What a great vid guys, I have a real soft spot for the old Aussie designed and built engines, and as I’ve heard once or twice before, ‘there nothin’ like the sound of a v8’
@@AndrewMitchell001 It has to do with head design, too. Siamese port 18 degree SB Chev's sound better than Holden V8's IMO due to the heads and firing order. But I think we can all universally agree that LS Chevs are one of the worst sounding V8's in existence LOL.
No where close to this budget, but I helped a mate with the cam, heads and intake for his 308 project. I fitted LS6 springs, small retainers and +0.050 locks with no machining to 5.0i VN ported heads with standard valves. It flowed 230cfm@0.5in lift, and with the ported Edelbrock AirGap manifold flowed between 200-210cfm per port. Rest was standard fair, only 0.060in over Mace flat tops and a 290 advertised duration cam, 232@0.050 with 110LSA and 0.49in lift. While in the running in and basic tuneup, the thing pulls clean in 4th (of a 5 speed Supra box), 1500rpm at 50km/h. Climbs hills no trouble at that speed either. Performance is linear, no fall off in push. I was brave enough to take it to 7500 and it did it effortlessly. Admittedly, it's in a light VC Commodore. No benchmark performance numbers as of yet. All said and done, it only cost me $1100nz for the springs, retainers, locks and manifold. If you want to copy, watch your cam lift to prevent coil bind. The sub 0.5in lift helped me in this area. Sounds great too, doesn't go into higher pitch 308 "clap" above 4000. Just a nice, polished bellow.
Just an update. It ran an even 300hp@6000 on a hub dyno. The operator didn't want to take it higher however the power hadn't nosed over. Torque peaked at 4500. Compared to an early head 308, this one was up 50nm on peak, and 56hp. In fact, nowhere in the rpm did the smaller head win out. Even as low as 2000rpm was in favor of the injected head. What was different was the peaks were some 750rpm later for torque (4500 over 3750) and top end was 500rpm+ (5500 over 6000). The injected heads haven't given up at 6000 either, but power was no longer climbing. Considering the stock bottom end, it's best for the owner to stay on the underside of 7000, otherwise it won't last...
Sounds nuts! Can’t wait to hear this thing hit Lygon on a Saturday night! I’ll keep an ear out for it whilst i smash my souva from Lambs :) Nice feature boys!
The biggest secret to engine builds is engine science and what is the best for reliability and also performance balanced, so the right products and the right tech in every aspect and bang for bucks you can get it right and when its right, wow 700HP at the crank all day long day in and day out. well done to all the team members and i hope more engines are shown on the channel, plus with out engine builders expert knowledge, as they say experience is the best teacher, not like some engine builders who will sell you the best parts but have no idea of how to put all the science together like LSA lobe angles based on air flow rates etc? Keep up the great work guys cant ait till more uploads are on.👍👍😎😎✔✔
With a combo like this (or even any well built Holden stroker) the block becomes the weakest part of the engine. Which isn't ideal, but beggars can't be choosers. Martin, you're welcome to build one to turn to 9,500 - 10,000. They most certainly CAN NOT handle that.
That thing will sound mint getting down the road! 👍 Nice street motor, it'll be enough for pretty much anything that pulls up at the traffic light drags... 😂
12.8 is far from massive and compression means nothing when you have an efficient cylinder head. The camshaft is far from in the 280’s and anyone mechanically mined would know that in the 280’s is on the larger size that this combination does not require.
@@domdagostino8833 From most hot/wild engines I have seen 11.5 was about as high as I saw on 98 due to being detonation limited but of course if you have a big enough cam the dynamic comp drops enough to warrant a high static comp in order to compensate. In my mate's speedway V6 that I designed and consulted for him, we ran 14.5:1, not that the cam was big but that the rules allowed the use of E85, paired with a medium cam the result was a very fat mid range torque curve, it was only possible due to not being det limited on the fuel and could achieve MBT throughout. If it was still on 98 then 10.5 to 11 would of been about the max before det would limit achieving MBT.
@@domdagostino8833 Correct. Jesus christ, 900hp NASCAR 5.7's are barely 280 duration at 50. Do you know how massive a cam that is vnv8dude? That would be advertised duration of 319 degrees for chrissake. The overlap with a decent LSA would be near 70 degrees. That's drag racing ONLY. Clearly NOT the cam used in the streeter engine he's built, and it sounds nothing like that. It would be a baby, considered. Something like a 255/262 - 260/266 with a 110LSA installed 2 degrees, is what it sounds like. Probably even milder.
It really depends on ones goals, 12.7 on pump fuel is right on the edge for most, to achive that the lsa and lift would of been very custom as a general rule 355 10 to 11 to 1 comp vn rubbed heads a can @050 of 230 by 233 ish at 575 lift at 110 or even 108 lsa whit a sigle planeshould net 400 easily every day very very easily to hit 700 well you can rev the piss out of a 355, but a 383 or larger is the way to go, and much credit to these guys for doing it that way. i wont give away too much info cos we get trashed hard if we give up the so called secrets but just aim fora good runner that will hit 30 degrees on cas and 34 on ally and your already half way there
It's pretty typical. A well built 355 with the lot does 600hp (most 355s are NOT well built, just standard rebuilds with a stroker crank bottom end thrown in, which is why most are well below that). Add more cubes down below and better heads and the extra 100hp is easy peasy. You can tell by the hand-made headers on this thing, that there ain't no junk in it and no expense spared, even though the combo is 'street friendly' or mild.
And barra wanks can say what they want but guarantee you would need a 1200hp barra to 1/4 mile faster than a 700hp Holden...MPH means shit if you lose..
Where does the effective power band start with a tunnel ram like that? The 350 - 383 stroker engines are so old school, I would have never thought I would see one on youtube.. Was the crankshaft ever lightened up to give better throttle response for the 383 build? Beautiful engine but would it all fit under the hood? (0_o)
The biggest part of throttle response is FLYWHEEL lightening, not crankshaft. Most crankshafts have a minimum weight to function properly for balancing.
great build but the headline is a bit of a fib. find me some parts on that motor that are actual Holden parts? same as a ford or chev, by the time you put aftermarket rotating assembly and heads and so on and so on there ain't much chev, holden or ford left.
700hp from a 308? thats 140hp per litre. thats what the latest nascar engines put out per litre!! really? without injection and still 2 valve head and on 98 octane? i find that almost impossible to believe, but may be true..the latest Ferraris DO NOT put out 140 hp per litre, stock!!

What a great vid guys, I have a real soft spot for the old Aussie designed and built engines, and as I’ve heard once or twice before, ‘there nothin’ like the sound of a v8’
can we all agree that the Holden v8 sounds better than any Ls? not a 308/304 with no muffler making a massive 250hp
I've heard a few nice sounding 308 high compression engines.
High revving Holden Stroker sounds so much better than an LS unless it's one of those hypo LS engines turning to 9000+
Cause 9 out of 10 Ls going around run hydro cams with wide lsa
Of course they do if the LS had the same firing order they would sound the same too.
@@AndrewMitchell001 It has to do with head design, too. Siamese port 18 degree SB Chev's sound better than Holden V8's IMO due to the heads and firing order. But I think we can all universally agree that LS Chevs are one of the worst sounding V8's in existence LOL.
That looks like it could keep revving well past 8000rpm and making more power up there. 👍 Just awesome. 😎
It's always good to see people still playing with the old Holden engines👌

Yup for sure bro good motors👍🏾
@@YKATO871 can't wait to mine bolted up back in my torana.
Yea i bet, i know the agony of waiting😂
You are right there, just not the same! Best sounding engine a s well👍🏾
Great build . A tough Holden V8 does sound bloody nice .
With those hand-made headers absolutely! No off the shelf junk.
I can’t love this video enough! Bloody Aussie power 💪

R.I.P Holden. 😕

" listen to the motor.. " How true !
Aha this is so cool
NEATO HOLDEN power. Have a safe and nice day all. CHEERS from AUSTRALIA.
Beautiful craftsmanship gentlemen!
Beautiful old skool sound
Nice Tri-Y Style Headers
Two carb set up with a natural type. rules !
I can't believe that you were able to get any parts out of torque power 😳🤣. That truly is a miracle. 👍
7:00 ...awe ..lol
True though, great guys great commentary where the builder is happy to give credit where its due.
my dads famous
So's ya mum 😉
That thing sounds great!!
Loving the content boys keep it up 👍
I'm amazed the block can cope.
Guess being iron it should be pretty stout.
Not at all amazed, they can handle 9500 RPM all day and break eventually at 10000 RPM

I love seeing workshop tours and was expecting one t the end but nonetheless another good video on someones work and good blokes too
Keep up the great work 👍 👏

Needs 700hp to lygon street on a Saturday night 🤣🤣🤣😁
Correct as he likes to get there faster than what he would if it only had 650hp…..
Yeah in late 80s
Would rather this in my HQ over an ls ANY DAY
That's impressive, N/A & not far of 700hp on '98, great stuff. Just a shame it won't fit under many bonnets.
That's a decent amount of compression. Wonder what the cam specs are like?
would be in the 280s@50 or there abouts

Peter Michael's made more than that 20 years ago with a 355 flat tappet with -3 yt heads ran 8,89
This is fckin awesome 🤩
Mate...if it can rev and not blow up the first time.... that's good enough for me
So when Pete's not playing with his guitar he's playing with a die grinder.
He's seen better days...
It really depends on ones goals, 12.7 on pump fuel is right on the edge for most, to achive that the lsa and lift would of been very custom
as a general rule
355
10 to 11 to 1 comp
vn rubbed heads
a can @050 of 230 by 233 ish at 575 lift at 110 or even 108 lsa
whit a sigle planeshould net 400 easily every day very very easily
to hit 700
well you can rev the piss out of a 355, but a 383 or larger is the way to go, and much credit to these guys for doing it that way. i wont give away too much info cos we get trashed hard if we give up the so called secrets

Did anyone else notice the throttle cable coming loose at 1:00?!
Brah why would ya want this when could get a 2k barra lol jokes boys jokes lol always great content keep it up
Because every wanker has a Barra or a ls and it's good to be different
And barra wanks can say what they want but guarantee you would need a 1200hp barra to 1/4 mile faster than a 700hp Holden...MPH means shit if you lose..
And a wash

2k holdon
Did I miss the part where they mentioned what is was going in?
It's going into a Holden 👍
What car is it going in
Specs on camshaft
Geez, my stock VS threw a rod at 6500 😆
🏎🤘
Tuff
What would a build like this cost?
30k
Or the ultimate....as it rev's. It gets faster.... infinite
Everything sound good till you get the price
As a American........that looks like a Ford.
The dizzys at the rear tho mate
The old 308 was an invitation for Uncle Rodney to come out. The later one's were much better.
great build but the headline is a bit of a fib. find me some parts on that motor that are actual Holden parts? same as a ford or chev, by the time you put aftermarket rotating assembly and heads and so on and so on there ain't much chev, holden or ford left.
You do make a good point there. I have a stroked SBC & not one part is from GM.
Cheers & stay safe😊
What would you prefer us to call it?
Well the main part is, Holden Block from the Holden Factory? Even they used Harrop for their 355 Cranks so not sure what your point is…..
@@fullboost call it custom engine build then this Will bloke will tell you it is a Holden engine.
The first
Not your average 308
Crap I'm 305 to like
Ha it's still got nothing on a two grand Barra!
Meh 1.25 foot pounds per cube is not something to brag about.
If you want you could donate this to me 🙏
Torque peak at 6800rpm- that’s what you call a street motor ?
What's wrong with the torque spread? This will be a very quick street car.
Peak torque at 6.8k is more streetable in my opinion. Especially NA so very linear
Doesn't matter where the peak is, the shape of the curve is what will change how it drives.
@@greasemonkeychris4128 is that so
The Lobe Separation of the camshaft is what will make it streetable and how the torque curve ramps and comes on. Nothing at all wrong with 6800 peak.
