Carnage - Drag Challenge Ute Part-14 - Dialling In The Cam

It's a short week for us in the Carnage Workshop as we prepare for multiple events. But parts keep arriving for the Ute so we decided to show you the process of dialling in the Crow Cam.
Street Machine Carnage is all about having fun with cars. Sometimes it's serious performance, sometimes it's crazy fun, but it always interesting and done on a budget.

No one watched the plumbing/wiring video? I did! Great seeing all the stages of the Ute build Scotty!

[@STREETMACHINETV]

Unfortunately, they didn't do as well as previous episodes

[@adammiller4533]

I loved it and love learning. Keep it up

[@someyoungguy6990]

@@STREETMACHINETV Kinda shit when it's all part of a build. It's like saying bugger the pain and wheels, seen it all before.

[@STREETMACHINETV]

@@someyoungguy6990 yep, it's disappointing

[@castekracing]

Hearing Scotty say he's gonna go grab his shaft at 7 in the morning on a Friday just sets me up for an awesome weekend ahead 😂

[@mattcapa2204]

I watch all your videos regardless…. Wiring is still a part of the process and in my opinion one of the most important factors in a proper build! Keep at it ❤

[@FuManchu5ltr]

If it’s any consolation, I loved watching the wiring videos.

[@LRogan520]

Now thats great to watch cam degree, etc, as you said, time-consuming but too me interesting .

[@watchthisspacecarchannel6523]

I loved doing all the boring stuff when I built my 440 for the 69 Dodge charger I had in the 90's , it's just that little bit more insurance when you go all out on a build, great video Scotty

[@Beer_Dad1975]

As Bob Ross would say, that cam is wet & slick and ready to go!

[@FuManchu5ltr]

Did we just see the Bob Ross of the Street Machine world start to make a happy little engine? I think we did.

[@dangdang3970]

Not sure why no one watched the wiring vid, i did and i have no intrest in ever wiring my haltech into commodore myself... i guess some people missed the point of this build witch, to quot ep1 was " we will show everhthing involved in a build to this calibre" or words to that effect. Keep it up guys 🤘🤠👍

[@garrymcgaw4745]

DAMN!, you sure are patient mate, and time consuming for sure. Can't wait to see the finished product. 👍.

[@brad.979.]

I love it when Scotty plays his large bump stick😅

[@seanb250]

Personally I install camshafts 1 degree advanced from your target centreline with a new timing chain, once that chain goes through it’s initial stretch it retards the cam 1 degree in most cases.

[@plumbs7199]

It’s Friday !! Love ya work Scotty ! Not easy to do what you do in front of the whole world !

[@1969Risky]

There will be a ton of Shaft comments here lol. Great video Scotty & this ute will be a beast when it's done!

[@Devastator0]

Love your work as always Scotty!! I'm legit so excited to see how the Ute turns out for you!! Keeping all the fingers and toes crossed that it's gonna be good!

[@colinmiles9390]

Another fantastic show Scotty! That motor is going to be a beast in that Ute. It’s getting close now to completion 👊👍💪👌

[@davenorman8251]

Ex 270 at 50, Int likely to be in the 260's and its a crow so its like a 1254 but on 117 lsa..It's gonna want to run at about 7500rpm ...Mmm Yes Large..I see a lot of exhaust flames in scotty's future.

[@Berg-vm5ht]

@.990 lift on the exhaust 🎉😂😂😂

[@mysticgreg]

I'm LOVING this build! Can't wait to hear this lumpy boi fire up for the first time. Also stoked to hear Dad's Ute is still getting some love - you road-tripping it up there? Hope we get to see at least a little bit of that!

[@STREETMACHINETV]

That's the plan

[@VaughanMunro-js4nr]

Another Great Video keep up the good work.

[@leightonB69]

😮great work Scotty and the carnage crew

[@DodgyBrothersEngineering]

Speak for yourself, I watched it! Would like to have seen a lot more block prep. See several things that have been missed from a engine of this level.

[@TurboHDT]

same

[@azza9575]

You just need to debur and chamfer all the edges

[@DodgyBrothersEngineering]

@@azza9575that's a start, but there is still more things to be done that can have a big impact on performance. First thing I would be doing is knocking the sharp edges off the piston valve reliefs with a sand roll. Boost means increased cylinder pressure and heat. More chance of uncontrolled detonation or having less timing. Second thing I'd be looking at is the rough casting in the engine valley. That slows down oil return. Lots can be done to chamfer holes to allow the oil to return faster, in SBC we would coat the valley in a varnish to make it more slippery. Block some passages off, while opening others up. Other things can be done but they would be the starting point for me.

[@azza9575]

@DodgyBrothersEngineering thiS what I ment ,maybe I should have given a detailed reply, I don't what u mean by sanding the piston valve pockets, the pistons shouldn't have any sharp edges on them , if they did I would be looking at a different brand of pistion, I have all my pistons coated anyway

[@DodgyBrothersEngineering]

​ @azza9575 most pistons have sharp edges on them it is part and parcel of the way they are made, some people just stick them in as purchased, other take the time to prep the pistons properly. The same way some people will buy after market cylinder heads and just stick them on the engine without pulling them apart and making sure that they are properly set up (check spring heights and pressures) and lapped in. This is the difference between someone who slaps an engine together and someone who builds an engine. Any idiot can buy a catalog of parts and slap them together, the smart guys put the extra effort in to make sure every part is working at its optimum. When pistons are made they are made to a pre-finished state, the valve reliefs are cut after the piston has been formed with a fly cutter to ensure finish and depth of cut are accurate. Take a look at the video, or any photo of a piston that has valve reliefs and you will see a sharp edge where the fly cutter cuts into the piston. Now... What do we know about aluminium? It is an excellent conductor of heat, that is why heat sinks are made out of it. So imagine you have an extreme heat source (combustion) and you have a small knife like edge, guess which part of that piston mass is going to start glowing first. It's not going to be the solid flat mass, it is the sharp edge that is going to be the hottest spot on the piston. Now what we used to do on blown race engines (and I did it on my own N/A engines) was take a die grinder with a very fine sanding roll and blend / roll that 90 degree edge where the fly cutter first touches the piston first taking the sharp point off it. You don't need to get crazy just put a small radius on it so it no longer has a sharp corner on it. Of course you do this prior to any balancing. Not that you would change much as you are doing the same to all the pistons, so the changes should be uniform if you have done it right. But you have just removed the potential hot spot from a high compression engine. Have you ever owned a petrol car that dieseled on? That is because something within the combustion chamber (usually carbon) was hot enough to ignite the fuel even after the car had been turned off. Now add a butt load more pressure / heat in the form of boost and you have the recipe for a problem. When a tuner is tuning the car they might back the timing off because they are detecting knock, this can be attributed to uncontrolled combustion, and guess what causes that... The valley isn't the only place that appreciates a bit of love, the bottom end does as well. Another way to loose HP is to to have oil dripping back over spinning parts like the cam and the crank. So where possible through some careful manipulation you can block and guide oil to where you want it. You have to remember that engines for the most part are not built to extract every single HP out of them, so to get those extra few HP you need to look for ways to improve the basic engine. In some cases you are just building in protection. Show me a single engine that would prefer to have excess oil stuck in the heads and not in the oil pan. The bolt on crowd will fit a high volume oil pump and not give a second thought to getting that oil back into the oil pan. Then they wonder why all these expensive parts they bought just failed because they spun a bearing because of lack of oil pressure, because there was no oil. They haven't given a single thought to increasing the oil capacity of the oil pan. They are sucking it up at a greater rate but have given no thought to the oil supply in the pan, and then wonder why their oil pressure is crap at revs. They rev the engine harder and give no thought to trying to stop the oil from frothing and sucking up air causing lack of proper oil supply. These are things you can't buy, these are things that have to be addressed with intelligence. Many decades ago when I was a young fella it wasn't uncommon to run external oil lines on inline six cylinder engine to make sure that number 1 and 6 were getting enough oil at high revs. Fine while running it as a stock engine, but a point of failure once it is pushed to its limits. No block prep shows either a lack of true understanding of a performance engine, or someone that is just plain lazy.

[@dirtymuleracing5321]

Love these videos

[@robvegas9354]

Great video Scotty. I dig seeing all of the details that go into the engine build! Looking forward to the next video! Stay cool this weekend mate, scorcher here in Melbourne.

[@jc9474]

I guess the big dollar builds get the views and whatnot, but sometimes I'd just like to watch ol Scotty hack and slash his way into the 12's for $1200. Make budget thrashing great again.

[@heyshorrtty7001]

That’s awesome news Scotty. Will see you there at COTM

[@johnkirkilis34]

Nice piece of expensive jewellery ❤.

[@kenny1034]

When you were lubing up that shaft you could see how big it is!

[@zeroyon9]

Nothing wrong with a wiring video, just they are all haltech ! Appreciate the sponsorship issue but be nice to see a vid on fueltech, motec, link, emtron etc its a big interesting market

[@STREETMACHINETV]

The trouble with that is none of those companies support us. We looked into Fueltech and they wanted us to buy the ECU, whereas Haltech has been a great supporter

[@zeroyon9]

@@STREETMACHINETV figured. Well let's make this channel so popular they are all sending you ECUs to promo.

[@Doc_in_the_carpet_truck]

So want a lumpy cam in the L98 goodness!!!

[@ryano0587]

Also how lumpy a cam is comes from the lobe separation the lower the lumpyer duration has to do with torque and how the engine breathes

[@ryano0587]

I watched it all and didn’t even vote to see it maybe you should shout out the people that did watch it if it was no one 😢

[@STREETMACHINETV]

Always grateful for those that tune in, just frustrated

[@dianawoods6985]

Question, Did the block come with the cam bearings already pressed in? I find using the water pump bolts screwed into the end of the cam really helps guide it into place.

[@warrenscarlett9302]

👍👍👍

[@user-mn3qf6hy4w]

Imagine you supercharge the 427 engine with the twin turbos.

[@jimclarke1108]

Nothin wrong with a lumpy cam in a 7.0 litre LS✌

[@deancunningham4539]

Slide it in carefully- - - - thats what she said!!!! 😅😅😅

[@naiahhaian]

My advertised cam duration specs are what yours are at .050" 😅

[@STREETMACHINETV]

It's the biggest cam I've ever fitted to an engine, that's for sure.

[@stevenkirk2563]

It’s a fkn monster. The valve hang will make it rev like a 2 stroke:-)

[@michaelteasdale2919]

As long as I live I’ll never understand cam specs…. All the duration and separation and what not It’s all Greek to me!?!

[@robberry1949]

Interested to know lobe separation angle, l hear it makes big differences in LS with boost. Nice install and well taught Scotty.

[@STREETMACHINETV]

117

[@seanb250]

So exhaust centreline is 119 👍

[@badstimpy]

Did you pop loctite or thread sealant in those plugs behind the cam gear ? Don’t want them coming loose and munching the timing gear / chain 😮

[@STREETMACHINETV]

They're O-ring fittings, they won't leak. And I don't believe they'll come loose

[@lukeclarke1068]

How’s the Covid wagon going?

[@dirtymuleracing5321]

Chet Herbert use to say, big or f*cking bigger regarding cams. I watched the wiring videos……

[@danielmcgregor8528]

Scotty, obviously a boost friendly cam with less intake than exhaust lift, I can understand that. Can I ask though what sort of rev range you are expecting?

[@STREETMACHINETV]

With the longer stroke of the 427, I suspect we'll be around the 6500 to 7000rpm area, but ultimately we'll see when it hits the dyno.

[@vintagetractorsaustralia]

Just waiting for the chorus of people complaining about the extension on the torque wrench. Lol.

this series gonna be 100 parts long atleast

Listening to this while working then the music went 80s porn went round to see screen and Scotty is knuckle deep 😅

Roller cam or roller lifters?

[@STREETMACHINETV]

Both. Roller cam profiles are necessary for roller lifters

😜👍🇦🇺

[@TurboHDT]

270@0.50 did you get a custom grind? biggest off the shelf Crow is@0.50 is 245/262 .614/.614 114, 242/262 .610/.616 116 big isn't always better think I would have gone solid over that, Big springs, rockers, and retainers, there is something like 15 to 25 HP with roller rockers over the stock rockers you got a hyd cam that big but took out compression using a dish piston, I'm wondering how thats going to work with spool and launch RPM, will be interesting how it goes for sure a couple of things that, some people think drag race engines in 2 camps, 1 camp is guys who build super street/sedan group3 racing and those who build super stock group2 all in engines, I'm in the latter group, don't take this the wrong way Scotty as I'm so into your build, you got some great parts but your building in compermise you can only count on 1 hand the engine guys in OZ who can build group 2 engines that break national records so I'm a little disappointed and you have a very nice o-ring block can I ask who came up with your engine combo?

How much boost are you boys planning on running in the Ute?

[@STREETMACHINETV]

low 30s

[@stevenkirk2563]

You don’t need to degree a cam if ur deck height is unchanged or your piston crown is the same as a stock piston. It is good to just check it. If you are super keep Dyno the engine and retard the cam til it stops making power. That’s how club racing dudes do it.

270 deg, that's not a cam it's a Chop stick. With all that boost it's gonna suck low flying birds out of the sky!

[@DodgyBrothersEngineering]

NOOOOOOO!!!! lube on the lifters before you have dialed it in. You only have the spring in the dial indicator to resist that extra lumpy uneven thickness. Scotty what were you thinking... Plain light oil, stop using lube on everything and use plain engine oil for test fitting. You should have washed the cam properly in petrol to remove the protective coating then given it a light coat of oil. You're not spinning it at revs, oil is more than enough for testing.

[@STREETMACHINETV]

It was light enough
