- This engine was built 7 years and 9000km's ago and I've never checked its output. Old school technology was never going to see huge numbers, but I always thought it was good for 300hp at the crank. I forgot to remove the a/c belt which probably stole a few hp too!
Nice to see a non-LS Holden.
Are you not a fan of GM engines? The LS is the pinnacle of pushrod V8s.
@@blairo15 I think it is the fact that everyone is throwing an LS into old Holden's these days. It gives instant hp but you are losing that old school look, sound and feel. There are days I want to throw an LS into mine but then it will lose a certain charm. It's a hard one to decide on.
there a lot of us out there who love the little Holden v8, its inevitable that the LS would take over as it can't match the LS
325hp, She’s a Beast Man.. Out of all those old Aussie Muscle Cars Love the Lx, Lh Tory Design… My first Car in ‘96’ was a 74 Red Lh, Red 253 Motor., Bought for $1400, Good Nic.. I Should never of sold It 😞
Yep, same old story, who knew how much the value would increase! Thanks for your feedback brother!
nothing wrong with the 308 I did a 327 off set grind stroker in my lx SS ran 11.6 back when it was a big deal to break the 12 second et no fancy heads just the old B castings, ported by Peter Micheals
Awesome car, nice note, the staff know what they doing, and a barra will never ever sound as good no matter what anyone says!! Good stuff!! 👌🇦🇺
@@job7016 cheers, I have to agree 👍
Update - I've bought a 600 vacuum secondaries square bore to experiment with. It will be interesting to see if it removes the flat spot, but I don't want to upset the AFR which was excellent when dyno'd.
600 vac second will be perfect for that motor. What I've got on my 308 with similar specs
sweet ride, took me back to carb days when you pumped the throttle before turning the key.
@@MrPsiclone666 lol yep, something the younger ones wouldn't understand!
Excellent looking Torana
@@jimclarke1108 thanks mate, I love it but don't look too close 😁
285rwhp is pretty healthy and remember it is pushing around a 1200kg car not a 1600kg+ late model
@@Surly34 so true although from memory it was around 1450kg when I got it engineered. Probably that power-sapping lug of a Ford 9 inch diff lol.
what you would expect fpr that combo, congrats on a beautiful build, great street car with plenty of poke to have fun. I can hear all the "1000HP Barra " owners laughing already but they dont own a TORANA LOL
@@71honky lol cheers mate, it isn't always about horsepower! Old school fun when 300hp was plenty until you coughed up for a GM671 blower 😁
185hp!
@@DontForgetOldKolobok 285hp, or 286 to be precise (at the wheels)!
Carb to big is a myth , i run a reworked 1050 dominater SBC , 20mpg no flat spots , tunning carbs has advanced since the old days , air fuel gauge tune it were you drive on the Street
I don't disagree with what you're saying although time will tell. I've done a lot of CZcams searching since the dyno and there are a few things I want to check on my carb to hopefully remove the low-down flat spot. Failing that, I've bought a Holley 600 vacuum secondaries which I want to put a kit through and trial that. I forgot that I have a O2 sensor bung in my extractors which I could use to hook up a an AFR monitor gauge which will help too!
I would keep the 700 double pumper I have one on my 308 torana my torana made 292hpatw power when built was 380hp at the fw 2 speed glide and 9 inch diff. Still running hard now
Thanks for the feedback. That will most likely be the end game but I've bought a 600 vacuum sec for experimenting.
I upgraded from a 600 to 650dp and it ran so much better that i thought I had fuel injection
Love the Tori mate! Wish I could afford one! ❤🔥🔥🔥
@@eezee187 there's something out there for everyone although I have to admit the value has gone up since I bought mine about 12 years ago! Cheers and thanks for watching 👍
Fantastic car mate. Great numbers. Have to agree with the carby!
I’m running a mild 318 in my Chrysler and that’s only got an Edelbrock 500 on it but it performs very well.
I’ve often wondered if it would benefit from jumping up to a 600 carby?
Dunno 🤷♂️
I run a eddy 600 on my 318. Runs great. No 1/4 mile times yet. Will have them by end of 24
Cheers mate, yep often it is just a case of trial and error. There's a level of adjustment with jets, throttle cams etc although the venturi may just be too big.
@@markgrovenor389 I have not touched the heads on mine yet as they’re very expensive but had had a mild cam installed with all the bolt on goodies. Extractors,exhaust,intake,hei ignition and carby. Goes very well but mine only made 210 at the wheels so perhaps one day I’ll do the heads ?
I’ve been told that the biggest let down in the 318 is the pistons but if I’m going to go that far then I may as well keep saving and do a stroker kit?
And that of course means engine out again. Don’t know if I can be bothered to be honest. It runs fantastic now so why mess with it.
Hmmmm 🤔
@@Tk-ou9ec there's nothing wrong with 210 hp at the wheels. You and I are not looking to win any horsepower hero competitions and after you reach a certain point every extra hp starts to cost more! I may have the advantage of higher compression with the flat top pistons. Regardless, the main thing is you can cruise and enjoy the ride with that old school charm and V8 burble. That's what counts! 😎
@@markgrovenor389 agreed.
Love the old school.
dash is pretty cool !
@@sixhunt cheers, they are Speedhut gauges I bought from the U.S. You can choose the style, font and colour so I tried to stay true to the original LX design as much as possible.
Nice car mate!
@@fishingking6337 cheers, much appreciated 👍
Cool. Nice tori mate. 😎👍
Thanks 👍
304ci from vn commodores not 308ci but decent power and sounds great
Cheers, yeah I listed it as a VN Commodore 304 in the beginning of the vid. A lot of people interchange 304 with 308. I think the main difference to the block was no hole for a mechanical fuel pump and the cam wouldn't have the lobe for the fuel pump. Other than that I think it was pretty much the same block.
11.18 dead hole sounds crank speed? Hope not, nice looking Torana miss my one. Maybe choped a lobe of cam. :)
I went back to listen but couldn't pick it on my phone speaker. Can you give more details of what you are hearing?
@@markgrovenor389 Hello mark, 11: 17 there is a noise (sounds like detonation) but only on one piston, noticeable on second pull but drops off with revs. Maybe just a leak at the header on one cylinder. I had my computer speaker on loud as weekend and few tins. Hopefully all is good
@@desmondwright5463 yeah I can hear what you are referring to, if anything I would say potentially the headers or exhaust as it is the oldest and worst part of the engine. I will keep an ear out when I bring it for another run.
Outstanding old-school work Mark.
Just a dash of the Brave New World.
Where did you get the gauges for your car?
Are these from Heath with the Torana hatch?
That’s a dash from Peter Nash I’m betting
@@johnszwede8516Both wrong lol! I first saw the gauges in Simon Reid's hatch (Sydney Torana Club) and bought a set myself. I'm proud to say I designed a casing and wired it to the original cluster plug myself, before seeing any examples from Heath or Peter. I am sure theirs are a cleaner finish (I have since followed both of them and seen their excellent work) although I was happy with what I achieved by myself!
One happy dyno
Honestly hub dynos show higher figures than roller dynos
Don’t think I’m putting you down or anything
But with the nine inch and not high comp engine I honestly think it would be closer to a genuine 175-200 rear wheel
A really good healthy 5 litre average 155-165rwhp without mods put a nine 9️⃣ inch into the driveline and you lose 45-65 hp
Over the std banjo diff you would be better off with a built borgwarner out of a vn vp commodore lighter and plenty strong enough for your power levels
Who knows? I did ask about the calibration before the dyno run and whilst it hadn't been done recently, they were confident it was accurate. Hub dyno's are a direct drive so they will be higher if that means no possible wheel spin from drum dyno's. As far as the engine goes, it is 30 thou overbore with flat top pistons and over 10:1 compression, Crane 884401 cam, 700 double pumper carb and open exhaust with extractors. I agree with the 9" diff sapping power but overall, I'm confident it puts out a healthy figure.
What was the torque? That dual plane air gap is beautiful.
382Nm at the wheels. Yes the Edelbrock manifold is still low enough to close the bonnet with the reverse scoop while letting some cool air flow through it!
Nice car mate. Where were the fuel mixtures and did they try different timing settings?
@@chriscarey3625 The afr was perfect through the whole rev range so they didn't need to change anything there. The timing was done a little while ago and there was no pinging although there is always the chance it could improve with a tiny bit more timing.
@@markgrovenor389 stay with the 700. A quadrajet was 720 CFM. Did you do valve springs? A bit strange how it started to fall over at 5 and a 1/2
@@chriscarey3625yep it's got new double valve springs. I have heard the quadrajet flowed in the 700's although I noticed they have much smaller primary venturis compared to the Holley. Also I assume they are a vacuum secondary set up too? The guys couldn't feel the flat spot on the dyno but it's very noticeable on the road at low reva. Maybe a quadrajet is the way to go 🤔
@@chriscarey3625I was also surprised about the power curve dropping off. I posted the description of the am model straight from Crane which suggests it should pull to 6500.... I set the redline warning lights at 5000 for a safe margin, which may have baulked Shane when doing the power runs, although I haven't set the MSD rev limiter and I know I have often brought it over 6500 and it is still pulling strong.
Shes a clean car, Id have to agree with going for a 600. Should improve the drivability.
Cheers, if I can pick one up at a decent price to experiment with I will definitely be trying it.
@@markgrovenor389 Get the 650 double pumper. I had my first LH SLR 5000 torana back in 1977. My brother in law too. I bought my car already cammed and heads with headers. I went from the original quadrajet to a 650 Holley and night and day difference after tuned.
Looks like a Vauxhall.
Lol you will have to let me know which model? The Torana is a well respected part of Holden history but every model has influences from other GM products to some degree....
The HB Torana (the one that nobody talks about) was a rebadged Vauxhall Viva. Subsequent Torana models were an evolution of the HB, and also incorporated GM styling cues so you can see similarities to other GM cars. Same story as the Opel/Vauxhall Rekord and Holden Commodore. The Holden Gemini was a locally manufactured Isuzu Gemini. Great Aussie cars! Unfortunately Australia never got any derivatives of the Opel Ascona or Opel Manta.
