Ford built 300 GTHO Phase III, 200 cars for the 3.25:1 and 3.50:1 rear axle ratios and 100 cars for the alternative 3.91:1 ratio rear axle would be in line with the CAMS rules for 1971 Group E.

According to the Ford documentation they fitted 200 cars with the standard 3.25 ratio, 50 with the "optional" 3.50 ratio and the other 50 with the "optional" 3.90 ratio.

Yeah, so what? They could have fitted all 300 Phase III cars with the 3.91:1 ratio diff, or the 3.25:1 or the 3.50:1 or any combination thereof under the 1970 and 1971 Group E rear axle ratio rules.

The important thing is that they needed to build a minimum of 100 cars, regardless of the rear axle ratio fitted, to allow homologation of the alternative 3.91:1 ratio diff.

Under the 1970 & 1971 C.A.M.S. Group E Series Production Touring Cars Rules a manufacturer was required to have fitted a minimum of 200 cars with one diff ratio and 100 cars with any "optional" or "alternative" diff ratio. This required a minimum of 300 cars and why Holden produced 300 1971 CK's. In 1970 Holden produced 300 9/70 & 10/70 LC GTR XU-1,s.

You might not be smoking pot but you could sure use a full stop every once in a while. Surely?
I had CK car once. I've not seen it since I sold it but there's no reason I can think of why it wouldn't still be around.

Either you have not read the 1970 or 1971 CAMS Group E Series Production rules pertaining to rear axle ratios or you have very poor comprehension of the written English language.

 

Holden produced 300 (or thereabout) CK XU1s but it wasn't for homologation of diff ratios that had already been homologated by the first 200 LC XU1 built back in 1970.

[FLY_AGAIN_XU-1]

 The first 200 LC XU1 built back in 1970.

 

Under the 1970 C.A.M.S. Group E Series Production Touring Cars Rules a manufacturer was required to build a minimum of 200 cars to be eligible to race. The next 200 8/70 LC GTR XU-1,s allowed the homologation of the baffles in the tank and diff housing. The next 300 9/70 & 10/70 LC GTR XU-1,s completed the homologation of the baffles in the tank and diff housing, 200 required. The final 100 cars homologated the optional 3.08 diff ratio. In total Holden produced a total of 700 1970 LC GTR XU-1,s.

You do understand that the 1970 race season is a completely different race season to the 1971 race season don't you ? and you do understand what the term "Eligible" or "Eligibility" means ?

The 200 2/71 LC GTR XU-1,s produced by Holden were for Eligibility into the 1971 race season.

Dealer Service Letters were homologations? I must say you have a very overactive imagination.

An extra 100 cars built for a diff ratio that was already homologated by the first 200 1970 LC XU1 built. You must be on some really good drugs.

This can be found in either the 1970 or 1971 F.I.A. Rules. In 1970 & 1971 the 3.36 diff ratio was standard fitment on the LC GTR XU-1 with the 3.08 being available as an option.

You don't really take much notice of what you are quoting as fact do you!

Go back and have a look at where you found that clause in the FIA Motorsport yearbook.

Now take notice of the Group it applies to. You will find that optional diff ratio clause only applies to FIA Group 2 'Special Touring Cars' which is the equivalent of CAMS Group C 'Improved Production Touring Cars'

FIA Group 1 ' Series Production Touring Cars' are the rules you need to look at, they are the equivalent of CAMS Group E Series Production.

 

You are the one who does not have a fcuking clue.

No difference at all. All manufacturers had to comply with the same rules.

[FLY_AGAIN_XU-1]

All manufacturers were required to build a minimum of 200 cars to be eligible.

300 : 1971 Ford Falcon GT HO Phase III ( Diff ratios 3.25, 3.5, 3.91 )

300 : 1971 Holden Torana CK LC GTR XU-1 ( Diff ratios 3.36, 3.08 )

316 : 1971 Chrysler Charger RT E38 ( Diff ratios 3.23, 3.5 )

 

Now all you need to do is explain why they were required to build a minimum of 300......

I don't NEED to explain anything to you. You are the one who concocted the BS fairytale that every XU1 was built to fulfil a CAMS requirement.

 

Facts are facts. The CAMS Group E Series Production rules for 1967, 1968, 1969, 1970, 1971 allowed a manufacturer to gain recognition of TWO different rear axle ratios every time the minimum production of the model was built.

 

ie: The 1st 200 Australian cars or 5000 cars if built overseas (1970 & 71) = recognition of 2 axle ratios, and then the possibility of recognition of another 2 different ratios every time the minimum production of the model is reached thereafter.

LOL, Still clutching at straws.

 

A baffled differential housing in not a strengthened housing/suspension member.

And even if it was the options clause in those FIA rules for Special Production Touring Cars (Group II) did not require any cars to be manufactured with the option fitted.

The manufacturer was only required to produce a minimum of 100 components and make said option available as a spare part and have that optional part listed in their spare parts catalogue.

 

Holden did neither in relation to 'Dealer fitted baffles' to XU1 diff housings as there was no requirement for them to do so.

Hell, the baffled diff housings fitted to the CK XU1s was so important that it didn't even rate a mention in the CK evolution form 2/2E.

 

The CAMS did NOT require manufacturers to build cars for Dealer Service Letters.
