Pics of vintages I find/see on the net.

What about alloy 12547 that was raced?

 

Thank you I mixed the automobile magazines

 

I would say it can’t be considered as a road version Daytona as it was a prototipo for the Daytona Competizione

 

What was different about it and what Competizione features did it have to make it a prototype for the Competizione apart from an alloy body? Looked identical to 12653.

 

12547 was sold new to Ennio Gherardi of Brindisi, Italy.
Quickly became a NART racer for Grossman-Posey for the Le Mans 24 hrs practice in April 1969, race #16, crashed by Grossmann who collided with the NART Dino driven by Ricardo Rodriguez, NART entry withdrawn.

Thank you Marcel for these informations. That’s why I think both of them are different : one was built for a friend of Enzo for road use, the other was built for the purpose of racing.

 

What evidence is there that 12547 was built for racing?

 

You are right it may be just my way of thinking but the car was built in May 1969 and was at Le Mans on 15th of June 1969, so I just assume it was built on purpose

 

Here's the ex Luciano Conti 12653 when it arrived from Italy at Seaside Motors, a dealer located in Yokohama, Japan, on 26 October 1971, as a used car.

Not to be confused with Ricardo Rodriguez, Pedro's brother. This fellow was an American who sometimes competed as Richard Rodriguez.

 

Which serial number Chinetti 365 GTB/4 was loaned to Car & Driver magazine in 1969? The 12467 doesn't line up date wise.

I too am curious what the actual difference between 12653 and 12547 is in terms of how they each left the factory. I understand how their lives differed after they left, but were they not built to the same specification by Ferrari?

 

12547 was completed 21 May 1969. New to Ennio Gherardi, Brindisi, Italy.
12653 was completed 19 June 1969. New to Luciano Conti, Bologna, Italy.
Both born Rosso Chiaro 20-R-190 with Nero 8500 interior.

I can only add a little to 12547. I do have the Chassis Build Sheet for the car. It indicates the chassis, suspension and brakes were standard early Daytona. It does note the aluminum bodywork. I have no information regarding the engine specs or transaxle. However, I suspect they also were standard Daytona street versions.

 

What order of magnitude weight savings would you estimate between a steel body and aluminium for a Daytona, 275 GTB or 250 SWB?

A lazy Google search, with no knowledge of respective sheet gauge, tells me sheet AL is about 1/3 the weight of steel, but I'm not sure what the starting point would be for the production bodies.

If anyone knows the approximate weight of the pf production 250gt coupe body that would be something I'd be curious to know.

 

Amerikalei: I can be very precise about the 275 weights. A steel bodied 275 GTB weighs 2,757 lbs. and a alloy bodied 275 GTB weighs 2,608 lbs. Both cars were weighed with spare tire, jack and toolkit, but no fuel or driver. The cars were both weighed on our race scales. So, in the case of the GTB, an alloy car is 150 lbs. lighter than a steel car. I would expect a similar, or slightly greater difference with the Daytona.

 

what is the wt. of a typical Daytona coupe.
