I like crazy. Plenty of it here!
Reminds me of some old girlfriends.
This is another reason I like my LJs stuffed full of the biggest V8 and drivetrain I can find.

Some of the things you find ... :)

 

This is a link to the thread titled "150 1973 Bathurst Myth Busted" ..  http://www.gmh-toran...h-busted/page-2

 

 I draw your attention to post #46 ..   Take note that Anthony is happy to concede both 202 and 173 Dual Cast Blocks exist....  

 

Then look at the bottom picture in the same post..  The rusty old Dual Cast 202..   And if you have a magnifying glass, or you can blow up the size of the picture, you will see it has a cast number 3 ....   

 

So in your own words & pictures Anthony, you state that 173 Dual Cast Date Blocks exist .. 

 

And your pictures show that an everyday run of the mill 202 has a dual cast mark, and the number 3 ......  Please explain??

Ian,The same reason you will find a standard QL,JL 202 with the same cast date as a JP Example: 12D3 one of the cast dates for JP328 and higher. Public photo's from ebay 2014

Sorry then Anthony, I thought the you were pushing the point that Dual Date Casts, were important engine blocks ...  Here we have a Dual Date Cast 202 with a number 3 on the side......  and it is no more important than a Dual Date Cast JP with number 3 on the side...  or have I got it wrong again??

Ian,The same principle applies to standard JP blocks and with dual cast blocks left over blocks went into Torana JL's and HQ's. Example 12D3 JL327### is a cast date for late 4 month and 5 month 73 xu1,Also James JL363 dual cast block.

Cheers

See this is where I'm confused ...  I thought you said that the 150 list engines are all Dual Date Cast blocks with 3 on the side...  And the thing that makes them special is the Dual Date Cast marks, and the number 3.....  although you have not shown any evidence to back your comments..

 

Yet there seems to be many different engine blocks with Dual Date Cast's, from 173 to 202,  some QL some JP prefix ....  and with 3 on there side.. so whether the motor is a low performance motor, or a high performance motor, it seems to make no difference how many dates casts they have, or what number is on the side...

 

So, this is why I'm confused...

 

 Because I believe it has been shown to be true that Single Date Cast engines are in fact on the 150 list...

 

Others on this tread have said all along that there may well be Dual Date Cast engines on the 150 list, but it is the fact there on the list, and not the number of Date Casts that make the special..

 

And others have stated that their genuine JP engines don't all have a 3 on the side...

Not unexpected to find varying prefix blocks with the same cast date. They were casting hundreds of engine blocks each day to feed the production lines.

LJ's, HQ's and CF Bedfords all being made at the same time.

Dual cast date 173 engines are the fly in the XU1 ointment. Find out why GM-H produced dual cast date 173's and we will find the real reason why dual cast date 202's were produced.

Dual cast 173 engines certainly are the fly in the XU! ointment because they were never intended for a XU-1, the dual cast 202 was the engine intended for the XU-1, Dual cast 173 engines were intended for the 1971 LC GTR 173 ( CF ). These were the cars chosen to compete in the 1973 Manufacturers Championship and Bathurst in the under 3 litre class. At Bathurst in 1973 there were 2 Holden engines entered, a 173 & the 202. Dual cast blocks were designed to last and produce maximum horsepower. In 1973 both the 173 and 202 engines were Holdens top selling engines...........

Both the 173 & the 202 were unsuccessfull at Bathurst in 1973, though we soon forget that the XU-1 won everything else in 1973 & 1974 until the LH came along.........

 

It was all to do with motor racing, winning races and selling cars.......

Anyone in NZ reading this, please find an LJ from this period with a 138 with the second cast date. Then it'll be a cockroach in the ointment.

 

173 race cars - that is a bigger joke than the second date code used for XU1's - now there has to be 250 x 173's with the second date code?? Surely that is the case for eligibility for Group C as well? Are there CAMS homologation documents for a special 173 block too?

seems odd they would specifically make engines for the '73 race for the GTR's ?

 

there were only 3 GTR's entered in '72.  2 x listed as 2850's and another simply listed as a GTR...

 

Class B is also listed as 3,000 to 9,000 CP Units in the 72 programme... but I have no idea what a CP unit is ??

You'll struggle to find them as they were export only in that time period, but they do exist just not in Australia.

The one's send to nz if it's correct on the vin disc the 138 would be after CB 399 the CD399,s and CD402,s i have the cast dates are 20H3 after the dual cast period which the last cast is 10H3.

Yes Adam it's a load of crap.

Special 173 blocks for racing hahahahahahahahahahaha.

Keep clutching at straws boys. You've clutched at them before and they got very short very quickly didn't they.
