You forgot to mention it was sold with 202 in it

yes but it was first rego with Vic Roads as a 308 V8, so could of easy turned back to a 308 V8 in Vic, and i dident steal the thread,
as LXSS350 said there was no factory Torana that would do the speeds of the Phase 3, well the V8 XU-1 would of done them speeds of the phase 3, and the V8 LJ was only days away from been built, yes days away, there are XW-7 Parts Sheets for the V8 LJ, if u did not know this, If the Supercar Story was a week later, the V8 LJ would of been a goer.

Whats the date of the article?
It's owned by an Adelaide enthusiast, there is nothing at all to say he hadn't done anything to it, just like you're claiming the Suttons car was doctored to underperform, who is to say this car had not had an exhaust and intake, or any other mods, or that it's a HO optioned car?

[REDA9X]

As per usual never let the facts get in the way of a good story.

If you can find ANYWHERE where I said the A9X engine was as good as or better than the L34 then I'll shout you a carton.

What i said was the L34 engine had all the good bits in it, but stock off the showroom floor they were not the fire breathing rocket some people seem to think they were. Like any engine they need to breath, 310HP from a bog stock L34 engine, yet Harry was getting 350 from a race engine on a good day, come on. If that was true, all Harry needed to do was go to Holden change the exhaust and fit a better aircleaner and it was race on, why even bother with changing cams and HO kits. Most dynos I've ever seen claim a 30% loss in drivetrain, I know Harry's old dyno did. A 73 Bathurst XU1 would run rings around a stock L34 on the day There is no reason for this article to mention the HO kit, the bloke writing it probably wouldn't have even known of the existance, the article says very little really. and apparently a year after the cars release.

But I'm over repeating myself, it's just become a waste of time because no matter what I type it will be twisted into something to suit yourself.

The 1972 Supercar Scare was so over hyped i reckon, when you could buy a Lambo or Ferrari in 1972, Holden should of been loud and proud i thought in 1974 with the L34 Torana

[xu2308]

Yeah its unlike these modern times, where the 300 kw plus cars from HSV and Ford's FPV, Should or released the Phase 4's and
the V8 LJ XU-1's but under Group C Rules, GMH and Ford should of talked turkey with the NSW Transport Minister of the day, instead of backing right down, but thats how it all washed up in 1972.

[xu2308]

But we got the L34 and A9X Torana from the washup of the Supercar Scare, a good deal in the end

It’s not about anti compaining, it’s about facts and old wives tales. I’m sorry but what you have just written has actually proved my point.
From the original article
“185 bhp on dyno at rear wheels at 5000rpm.Allowing for loss of 40% equates to 310 engine hp”
From what you said
“i recken as a guess mines about 310fwbhp with the same mods as the two above, that makes it about 240rwhp which is an extra
55rwhp more than a dead stock L34.”
You are saying your car has the same figure they quote at the engine “as a guess of 40% drive train loss” yet you claim 240 at the wheels while they quote 185 at the wheels.
You say your car has mods the same as theirs, yet according to what it says in the article with drivetrain loss you make the same HP at the engine????
i know of 2 standard L34s that had 2" exhuast, 14"inch open aircleaners and a cam around 500thou lift less than 300adv duration, nothing else done and they produced 240 bhp at the back wheels. makes 185bhp more than plausible.
You also say
there is not a huge loss of power thru an aussie and banjo, compared to a ford with toploader and nine inch diff

Now, with all this in mind, apply about a 30% drive train loss and equate that to 185HP at the rear wheels you would end up with around 265Hp at the engine. That sounds more plausable for a stock L34 off the showroom floor with NOTHING done to it.

As for an exhaust and intake giving you 40HP, I believe it’s very possible on an L34.
Consider this as a comparison. The VR 5.0l produced 165kw at the engine, the HSV version produced 185 kw. That’s around 27 HP improvement. What was done to them? Just exhaust, intake and timing (chip). The fact was the exhaust and intake on the stock VR was no where near as restrictive as the stock exhaust and intake on the L34 so you would expect a bigger improvement with similar mods to an L34.
My own VR SS was fitted with a better exhaust (full twin rather than two into one) that the HSV version produced 12 more rear KW than the HSV version. The HSV version was 123kw, whilst mine was 135kw, so it just proves how much difference a good exhaust can really make. The VR lost almost right on 30% through the drive train and it would lose more than the L34 did percentage wise to the rear wheels.

thanks Red, you explained my point very well, i believe 185rwhp correct for a showroom L34,

i know that adding a 500thou lift with under 300adv duration hyd cam, 2"exhaust,opentype aircleaner and good tune makes 240rwhp in a standard aircleaner.

more simply put stock L34=low 14,s with mentioned mods mid 13,s

Thanks Yella, I'm glad you took what I wrote as just clearing things up and not some personal attack. I think 185 at the wheels would be about right for a stock car with 30% loss through the drivetrain. 310Hp at the engine stock I don't think so, with a few simple mods yep I believe 310 at the engine for an L34 would be easy enough.
The other issue is of course what dratio is in the L34 to do the quarter, the one in the SLR5000/L34 comparison was 2.78 the same as the SLR5000. To put a 3.08 rear end car in would make a difference.
Just as a matter of interest had had some fun in my VR SS against my mate Gregs ( a few guys will know Greg and the car) fairly stock L34 at the time coming out of Lithgow. In 5th he was with me I couldn't get away but he couldn't gain back to 4th I slowly edged away. When I sold the VR I bought a VT 220i (factory stroker engine) manual Senator. Now it's a lot heavier than the VR and 220KW equates to 300HP (by HSV's very liberal figures) but I can tell you it would eat the VR.
