$6000 Australian dollars?

Fullboost + Nathan Higgins = Must watch immediately 🤙

Yes, bare.

[@kennethalbert4653]

What compression ratio ? Ball park if secretive please.

[@kevincollins2184]

Dude 6,000$ for a SB2 top end kit is cheap. Around 10-12 years ago just the set of as cast a set of as cast SB2 heads no guides, no seats, literally just out of the molds was over 10,000$

[@ToddWrightthedrummer]

When all that NASCAR take-off stuff was available, heads with Ti valves, T&D or Jesel rockers could be had for

[@StreetLethalRacing]

Expect the pricing to go down even more as the EV's start to take over the roads. Less demand, equals less price, regardless of rarity....

[@idin1976]

Good to see local vendors doing good work and with competitive pricing too!

[@coryholbrook4643]

Good grief 860hp out of a streetable, naturally aspirated small block Chevy package! That’s insane.

Over 640 ftlb speaks of the efficiency

[@AB-80X]

I think the term streetable is up for debate.

[@manitoublack]

Needs IDA webers👌 And a top end pack for $6k aussie for that is awesome

[@MafiaboysWorld]

People are slow today, I expected 20 comments already saying, "wHy bOtHeR, tWo K bArRa iS aLL yOu NeEd!" 😁👍 Love this motor. 850hp, no blower, all grunt. This would go absolutely sick in a sleeper looking VH Commodore. 😎

[@johnwilson1794]

I agree. No 850hp Barra can come close to the sound of an angry N/A V8. Or match it's real world response. Not sure you could put this motor in anything and make it sound like a sleeper though. I'd know immediately not to mess with it just hearing it idle.

[@liamandrewartha4803]

Plenty of steel bumper owners sat up in their seats hearing 850hp street motor on pump fuel with a carby.

[@hendrahendra]

Why bother, two k barra is all you need.

[@hayabusa8184]

Memeulus plenty of na clevors out there over 1000 on pump.

[@BeeskneesBen]

Sounds mint. Carb out the bonnet wouldn't be very 'sleeper' though

[@stuffandjunkandthings364]

I know a couple of drag racing series with a small block no power adder class that these could totally disrupt. Has me re-thinking my current racecar build.

[@homodelrailwaysaustralia6271]

Sounds absolutely stunning guys great work 👌

[@bradyaero]

A thing of beauty!

[@ScooterLee-ei1ep]

SB2 stands for Small Block 2nd Generation. It was designed in the late 80’s through the early 90’s. But wasn’t allowed by nascar until the 2001. (I may be wrong on that one.) you can use these heads on a stock gen one block with milling on the lifter bores.

[@michaelstoker6710]

Just to clarify the sb2 does stand for 2nd generation but its the 2nd generation Nascar engine from GM. Gm also released a generation 2 sbc LT1 in 92 that was reverse flow coolant and a opti spark on the front driven by the cam instead of a crank driven dis. I also think it was 98 that GM switched the the sb2 in nascar.

[@ToddWrightthedrummer]

Fullboost is far more hardcore than any big American KZbin channel. Well done, mates!

[@Motorcitypower1]

I love this , these guys are doing it Right !

[@chrisparry7813]

Lovely good work 💪

[@MmeDesgranges]

Great power and torque from a relatively simple combo. Go the mighty Aussies!

[@danielbrealey2924]

Wow- that's really reasonably priced for what it is!!! Great stuff!!!

[@puttingwarheadsonforeheads9872]

Scott shafiroff sells a 820 hp street motor complete for 20-23k depending on fuel injection system. He also makes a couple that make 900+ with a bit more compression.

[@AB-80X]

He does. The only issue I've seen is that the few I have seen tested, did not quite make the power he claims.

[@cameron6554]

Those rocker covers are beautiful.

[@shitbox7413]

Would be a lot of fun on the street! 🤘

[@scotthultin7769]

Nice 👍

[@eddierotary]

This motor with itb must sound like in heaven.

[@enemymetalworks]

Id love to see a blown alcohol one! I'd happily volunteer my small block fuel altered as test mule lol

[@bdass68ss]

Awesome aussy power at an affordable price..love the concept. .everything is ls anymore

[@7071t6]

WOw great stuff, perfect for anything which has plenty of room under the bonnet, those headers are something else, i have always said that if you have the headers pointing in the same direction as the port and as long as possible before a bend, you will increase HP by at least 10 to 20% easy more on top of your off the shelf headers made by most aftermarket exhaust manufacturers, nothing against them, its just that they have to cater for all those cars which require factory clearances under the bonnet. :) Like Pacemaker, DPE, Hurricane, X force and others?

[@IAW_OPSEC]

Damn that in my s10 blazer sbc would be great .

[@HoonTV]

Jeeezus! Weapon

[@aaronrepairsall]

I'm in love

[@danburke5941]

Awesome to see Aussies kicking arse. Well done Higgins. Got doubt's about the street engine comments though...

[@MrTaylorTexas]

Wow!

[@davy1458]

That the LS killer right there!!!

[@AB-80X]

Don't tell that to the LS fanboys. Then they will say "Just add boost" or some stupid shit like that.

[@steveboros1961]

NEEDS ALL the help it can GET

[@ianmatteson482]

MBE LLC 13* head flows 440 cfm of air. Can make nearly 1000hp naturally aspirated with it

[@fullboost]

Yes but these are in a different price bracket, this particular engine was merely a test mile. 👍

[@vengeanceizmine9878]

Not with a 260-ish cam and a 4150 at that rpm, with that valve size and with that MCSA.. Can't compare apples to oranges, and certainly shouldn't be basing power from a cfm number..

[@ianmatteson482]

VengeanceIzMine agree with everything you say. Didn’t argue that. But a cfm rating is a good number to judge the horsepower that an engine is capable of making with the right combination. Not judging power out of cfm. I’m well aware of the factors that will restrict a head that flows that much if not taken into consideration.

[@SloppyMechanics]

"small block" with a 8x24 valve cover lol

[@enemymetalworks]

I thought you might check this out 😂

[@hayabusa8184]

Moat should do a sloppy sbc build 💯

[@vengeanceizmine9878]

Have to live outside the box when it comes to making real power Normally Aspirated... not as easy as just bolting on 2 hair dryers and letting them do all the work.. lol.

[@AndyGeesGarage]

The bore spacing and block architecture is still small block

What fuel was that on?

[@brightstarlastname2812]

Runs on: Hopes and dreams of small children.

[@markwilson2077]

I need parts for my SB2.2 small block chevy engine that I'm working on.

[@robertacy1785]

How would this package do on a twin turbo setup as far as the two center exhaust ports next to each other?

[@vengeanceizmine9878]

Siamesed center exhaust isn't a huge issue, as turbos have been run successfully for many years on the typical small block Chevrolets, long before any LS came into the picture. More importantly, what I look at, is the very shallow valve angle and very small chamber size this type of head uses. Not saying it can't be done, but they definitely need a different approach to keep pistons in one piece when using Nitrous and Boost.. very timing sensitive, and controlling flame speed is critical.

[@AB-80X]

@@vengeanceizmine9878 The head will be fine on boost or nitrous. What you need is a short stroke that allows for a piston with eh proper crown design, a proper compression height and a strong ring land. Alternatively a tall deck small block would work really well.

[@hondaservicecenter]

Can those guys build me a nasty all motor Honda b series? Seems like everything that comes out of Australia is just mad!!

[@sharons9367]

Let’s see the figures under 6100 rpm !

[@davy1458]

If I had an sb2....I'd have "fuq yer LS" stenciled over top my windshield.

[@AB-80X]

I'd have that no matter what. Now I know what to do for the weekend.

[@leadsled8961]

To think they made that HP with flat tappet cams in NASCAR.

[@therajuncajun6487]

What size carb is on that engine sir?

[@AB-80X]

Looking at the power and seeing that it's 4150, i'd say 950.

[@Circlotron]

At 3:45 he says all the runners point to the centre of the carby so the distance from the valve to the carby is the shortest. Wouldn't it be shorter still (and more equal) if the inlet and exhaust valves on the end cyls were the same position as an OEM head so the pairs of inlet ports were right next to each other instead of being separate by some distance? The new setup does make for a cool looking inlet manifold though.

[@aDaWaN]

I think he most likely meant the straightest rather than the shortest. This head is clearly designed with the single plane carburettor intake in mind. Something like an LS is designed around emissions and injection, so not strange it is less than ideal for a single plane.

[@vengeanceizmine9878]

He is referring to line of site, from valve to plenum... yes, the runner lengths differ from inside to outside, that is a necessary evil on a single carb intake.. this valve arrangement and port layout (often called a mirror port design) allows for a better line of site to the valve, compared to a symmetrical or traditional lay out. Ie: straighter overall intake tract. Hope this helps..

[@grecoconduris6716]

Holly shit.

[@leewilliams8836]

THERE WAS NO FISH IN THE FISH TANK!!

[@davidtolson4804]

LIKE TOO SEE THAT KIT ON A BIG INCH SMALLBLOCK AND SEE WHAT THAT KIT DOES THAN.

[@vengeanceizmine9878]

Apples to apples, same top end and cam on a much bigger cubic inch, will make more power, but at a lower rpm.

[@marcuslimbaugh4592]

Take my money

[@AB-80X]

I'm confused. You say it made 864 by 7500. The dyno show 857 at 7500 and 860.9 at 8000.

[@fullboost]

Yeah that's not the same pull. We did not film every pass the engine made. That is simply the final result.

[@pizzandoughnutspage7817]

That would make my dart 400 sing, were does my money go?

Hey guys freeeeking love all of your videos but what's with the "free lessons" that aren't viewable?

[@MyLonewolf25]

This going to be available in the states?

[@fullboost]

Yes 👍

[@MyLonewolf25]

Fullboost estimated pricing?

[@zkeyes4056]

That oil pressure looks pretty low for the rpm

[@vengeanceizmine9878]

Perfectly normal.. as long as it goes up with rpm, but not too high or power suffers.

[@Hitman-ds1ei]

F**k me, that's the small valve version !! Idles like a Sunday driver
