Blueprinting For The Home Engine Builder - How To Get The Most From The Parts You Already Have

[@oldtimerf7602]

Tony, I believe you have found your "true calling". This channel is exceptional in that you give max wisdom with minimal dog and pony show. No 2 minute intro nonsense, no manufacturered drama, just straight to the point info and wisdom. God bless you.

[@oldtimerf7602]

@@DanEBoyd Yeah, but only rarely. 95% of the vids are what I just described. And let's face it, getting a look at unobtainum old cars owned by cool people isn't the worst. Beats 2 minute intros with horrible techno nonsense "music" through the whole video.

[@nicholasagnew2792]

exactly my thoughts

[@kcav5374]

As a block machinist I worked for four different current or former Pro Stock racers. and what engine Builders go through to give a customer a good high horsepower, long lasting engine most people don't even have a Clue! A younger fellow I know tried to tell me that "Building an engine is a no brainer!" Oh how I wish he'd try & build his own race engine! lol

[@DrewLSsix]

I'm not professional builder but trying to talk about the details in my niche Mazda market is frustrating. People seem to think these things only apply to old American engines. And they keep breaking pistons after they shoot down my statements on the importance of clearances.

[@oops1952]

My favorite was the boys that added up the gains they'd get from their after market parts, slap the thing together, and brag about the 500 plus hp they had. Hmmm

[@LSswapGarage1]

Sad nobody wants to pay for your time anymore though... they just expect hours of work and perfection for free 99

[@tinkersspeedshop8401]

I have found that trial and error, tinkering experimenting and most of all listening to experience does make it a no brainer. I have assembled $75 engines that screamed, and ive also fallowed formulas that i could beat with junk. Engines are a wonderful thing, but its simply just science

[@tinkersspeedshop8401]

@@oops1952 Yeah ive always laughed at them. I have a group of younger guys who say my car is fast. 🤦 Its just a stock early a body with a stock 360, the same engine formula that engine master deemed "the worst engine ever at west tech performance" 🤷 It aint fast yet. But my next engine, thanks to tony, will be a chassis breaker.

[@shadowpatriot1948]

Man! You are so right Tony. I have spent forever putting my slant six together. Piston height, rod length, cylinder head alignment, pushrod length, cam timing, it's never ending. Sometimes I had to force myself to take the proper steps and not cut corners. And that's not mentioning the worst part, finally starting the engine. A whole new level of fear factor.

[@BigT27295]

I know thats right . It's like damn i spent all this time and money . Lawd Don't let me fu€K this up now.__

[@Z_732]

Hahaha.. truth! I've seen a hundred + hour build blow in 3 min flat. I get the jitters just doing a basic lol. Call it PTSD I guess. It wasn't even my engine that blew.

[@flinch622]

I can relate also. Thinking about my last build, a short list of stuff I had to sort, above & beyond: resize inside diameter of crank sprocket [only that one area of crank was 0.015" larger than spec as received for no apparent reason], knock 0.012-0.013" off pistons to get zero deck, measure/match grind areas of cylinder heads for equal cross section [pinch point & runner openings, the latter forced by a "gasket match" that left steps like a 3/8" end mill tends to do on a rough pass shaping], regroup on springs & retainers [after finding first set were a little off for the cam selected], and haul the block off to a machine shop for mains honing because they were too tight as delivered [as in off the chart on plastigage]. That leaves out a couple things [like lash caps used to correct rocker geometry], but these probably ate up an extra 40+ hours beyond a simple clean/measure/assemble with no real problems. I am no pro - just a home gamer. That short block gave me a headache - especially after seeing pistons had to come back out. I assembled that 4 times before moving to heads.

[@elmerfudpucker3204]

Wow! Gave me flashbacks lol. I learned how to use micrometers, calipers, dial gauges, and bore mics as a pretty young lad, by measuring assemblies for my uncle in his shop, as he was building dirt track engines. I took right to it, and I just had a flood of memories come back, as it was in the late 60s and 70s that I was first learning it. Spent many days and nights sorting long rods to short piston pins, and so on.

[@sewing1243]

The late former owner of my house (and my employer at one time) was a maintenance electrician at Dodge Main. Because all the assembly line folks wanted to keep the maintenance people happy when he ordered an employee deal vehicle all the various lines went out of their way to make sure his car was better than typical. The engine guys basically built him a balanced and blueprinted engine. The engine was still running strong when the car it was in finally rusted and fell apart.

[@duncandmcgrath6290]

My late neighbor was a Windsor plant machine shop manager ... he told me the same story . All the extra time was put in and it was a Dodge nothing when it rolled out .

[@dynodon100]

I had a 66 Val, Signet with a 272 2bll. and ran 14.63 all day long and drove it to and from the track. This was in the early 1970's.

[@MrTheHillfolk]

So glad I didn't take on what I considered to be my first full rebuild until I worked at an engine shop. Gave the crank polisher guy a pizza to polish the crank. Gave some beers and hot dogs to the cyl head guy. Worked out great, I built it at home but had everything I needed bought in house. That made it a bunch easier. Oh and don't be in a hurry at all. It took me about 2-3 months of 3-5 evenings a week to get it done. Remember this is for fun too, so there's no sense in rushing it.

[@mikescherrer4923]

"Don't Hurry" is the cardinal rule of this stuff.

[@L.A.Concrete]

Tony is being humble! He says he’s not an engine builder but he was building nitro motors in his youth. I think he’s an awesome engine builder and extremely intelligent in terms of engines so we should all listen closely to him.

[@coleacanth8944]

the simplicity of your explanations, straight to it, is like a massage for my brain. this is bliss for the inquisitive mind

[@1notgilty]

Uncle Tony is a wealth of knowledge.

[@carmudgeon7478]

So good and to the point. I would add get to know a machinist well. As an 17 year old I mixed Buick 350 pistons, early 60s forged rods, cast odd-fire crank, high-port heads on a low-port block, 252 intake and more, all on a 231 V6. Then Turboed it. Just so I didn't have to stick a belly button 350 in my Sunbird. All the tediousness was worth it.

[@codyhaviland82]

Stock eliminator and Stock class cars are crazy.. My 72yo freind Steve that was a Nhra tech inspector and licensing official has a buddy in California with a 440 6brl Stock class car, Steve said there is over $20k in that "stock" engine... I was talking to a guy with a 318 2brl 69 Dart that was running 11.0s at Topeka a few years back, it still blows my mind how they get so much out of stock configurations even knowing what they actually go through to do it.. Those people have more time and money in there combination than most do in their full on race engines..

[@Sedan57Chevy]

This is absolutely fascinating. Getting the most out of what youhave, instead of just buying something shiny and new, is a real art form.

[@tomfewins5803]

Funny I liked your post and then saw we have matching cars, my '57 is wanting a rebuild, just bought it and spending money already , oil plugs filters the usual , then I see there's just water in radiator, and she's over heating. Some previous owners never care for the rights parts of a car. How's yours doing?

[@slickline4576]

While working in the DIRECT CONECTION END of dealerships near Pittsburgh pa had a street stock team come to several dealers measured 81 rod piston assembly sets to get 8 this team was sponsored by Broadway Dodge in Mc keys rocks just out side of Pittsburgh. I will never forget that... I was Amazed....

[@paulpepi1047]

Said it once and I'll say it again , I learn something new every time I watch tony explained things , bloody good teacher .

[@spankyham9607]

This is great information I wish I knew years ago. No one ever explains this stuff. I never knew there was so much slop in these engines and maybe that is why the newer engines are better with computer cnc and modern castings.

[@nathanmortenson914]

In theory yes,but those CNC machines can have just as much slop in a production run from the beginning to the end. Just consider the wear on the cutting tools by the end the run. Not cutting as deep or boring the same as the beginning. Or that the 12yo operator in China trusting the machine to do it right. We're someone doing by hand with their micrometer. It can go either way.

[@douglashewitt5064]

I paid to have my delivery truck 460 balanced and blue printed 27 years ago. I don't believe they took the time to compare all the parts like you explained. They balanced the parts, but the blue printing like this would be too expensive. Wow.

[@timothyarnott3584]

Hey Tony, Tim here, i love the "stock Eliminator" reference used, as those guys go thru HOURS of painstaking time to create a good motor, ex: my stock eliminator buddy set a new record in 1987.....and they had to retire the time slip, cuz nobody cud get there, and beat it!! one of the things he and his partner did, was go thru 120 Rockers, to find 16 that had the max ratio allowed, also off-set ground the crank for max tolerance of stroke......those are the time consuming, painstaking things an engine builder for SE has/shud do......btw it was a '69 BB Camaro.......when they broke the record, NHRA, has to tear it down to chk.....understandably, but the idiot measuring the stroke, measured it on the exhaust side of the piston, and told my guys they were not legal.....my man, argued, and said "WHY ARE YOU MEASURING ON THE SIDE OF THE PISTON?? ARE YOU STUPID??, YOU MEASURE AT THE CENTER OF THE PISTON, AS IT ROCKS IN THE BORE FOR SKIRT CLEARENCE!!!!".......dude took new measurements, and they were PERFECT on the max allowed stroke!!!.....there you have it, a SE story, and an idiot NHRA tech, back in '87.......nice vid, hope u enjoyed the little story!!!.....LOVE UR STUFF my brother!!

[@indianaslim4971]

This is why many people only run a particular engine no matter what body it's going into, building up a hoard of parts so they can mix and match.

[@gadget73]

I did this with the valvetrain on a Ford 302. Moved rockers and pushrods around until it all came out exactly where it needed to be. Some have thin shims, some have thick, some have none, but the lifter preload is dead nuts and the top end is very quiet now.

[@oops1952]

Thanks again Unk. Stock eliminator always inspired me. I always wanted to take a small block dodge using best parts from different years (eg. '72 360 short block, '66 273 D stock dart cam and rockers, '70 340 heads and 6pack, etc). After you blow the doors off of someone you can say the engine is all stock parts....wink wink...nudge nudge.

[@butcher4842]

Don't forget, the crankshaft in a 273 is factory Forged and is the same stroke as a 340 and 318. Good stuff here.

[@oops1952]

@@butcher4842 Good point. I liked the 318-3 truck crank. It was forged with shot peened journals. For the extra cubes I like the 360. The '71/'72 had flat top pistons. The HP '74 had a cast crank with shot peened journals good for 6500 rpm. It also had a windage tray and double roller chain.

[@davidedgar2818]

I'd call it about 100 hours for a serious build. We used 1 machine shop for all the precision work, but we would go over to help and learn. Pay your money and your dues to a reliable machine shop. This always pays off, you have to realize your capabilities. Just because you can assemble a working engine doesn't mean it's going to be good or long lasting.

I love the comment at the end "I'm a careful assembler." I strive to be that as well. Just recently put my aircooled vw engine together, and realized how much time could've been spent blueprinting that. Like you said though, I'm not an expert, I just measured bearing and stuff. Made sure it was all as clean as I can make it. Hope it lasts at least 50k lol

[@modelnutty6503]

[@thewholls7176]

Yes I’ve seen a 253 holden V8 that when mocked up….. Two lifters were not spinning in the bore and that was believed to be due to an anomaly with the casting of the block itself…… the angles were not quite right on that particular casting…. To correct that they used shims…… OR you could go to solid roller lifters….. Point being is blueprinting should detect and correct these things………

[@2HacksGarage]

Great video Tony!! I am currently building a stroker engine with a lot of aftermarket parts and I have found measuring every little detail is key.

[@trxtech3010]

You have to remember your Rod Bearing wear will cause the piston to sit lower then normal! Upper rod bearing will wear faster then the bottom one in a high mileage engine which will make the piston dit lower by 3 or 4 or more thousandths of an inch.

Working on a assembly line in a plastic pipe factory,maybe 2-3 days out of the year the pipe would come out at spec of the ambient temperature of 75 degrees. The rest of the year we'd either have to shrink a sample in the summer or warm it up in the winter to 75. To make the adjustments to allow for shrink. These adjustments would change for day and night. (If the line operator is paying attention) Could only imagine the variations of castings over the course of a decade.

[@timothybyrom5560]

Measure center to center on the rods. Match them to the pistons.

I bushing rods all the time to correct rod lengths. Plus the rods and minus the pistons and hopefully you can get everything to be the same height. Then you got to have the crank ground exactly right or it starts getting off again.

I went to buy a used 454 bare block for a project. I had a 366 tall deck bbc which has a 427 bbc stroke crank/rotating assembly and its forged/nitrided from the factory ( for dump truck use). I was going to use my existing dumptruck crank in the 454 block with some new pistons etc to make a 427bbc. The guy selling the 454 block also had a freshly machined 1968 396 bbc Shortblock unassembled with all the bearings and pistons in boxes (new) (20 years ago the machining was done) It was stored properly and good as new. I bought the 396 shortblock instead of the 454 block and assembled it myself with a roller cam etc. The piston rings were already on the pistons and gapped etc. ( i checked anyway. I took my time as it was my first time putting a bottom end together. I checked ALL clearances. I used the low compression large oval port small valve BBC dumptruck heads on it and put it in a 58 Bel AIr. Lets just say the low end torque from the small valves is real nice. I used a 700r4 trans to give me overdrive. I need to up the rear gear now from 3.38 factory to a 373 or 390. I sold off the 366 tall deck and its crank/rods. it was 1100$ for the machined ready to assemble 396 shortblock assembly vs. $500 for a bare block that needed everything. Easy choice.

Good vid UT. There's so much detail in building a hot engine it's not funny. I love the fact you break down the basics so everyone can start to get a grasp on how it works, and maybe even show a bit of respect when they bump into someone that does build them. Thanks for the upload!

[@Tommy_Mac]

Leave it to UT to get it right! I always thought calling it "blueprinting" wasn't an adequate term. I knew several racers that ran cars in stock and super stock in the mid to late '70s. I saw some of the work they went through (only as a helper). It's difficult to describe their dedication and skills. Assembling and balancing everything "tighter than a gnat's ass" is amazingly tedious. You really need to 'embrace the suck' to get positive results. I never saw a blueprint or dimensional drawing for an engine. It was usually well-worn pages of clearance and tolerance charts from a service manual. I feel 'optimizing' is a much better description. Much respect to those 'optimizing' out there in YT land! Embrace the suck'!

[@andrewwade5604]

(Backyard) built a 360 25 years ago. CC'd everything. Worst case I could put together was 10.78 ~ 11.2 CR (.34 CR). Swapped heads side to side and a couple of pistons (domed so less positions they can go Vs flat tops), got it to 10.76 ~ 11.00 (.23CR) Every little bit helps.

I paint the head surface, put them on the empty block. Then scrib a circle on the head face. That leaves you a perfect mark to unshroud the head. You will be surprised how much head you can remove, I think you know that. Good job.

[@hoonaticbloggs5402]

The rolls Royce merlin engines were all blueprinted when assembled in the U.K. factories.

Great stuff as usual. I do wonder how easily Uncle turns those blocks on the engine stands. When I've done that the dang thing binds and makes for a battle royale.

I don't know if you can see the pistons difference in person or if the camera picks up more stuff,but the first ones you showed have bump outs on them.the one in your right hand has one near the middle and the other has it near the bottom. I know sometimes the camera picks up more information at times. Maybe where the push rod kept pushing up and wearing over the years. My buddy/mentor Bob is one of the incredible engine pro builders you speak of, he's flat out amazing! From full on race engines to daily drivers, what's even funnier, and not ha ha funny,but peculiar,is he doesn't read that well.

Be doing something similar on a 68 318.

Taller pistons make sense and there is a chart that shows it online. I'm going to use 315 closed chambers to replace the engines stock 675s. Of course the stock pistons could be shot anyway. 🙄

I want to rebuilt my 73 VW Beetle motor and might as well blueprint it. I believe you have to get each and every set of components to weigh exactly the same. So take the weight of your lightest piston and remove where you can do so safely from the rest until all 4 weigh the same. And so forth for everything. Sounds like a lot of work but might be worth it?

When I go to rebuilt modify my LA 360 I'm going to check this stuff out especially with my buddy at his machine shop in Harrison ark = Premier machine shop Rick Cross . to save money I will be buying a 60.00 digital scale from the kitchen supply section at walmart super center to weight my pistions and rods but will have to drop my crank off at the machine shop to have it checked for balancing 😎🔧💪🏁
