I love how they designed the car so that you could drop the pan so easily. Great vid...learned a lot from this one.

Not boring at all. Very informative! Get as technical as you can; I can handle the truth.

I like the tech stuff that you have included in the video. I think its important to know not only what works well, but also why it works well with certain setups. In addition to this, especially with mechanical projects, some tech and skills can be applied to a variety of different applications and give rise to new ideas for other applications. Thanks for sharing!

You are right on the harmonic vibrations unscrewing things. I had a high revving 302 that would always back out most bolts on the block. Oil pan, headers, valve covers, water pump and a few other attached items. It was no real problem for me since I often check and re-tighten all the hardware very often. The oil pump was custom as well. The tech talk is good. Many new people get cost saving tips. I been at this for decades. A person can easy write a few thick books just on tips and tricks. Thanks for posting!

Great video, I'm a drag racer so I appreciate everything you had to say and could not agree more. Keep them coming.

Great tech Sir. More videos of your build the more we all learn. And it's great to see what to expect on building a high rpm motor.

Im just an old gearhead whos been mechanicing and dragracing for 30 years or so and i find your vids very informative ,even old turds like me can pick up a tip or two .keep up the good work ,I wish we had u tube when I was starting out ...thanksfor doing this

My interests run to motorcycles and smaller motors, but I I really like the easy way you explain, particularly the simple demos. Rock on!

Just found your channel. Been digging the tech vids. I'll have to check out more! Thanks for all you do for us!

Loved the video. The more tech the better. Even though I build my own engines I don't have the miles down the drags as you do. I also like your stories. We don't have too many Canadians around here so when you say aboot and arouund we get that extra bit of entertainment!

Thanks for sharing your valuable knowledge and experience. I am building a BBC currently and agonizing about the oil system having found solutions from posts like this!

good idea welding bolt heads.....but...me being an aviation mechanic would like to offer you a tip. CHANGE YOUR BOLTS TO AVIATION GRADE, THEY COME DRILLED ACROSS THE HEADS SO YOU CAN SAFETY WIRE THEM IN TANDEM MODE TO EACH OTHER. Its a technique worth learning and applied can be a very safe and eye apealing too. look into this humble tip and hope it helps!

I'd love to see more of the tech stuff. Videos showing little tips like this oil pump video and the video showing how and why you ground part of the block near the cylinder, are golden. These are the things we cant read in the hp books filled with theory. Keep up the great work and I look forward to more tech videos.

Very nice video. To the point and with great illustration! Love it.

I listen intently. Keep the uploads coming!

Great vid! I saw your Road runner Vid too! You build some beasts! The tech stuff is perfect. You explain "why" things happen, not just "oh, that happens and you do this". Keep up the great work!

Love the tec stuff! I Learn so much watchin your videos.. thank you. Keep up the good work. And have a happy new year from indiana :)

Thank you for your informative information! Great looking new pump too!

Your tech videos are awesomee, keeps me learning, thank you very much for posting these!!

very informative video. I have never known that oil pumps are that weak at high rpms. I always thought they live longer than the bearings. thanks a lot

love the tech tipe...have been working in an engine shop in ottawa for 7 year and we weld in every pickup and i have not had on come out yet but in the same note the big buck engine we do use the same style oil pump you installed.... keep up the good videos

This is the kind of stuff we like to see. Keep up the good work. Thank you.

I love the tech stuff! It is the main reason why I subbed to your channel. Do some bike tech videos too like polishing your frame, rebuilds, and replacing seals, or changing fork oil. My dad isn't really into high RPM performance motors and I am, and a lot of the information I get is from channels like you.

like the idea of a one piece unit! Please keep the tech stuff coming. Helps out all of us trying to learn more about the mechanics that go into a working motor high performance or stock.

Being a fellow motorhead I to noticed harmonics is often times overlooked and yes RPMs are the monster in waiting but with cost often times the key factor in our builds the OUTRAGEOUS cost of a Billet pump can sometimes be the Slammed door on the purchase so we keep our fingers crossed and when nobodys looking get down on our knees and say a quick prayer that our motors don't fail I bet your pump was no cheap fix for peace of mind ? GREAT Video !!!!!

Tech stuff is great. Any videos of the CR500 are also great - tech or just humorous. Thanks for the upload!

Old video, but always great to have tech videos. Thanks!

@Luminaring I think once the harmonics start to play a role in the engine the pickup that is extended away from the ridged pump acts kind of like a ruler getting flicked over the side of a table, bring the ruler all the way onto the table, no more buzz.

the tech stuff is really interesting and i learn alot from it too. your really easy to understand and explain it super well.

that was great man super informative, i really don't know anything about cars but i was able to follow and understand what you were talking about.. great idea on your old pump tying the bolts together than putting another piece underneath than welding it all together....i have no problems watching more

You're welcome anytime, Im starting to have an interest in drag racing, I just went to and watched Drag Racing for the first time at Maple Grove Raceway here in Pennsylvania in July. I loved it, awesome power and sound in alot of those cars and trucks. I dont have a drag car but I have a lifted 75 Chevrolet truck I use for shows and cruises with a big block chevy 454, I can use alot of helpful tips from your videos.

My thoughts: post any high performance automotive/mechanical stuff you want, just remember to include a little bit of that off-the-wall sense of humor! Your vids make me happy - that's why I keep coming back. Love your stuff.

I like your videos, very educational. I learned alot of things I never knew before.

found this! wish you would talk more about your passion like this

Great to see your tech stuff....but also great to see those big out doors stuff, the flooding of the river, or the draining of your back yard when the snows melting. Part of the college education in mech eng involved the ideas & some calculations about the harmonic points in shafts, and often it was possible to chase the harmonic point beyond the normal rev range, by size of shafts & position of bearings. But if you start to hunt more power, you start to push holes in the envelope.

Tech Vids are always good to share and discuss. I would like to mention contributing factors to welded pickups not staying put. As you stated always consider the harmonics of the engine and RPM is a large part of that. But consider when these are put in 3000+ lb cars on factory engine mounts all with some sort of vibration dampening it is way more cushy of a ride. Now to me the major difference is in a tube chassis car with solid motor plates and about 3 1/2 " of suspension. Now combine that chassis car with a hint of tire shake or even just a chatter and hello cracks. Im not saying your wrong in RPM and harmonics being a large part but in my 30+ years racing the big heavy cars as stated above even with killer high rpm motors I have seen the welded pumps work for years. But I also noticed a difference when guys started stepping up to chassis cars altered's and dragsters. Some did have failures who knows why for sure it all could have been coincidence. But I guess we would all have dry sump if we could afford it HaHa

Drag racing a tech stuff go hand in hand. Keep up the great videos. You just gained a subscriber 👌🏻

tech is great food for our brains, i race a rotary but its all related when it comes down to nuts an bolts . its good stuff mate

I like the tech stuff! You know so many things and I really like learning about mechanical stuff.

I just found this, groutaone, been watching mainly the videos on the buggy..I really like it a lot..Very useful information..I got a dune buggy,& also been around racing my whole life.Dirt track mostly,but a lot of drag racing to,,keep em coming,,much to learn & not forget,lol,(love tec stuff)!!

we like the tech talk. iknew about this but it is still good for the younger guys thanks. i see 4.80 on the window,. i have 4.82 on mind.good show

It doesn't matter what you put in a video Groutaone. I'm watching it! I can see where some would be bored by a tech vid, but not me as I almost always learn something from yours, this one too. Just keep doing what you do man! Mix it up and do whatever you're feeling like doing so your heart's in it. Also that way there's a little something for everyone.

loving the tech videos. i think most of your subscribers are into the tech as well as action just like you!

@Motorfordtoyota Thanks, glad you stopped in for a look

@beefystik No, this pump goes in all factory made. Its not so much bolts coming loose but rather that thin pick up extending away from the ridged pump, kind of like when you flick a ruler off the edge of a table and its got that buzz to it.

Great tech tips! Your explanations rock too, thx!

@knikula You bring up a good point, however the neat thing about the new pump is that its aluminum and weighs less than the cast iron one that I took off. Should be ok.

Hey groutaone i really appreciate your tech videos. I'm 22 and am pretty much self taught.. Dirt bikes are my Passion, but I also really enjoy cars. I'm working on a 650hp 408 fox body street car. And I really enjoy the knowledge I gain from your videos.. Its been awhile since my last comment lol. Well time for another one of your tech vids

I like the tech stuff most but enjoy the channel overall and the sense of humor.

Do what you want to do it's your channel and I will watch all of it. Keep the great vids coming.

Great video, very informative. May be you could do complete engine rebuild video/compilation, keep up the good work. We don't get many tech videos over here in the UK for a) drag racing and b) big block Chevy engines.

Hi I'm Sean waltz. I'm 30 years old and race/fabricate race boats.. Its definitely not boring me so please keep up the videos.... And if you can keep my attention your good....

That's Canada. Informative and polite. Very well done!

love that decal at 0:07!

your tech stuff is awesome keep it up I'm learning a lot from u

Nickel is made for welding dissimilar metals.

Awesome tech videos! Keep em comin!!

@binnsh Yep you are right, I think over winter I will modify the pan so its not so deep and make it a little wider for more capacity

I fine the information very helpful. Also you make it very easy to understand . jesse

@P3t3rG1 Its not so much bolts coming loose but rather that thin pick up extending away from the ridged pump, kind of like when you flick a ruler off the edge of a table and its got that buzz to it. Dont seem to have trouble with bolts coming loose at all but I do check the bolts on the new pump that they are tight before I install it

Great video very interesting not boring hear good stuff !!! thanks for sharing...

just keep doing your thing all these vids are top notch!

Naw this is quite interesting I had no idea oil pumps were under that much stress. If I ever upgrade mine ill keep that in mind. Keep up that good work

nice, maybe with the added mass of the new pump design, the oil pump mounting bolts fail instead. Neat looking stuff...the number of revolutions that a drag car engine makes before being rebuilt is surprisingly small. Keep the videos coming, love them.

@g2moto Thanks, seems those always go over well, will make more. its all those other hobbies of mine seem to get in the way.

@Pedro2598 Thanks for watching, glad you keep coming back for more

@pain250x Nice to have some engine guys come around to have a look, thanks for your comment.

@DanielRemains Thanks for the input

i really enjoy the tech stuff, i watch all your videos! I hope to drag race eventually, and i'm learning alot of little tricks from you!

Nice piece of very significant information. Thank You.

@SquirrelFromGradLife It seems the trouble comes from the thin pickup extending away from the pump, it kind of wants to buzz till it breaks off, I checked the fasteners on the new pump, think we are in good shape now.

@beefystik Yes Its a way of tying it all together in the hopes it stays that way

Hey man, thanks for the heads up!

Good Video. I had my milodon pickup break off, even though it was welded and bracketed to the oil pump bolt. I was at the top end of the track and oil pressure went to zero. unfortunately it took out the bearings before I caught it.

@jsnyara A competition engine I will idle it till its warm, then cut the filter open and have a look inside, change the oil and then its ready for hammer down time. A stock engine I just drive it normal and change the oil after twenty minutes or so and just keep driving normal.

ya love the video i had no idea vibrations were so critical. thanks!

@FirebirdFarmboy Thanks for watching, Its not so much bolts coming loose but rather that thin pick up extending away from the ridged pump, kind of like when you flick a ruler off the edge of a table and its got that buzz to it. Dont seem to have trouble with bolts coming loose at all but I do check the bolts on the new pump that they are tight before I install it

love these vids anytime i can learn something is awesome thank you very much

@beeqool Thanks for your input, I really only ride my CR once a month or so, seems there is always something to do around here, even watch tv and lay on the sofa is good too, but more CR vids are sure to come

Good stuff Buddy!! The Tech stuff is great, I'll probably never encounter the problems you do or have any use for any of the info but I still enjoy seeing how things operate and how the problems are solved. But we still need our fix of Goofy Clayton eh!!☺

@RamblinAround Ya this car is fun to work on, and if there is something in the way like the dash or trans tunnel, a few clips and its off, so nice

Thank you You speak in terms I understand and they aer basic and will apply to all motors Thankx agin

keep the tech info coming thanks man.

@groutaone I've been watching your vids on the buggy as well other of your vids. You got really good vids and I can't wait for more.

I had the pick up fall out of a SB Chev. This is good advise.

Nicely explained knowledge. much appreciated time thank u.

Nice pump...peace of mind in that department...I always weld a strap similar to the ones you showed...At 8 grand it's imposable to be quick enough to shut down once you notice there is no oil pressure...BANG!!!!!..Instant crank shaft inspection hole.

@groutaone Sorry I missed you pan question, its a Milodon pan with the windage and kickout

@JccBlazer Thanks for your input, tech vids will show up more and more on my channel, right now I'am occupied with the buggy but would like to do more automotive stuff also

Good video, if you are worried about your bolts coming out from vibration you can drill a hole through the center and wire them together. Then even if one or more loosen up they can't come out. Be a lot easier to get it apart. That new oil pump is a good piece.

@groutaone with mine it was just common deduction that got me there in time. i could run the thing for 30 minutes at highway speeds and it would start tapping and then over heat. I could let it sit for 5-10 minutes and it was good to go another 20 -30 minutes and then the same thing again. wasn't using or losing any coolant. no water or coolant coming out the exhaust so it was either the oil pump, plugged oil passages or worst case a worn out cam. that's the most i have done to that truck too.

@urmomisfineinbed Thanks for watching, if it were possible, I wonder how the oil pump would feel in a persons hand when the engine is full throttle, bet it would hurt just to hold it from the buzz

@groutaone Ya, the one piece pump's integrated pick-up is NO ruler to flop back and forth. And at one pound lighter, it will decrease vibration energy at 8K rpm compared to iron pump vibrating against those mount bolts. So, that pump seems to be the ticket to...no more bad vibs.

Love these tech videos. Plus, their the right length.

Great stuff. Love the tech videos as well.

Thanks for the help and video . love the tech stuff !

awesome!! i always learn alot from ur vids!!

@RicerEater1978 Glad you enjoy my vids, in the end its the details that make a car stand out, its not always who has the most money but the man behind the wrench

Tech vids are a great way for the younger generation like myself to learn from experienced gear heads!

great vid love watching well put together tech stuff on youtube, great to see, will search for any vids you might have on nitrous systems
