Building a Gr4 replica

Kristian, great to see you working on the GR4 again - seems like the drive in the Grønne djævelskab did you some good :-)  There is a funny discussion about it on the FB page for Copenhagen Classic Car Group.

Cheers, Tim.

Yes, the green PB creates quite a stirr everywhere it turns up.

Regarding the carburators used, I do not know which one they are referring to in the supplementary parts list, but in the original Gr4 hand written part list for the Gr4 program that contain all the parts the factory tested and ended up using (that I coincidently am in possession of) they list a R4575 Holley 1050 dominator, that I think was used on the first Gr4s (see picture)?

They do not list the carp for the Gr3s, but they refer to the 390 HP K625J Boss 351 engine for some applications (likely Gr3??) and of course the 520 HP (Bud Moore) engine for the gr4? (see picture)

Hi Kristian, very cool. Great info. And I think you are right about the K625J, there are plenty of references on the internet to that being in the 1971 351 Boss Mustang. So maybe it used the same carb too in the Pantera GR3.

Cheers, Tim.

Hi Tim, I still have what I presume is the original Holley for my GR3 at home. I will have a look when I get to it and perhaps read some numbers off. Give me a couple of weeks........

Sounds great, many thanks! cheers Tim

a looong while back, there was a road test of a Gr-3 Pantera by Peter Revson reported in a car magazine. In the story Revson called out the particular Holley used. I think George Pence also mentioned which one it was in one of his 'stickys' on this site- which I can no longer access.

Where can I get that Blade spoiler  for that Grp4 recreation  your building, I too am running  a belt Drive a Danny B unit and Ingles electronic  FI that look like webbers,Does anyone  have pictures  of the 2 different  types of Revson front spoilers?

I don't store photos but they're in the older threads. The original Revson spoiler is curvaceous and is level with the bottom of the original nose sheet metal. The later one has a small splitter molded into its shape. Never tried it, have no idea how it works. The ground clearance looks quite close to the original. As I said in the previous post, Larry Stock's Pantera Parts Connection in NV has all those spoilers and might even have shots on his comprehensive web site.

You can't buy that spoiler anywhere.

It is a one-off that I made in 1,5 mm aluminum. It was made as a repica of the early Gr4 1972-73 gr4 racers from studying period correct pictures.

It's actually a 3-piece design that's riveted together in the center - the thinking being, that while racing the car, damaged pieces of the spoiler can easily be replaced.

I actually made another for a bloke in Germany, but even then, I can't guarantee that it will fit other cars than mine, as the placement of the flares may vary from car to car.

It's also designed to work with/wrap around the oilcooler, so running the spoiler w/o the cooler will look odd.
