F or F all Holden V8 cranks were made from nodular iron.

[xu2308]

I'll strand corrected Al but I think those were the engines first developed for F5000 use. 
 

 

Not sure the rumors were for the early L34 the X Block 308, I assume the early L34 Heads would have the X on them as well ????????

[xu2308]

Wonder if any HQ Holden 308 V8 Cars ended up with a XW7 Spec QT 308 Engine in them. As they were only two weeks from Production, one would think there would of been some Engines ready for production, Harry Firth told me that there were 200 Kits done to fit V8's into LJ's

All 253 and 308 cranks are cast nodular iron.

[Dr Terry]

F or F the intake manifold on the 2250 is smaller than the 186 engine

Sort of.

 

AFAIK they are the same basic casting & therefore size, but the inlet hole (carb throttle bore) is smaller for the smaller engine.

There have been a fair few 3/73 cast (going from memory) HJ style 308 blocks with X on the side turn up. I had heard that these were the F5000 engines. If early L34 got X as well then it'll probably just be a matter of the same castings being used prior to all of them changing getting ready for HJ engine production.

I've never heard of any turning up. If Dave Bennet did the heads he'd remember being given them back?

 

You are correct though, if the cars were two weeks away from initial production then the schedule would have seen everything ordered and most things ready to go. Probably not far from shipping all bits to the assembly plant(s) that were to build them. The wheels have turned up, so I wonder what happened to the other unique parts? There were people building these cars for people aftermarket so maybe they bought some of the special bits. Perhaps some of the bits were re-used for L34? Like valves, springs etc?

I haven't seen one but I've heard of people talk of finding development crankshafts in production engines. Remember the Holden V8 was to be ready for HK, and GMH's foundry capable of doing the cranks didn't start until mid 1967, so there must have been crankshafts different to the production ones around for development back into the earlier 60's whether they found their way into production engines or not. What they were made of I don't know. Remember though that GH used everything they could rather than scrap it. If perfectly good development stuff was useable it'd get used.

Dave Bennet did get the Nod to do the Heads for the XW7 Engines, my thinking is there would of been some Full engines done and ready for Production to be fitted, maybe only 20 Engines or more etc, as GMH hit the stop button in July 1972, so where did the Engines go,  there is Rumors of Ambulance Pack Donks you could order from Spare Parts that were Special Engines, but only Rumours.
 

[yel327]

fact or fiction Holden seriously thought about fitting a oil cooled disc brakes to the HG Monaro?

 

Fact. These were for Harry's baby with the LT1 engine. It was canned and the XU1 forced upon him by GMH. Harry wasn't happy from what I've heard!

If they escaped Al someone would have found a JT prefixed engine by now! Ambulance packs didn't appear until 1975, I have signed off paperwork for them from late 1974. The edict was "make it look like it never happened" so my guess is any engines that were built would have been stripped and the parts re-used elsewhere. Perhaps Dave got to keep the heads? Unless of course the engines were straight QT engines and would get a prefix at the assembly plant like was already the practice with 11QT for Statesman and later XQL for LX Torana. Then they could have been slotted into HQ's.

X2 HR Holdens can be identified by the tags.

Part true. You can for those with bodies built in the Dandenong body plant.

[wot179]

Tell me more.

I was always of the impression that it was false and that they could only be identified by things like the different wiring harness, as well as the obvious things like gauges, carbs and badges.

Dandenong body plant stamped the vehicle package code (or driveline code or whatever it was called for HD-HR) on the INSERT line of the body plate. You often see the code on original vehicle books, normally 3 digits but a 4th digit added when 186S appeared. The code was applicable across all plants but only Dandenong stamped it. Same basic concept as Acacia Ridge stamping the special vehicle package codes on their body plates in the 70's, like XV4, XW8, XX7, XU3, A9K etc 

 

Here is a picture of one: http://www.fastlane....&TOPIC_ID=20274

 

Nowhere getting a complete list yet, but have nailed the basics to know what engine was in the car originally.

The Full Spec XW7 Engine that was in the Pink GTR V8 Prototype was a QT Engine and the one in Joe's Orange Car was a QT Engine as well, maybe the QT was the Prefix or not.

Maybe Dave just kept the heads and used them else where etc, like you said, make like the program never happened and the Engines were pulled apart etc. Lucky the 3-GTR's survived that directive.

[yel327]

They would have used whatever in the prototypes AL, but more than likely the production cars would have had a different prefix just like LJ had JL, HG had GL, CF had FL - neither just used HQ's QL. That or something in front like 11QT or XQL did.

Out of interest, what would have to have changed on a QT long engine to fit it in an LJ? A GMH long engine would be sump to manifold, bellhousing to water pump plus exhaust manifolds.

[xu2308]

They made new engine mounts for the XW7 Engine, looks like your normal HQ type engine mount but it had a 100mm spacer in the mount and they made a New sump with wings on the side of the sump a bit like how the phase 4 falcon sump is, and the exhaust manifolds would be like the HQ ones or HG 308 Exhaust Manifolds etc and the passenger side trailing arm lip needs to be removed that is on the side trailing arm on a LJ as the starter motor might fowl it and there were two steering knuckles used on the steering so to clear the engine block and exhaust.

But after them Mods the donk is in, Harry and Holden had that sorted for production, there is a drawing of the XW7 Sump and I happened to have it. So a JT Engine for 308

It may well have been JT. Makes more sense than anything else - odds on i'd say.

[N/A-PWR]

Fact, there has been one for sale for a while Jason.

Did the 1969 model have rear seat belts.
