BOSS!

[@JustMoparJoe]

That’s wild! I have some 351w rods to show on Tuesday that are really bad factory castings. I had no idea!

[@UnityMotorSportsGarage]

@@JustMoparJoe I Had .010" taper front to back on passenger side and .012" taper back to front on driver's side.. but once again have seen this same thing on Dart Blocks, World Products... And most aftermarket blocks +.010" for you to do final finish work out of the box. This was a great Video Joe. I have said it in my videos. Quality Machine work is the corner stone to making good power!

[@JustMoparJoe]

I’m glad this block got corrected. It should make for a solid foundation.

I could watch this all day. Those guys are true craftsman. I spent 12 years in a machine shop watching genius at work. I’ve been a welder fabricator for 32 years and have had the privilege to watch and learn from great men like these guys. Not sure many of them would have let someone film them, this is pure gold. Great video Joe.

I'm also a welder fabricator, and I sometimes wonder if I should have gotten into machine work. Not being a union welder, pay hasn't been great until this past year, being promoted to supervisor (daddy daycare)🙄. And, I'm retirement age now, but plan to work for awhile yet

This is exactly why I always have the head(s) and block milled when I rebuild an engine, even a slant 6 . Ed explained the need years ago, and I had him mill my 170 cid slant 6 . (My 1st complete engine build) I can say it was worth it. I won't rebuild an engine without the complete milling being done

I got to see it with my own eyes. This one was pretty rough.

[@Mr39036ce]

Most engines will amaze you,so many parameters that are just barely " in the ball park" and it runs fine. You want to get full potential? That's why a good machinist isn't worth money, he's probably worth at tenth over the other guy you're racing. And just to touch on the slant 6 , there's a vid right here on KZbin of them decimating the competition in the short lived NASCAR compact car series. I think they were 170 cu.in. with the hyper-pac option. And if anyone has ever seen one they made a 225 aluminum block motor too. Had one in a 62' Lancer gt.

[@dirtlump]

With BB Mopars. that's why we keep our old manual Boring Bar around ? With the vintage legacy Blocks... we always Deck the Block "equal & square' to the main Bore FIRST.... then mount the Boring Bar directly on to the squared Deck to ensure it is then corrected/Bored perfectly 90* to the Main Centerline. The way to check that your Boring Bar is Boring straight.... is to Bore a hole .024"... then take a sharpie marker and draw 4 lines top to bottom in that cylinder.... then remount the Boring Bar a180* around and re-Bore thatHole at .026" or .002" larger. It should CLEAN all the Sharpie marker ink off !

[@JustMoparJoe]

That’s an awesome old school trick. I’ve seen the boring bar in action.

[@tomdamon7208]

Another awesome vid . Learned a lot . Most auto machine shops don't have the fixture to do the work those men do .

This is an awesome illustration of the relationship between the deck height and bore centers, by the numbers, chrysler slapped this engine together using a set of average clearances , I learned a lot, and I could also watch this all day, this is how it's done right!

[@JustMoparJoe]

Thanks brother! This engine should hit the 500 hp mark with stock stroke.

[@dartgts383]

I've seen that twist many times in the engines I've built , it's partly machining but it's also the block settling after the thousands of heat cycles. Any engine I have a hand in gets the decks squared, the shop I last use can square the decks and keep the factory stamped numbers on the id pad using a Rottler CNC.

Very good explanation of why shaving heads to make better compression don't always get the power gain expected and how the relationship between the deck and center line of crank bore can gain more power than expected also the importance of the relationship between both decks to each other,in other words it's better to get a block square than to just make the bore bigger and add compression

Good educational vid Mopar Joe.These things fall under the heading of "Blueprinting" an engine. The explanation of block deck height measurements being off "side to side" or "front to back" etc. is a bit redundant as "decking the block" is just that...leveling the deck. No matter where it's "high" or "low"...it gets "decked" just the same.

with all that machining will it affect how how the intake sits on the block and bolts to tge heads ? I hear you have to re-angle the gasket surfaces especially when you shave the heads to gain compression?

[@big3fan916]

Simple answer is yes

[@JustMoparJoe]

Every block is different. We didn’t take this one to zero deck. Just enough to clean up the decks and equalize them on both sides. It’s actually now close to factory specified deck height.

[@toverturf9097]

You can take quite a bit off the deck off a 440. Line bore the crank and deck block but Magnaflux the block first… especially around the mains.

[@SteveP-vm1uc]

Joe, did they align hone the block before this work? I have seen the raised area toward the center cylinders before, but never heard a good explanation why it happens. The best I can figure is that is an area that doesn't cool as well and over many heat cycles, sort of says high. Also, you are very correct. MOST machine shops not only don't want your cameras in the shop, but they also don't want you.. That is either because they have some secret machining or they are not great machinists and don't want anyone to know that!! lol.. It is great to watch and get the reasoning behind every move.. You can buy books with all kinds of tricks and explanations, but seeing it is another ballgame all together.. And ya know, we always knew that the factory tolerances were crazy, but here's proof.. And many say todays factory machining is far superior because tolerances are far tighter. Well, this is not the first time I have heard about LS blocks being way out of spec!

[@JustMoparJoe]

I elected to not align hone. I had them check and it was within tolerance. Much closer than the decks. I gained a lot of knowledge from being here. I appreciate Ed for allowing me in.

[@SteveP-vm1uc]

@@JustMoparJoe Gotcha... ~~ Ok, now the next engine you build you should step up your home prep before it goes to the machine shop. Things like easing oiling canals and water ports.

Just wondering if Piston ring Rotation is Desirable & what Really makes it Rotate ?? ....I always thought the usual Factory little bit of Deck "Out of Squareness" was maybe Design Intentional & Caused the slight Unequal combustion Pressures to start & Keep the Rings rotating ?? .......I sorta get the "Minimum Parasitic" Side-Thrust friction Losses idea you doin there..... if the rings Stop rotating from the near Perfect Piston Alignment, does that Hurt any Ring/Bore wear Longitivity ?? ......Thx for putting up another Great video showing some nearly unbelievably Machining Accurately !!

[@JustMoparJoe]

The rings always rotate, they say, until the engine gets worn out. The bronco engine I pulled apart and rebuilt had every ring lined up! Someone had to explain that to me. My guess is that the rings spin from following the crosshatch of the block from honing, and from the thrust of the piston into the outer edges of the bore.

[@ladamyre1]

Little known advantage those old Chrysler engines had was the diameter of the lifters. Chrysler had the largest of all the "Big Three" and this allows builders to grind cams with a faster rise on the lobe so they can achieve a higher lift for any given duration using a flat tappet lifter, solid or hydraulic. Roller lifters negated this advantage but in the days of the 392 Hemi it compounded along with that hemispherical combustion chamber that completely unshrouded the valves and let that engine breathe.

[@rustyh8806]

A lot of after market Chevy blocks use Chrysler lifters. AMC used the same lifter bore. .903”

That block may not have been nearly that far off when it was originally made. But after thousands of heat and Cooling cycles, cast iron can Warp a good amount. That's why updates that are sometimes put on Big Blocks are only done on blocks to have over 100,000 miles on them because the block is completely normalized and will no longer warp. Depending on the type of aluminum used, aluminum will Flex quite a bit, even each time it's heated up. But it eventually normalizes to some degree also. Why do you think on the North Star engine the rear cylinder head on the front wheel drive Cadillacs was always pulling the bolts right out of the block. Because Cadillac did not understand that when you put a steel bolt into an aluminum block. It has to be heavy coarse threads because of the fractal nature of aluminum. Once you do that upgrade on a Northstar Engine, the larger head studs will keep the heads from allowing them to warp and pull the engine apart. A well-designed engine, but General Motors could not figure out or would not take the time to make sure that the two-piece block was actually sealed. But once you get a few of the book worked out it's actually a pretty good engine. Horribly over engineered but a good engine once you get the bugs out of the way.

The number right beside the block number is the casting number yours is 5 that's good that's what you want 1 to 5 is best

[@JustMoparJoe]

Thanks Darren! Have a good one

[@tomreyn3610]

It’s what they call “blue printing”. As designed. Production just gets close. And it’s good enough. - great example. * So, is this measurement taken from the crank centerline? * Also, I’ve heard a lot of connecting rod ends do not run parallel. Is this serious?

[@JustMoparJoe]

Thanks Tom. The deck height is determined from center line of crank. His measuring tool was referencing the bar that ran through the mains.

How much did it cost for the work done?

Eric, I have a working deal with Ed. If you’d like his contact information, shoot me an email at [e-mail]

Thanks brother

[@stannelson2582]

Ok crazy question from a know nothing background lol. If we are being so perfect with the block. How do we make the head gasket maintain that perfectness. Won’t the head gasket undo what you just accomplished with making the block perfect. Head gaskets have variance don’t they or does torquing the head fix it. Sorry for my un educated theory/question.

[@JustMoparJoe]

Good question! I’m going with cometics that are multi layered steel. They are machined within.000010 tolerances and the multiple layers will adjust to some deviance in the surfaces. Fortunately for me, my block is now decked and my heads will be also. It’s as close as it could be without a cnc machine.

[@thomasward4505]

great video but you might try to make them a little shorter so people will watch all of it.

[@JustMoparJoe]

Thanks Thomas. I always put out my longer videos on Saturdays. That will give people the weekend to watch if they’d like. But if you’re an engine enthusiast, this should be a good one to stick around for.

i have a newer cnc machine made hunting rifle the bolt rails(in receiver) level the scope level the cross hairs are not strait up and down it off some way i had to move scope a little more to make it right, ok i measure engine blocks if i rebuilding them if not right fix it! square it right to a machine shop with my measure make sure i was right? if i right fix it! i went threw auto repair tech school in high school i went to drag racing & military I got sick in 1992 - 2018-19 i was told i was sick from & hidden by posin sumac in blood of blood cancer oh great i about to D but my uncle guy who blood thinner based on! from like 1984 in military don't count, there time for it to come out! the other stuff in my blood delayed it being found!

[@mikecrawford5331]

I like the machinist level trick but couldn’t a machinist straightedge and feeler guage check the deck flatness?

[@JustMoparJoe]

Yes sir. I believe I show that in the video. But it can’t check variance from end to end, or side to side. Then the difference in deck heights from the main bore could be more or less.

[@mikecrawford5331]

I will rewatch

[@tomstrum6259]

Don't think Typical (0.006") factory production Cylinder to Cylinder bore spacing Offset is causing you Any Measurable power Loss with Full Floating piston pins...Factory Mopars already have a Vertical 0.060" piston pin Thrust side Offset to Minimize piston Slapping which lots of builders Reverse (Causing even More piston Slap Movement) in Hopes of more power which has generally Never been Measurable.....Any Reasonable (0.003" -- 0.006") Horizontal Offset is Easily absorbed by the Typical 0.013" rod to rod SideClearance.....Now a Diagonal slanted Horizontal top to bottom Cylinder Offset Is gonna cause some weird Piston/Rod friction generating Gyrations wearing things out & possible Measurable power loss.....I've never seen any Dyno tests verify these specific Effects....Just my thoughts on a very Interesting & probably Not generally Measured by most folks.....I could be major Wrong thinking on this & I'm sure Minimum or Zero Horizontal Offset Is preferred......Big Thx for showing this......

What happens when this generation of machinists no longer exist?

[@JustMoparJoe]

I think the torch is being passed in several family based machine shops. For others, it’ll be a slow learning curve. Definitely a dying art.

[@carnalsupply]

Have to complement you Joe, this is an OUTSTANDING series of videos you’ve put together with Ed and Wayne. Feel lucky I found the same kind of craftsman out here in Vegas to machine my 512, who, like Ed and Wayne, walked me through the steps he took to true my block.

[@JustMoparJoe]

Thank you! These are good guys at got have a passion for their work. Doesn’t happen much anymore.

[@jerryhatrick5860]

Just flip the piston lmao.. Huge power gains, ask ugly Tony. Used pistons and flip em, works every time a lose motor is a happy motor. Ugly Tony know best. A used cam helps also. As well as installing it with a hammer. Oh and add nitrous. So it gets down the track top notch hahahahaha.

[@JustMoparJoe]

😅 man that’s tough

[@dynodon100]

Just make sure that your block is true before you open up the block..020 ,.030 , or.055 ...whatever.

[@JustMoparJoe]

Ed’s machine made this block true to the crank alignment.

[@mikebartley481]

What about heating the block and then take measurements if you really want to be accurate.... Lol

[@JustMoparJoe]

This is a climate controlled shop. But the engine has heat introduced when the machine starts cutting on it. There’s too many different times with temperature variance’s. The expansion rate of the engine should be the same.
