Model history:

With Alejandro De Tomaso's deeply ingrained love for racing, it was no surprise when a

competizione Pantera was unveiled in late 1971. Built to contest the FIA's now legendary

Group 4 category, it would most notably go up against factory-built race cars from Ferrari,

Porsche and Chevrolet. The starting point was a lightweight Tipo 874A chassis, almost e-

very part of which had been extensively drilled. This was equipped with shorter suspension

uprights, solid bronze bushes and adjustable Koni shock absorbers. Ride-height was thus

totally variable as were the larger diameter anti-roll bars front and rear.

The shock absorber towers were modified to accommodate beautiful new Campagnolo

wheels. Ten and 14-inches wide at the front and back respectively, these cast magnesium

rims had a 15-inch diameter and fronted bigger Lockheed ventilated disc brakes. Cooling

tubes were now all-alloy, quick-ratio steering racks being fitted along with twin 60-litre fuel

tanks. While a projected weight of around 1100kg had originally been targeted, Porsche

were so concerned about the Pantera's arrival that they forced the FIA into homologating

the Group 4 version (or GT4) at 1250kg. To overcome this, the car needed a race-spec

engine of the highest order and considering the American's level of expertise with Ford

motors, it must have seemed appropriate to look to the US first. It was eventually decided

that Bud Moore-prepared Boss 351 motors would be flown over and installed at Modena.

They boasted full racing camshafts and valve springs, TRW forged pistons, large capacity

oil pans and titanium valves. Bud Moore also fitted a single Holley Racing 1150 CFM four-

barrel carburettor and yanked the compression up to 12.0:1. Displacement was unaltered

from the stock Pantera's 5763cc thanks to a bore and stroke of 101.6mm x 88.9mm. Other

standard features that were retained included rockers, connecting rods and the solid lifters

and crankshaft.

Although De Tomaso quoted around 500bhp for these engines, early cars were typically

producing around 440bhp at 7000rpm. This was soon upped to 470bhp for the 1972 Le

Mans race (where the Pantera's also ran 850 CFM carbs), enough to propel the GT4 to

180mph down the Mulsanne Straight. The engine was coupled to another more-or-less

stock item in ZF's close ratio five-speed gearbox, a heavy duty single plate clutch comple-

ting the mechanical upgrades. For the body, standard steel shells were taken from the

production line and fitted with light alloy front lids, engine covers and doors.

Bulbous fibreglass wheel arch extensions were pop-riveted on to accommodate the wide

Campagnolo wheels and gave the car an extremely aggressive look which was enhanced

by the deep front spoiler and matt-black finish for the front lid, engine cover and sills. No

front bumpers were fitted nor any rustproofing applied, the Group 4 Pantera's using two

types of tail lights, some early cars getting vertically divided clusters as pictured here, o-

thers getting production-style items. The cabin was stripped bare and got no soundproo-

fing to speak of, just the stock vinyl-covered dash and centre console remaining from the

production Pantera. Lightweight bucket seats with vinyl bolsters and cloth centres were

installed along with more basic door trim, Plexiglas side windows and a small diameter

steering wheel. Each car also got drilled aluminium pedals, a roll cage, safety harnesses

and a cut-off switch wired into where the radio would originally have been. The first of 14

cars (chassis 2263) was completed on December 12th 1971, the last (2874) rolling out litt-

le more than a year later on 22nd December 1972. Customers included wealthy privateers

like Herbert Muller, Vincenzo "Pooky" Cazzago and Aldo "Alval" Valtellina. The De Tomaso

Concessionaires for Spain, France (Franco-Britannic) and Belgium (Claude Dubois) also

had their own cars.

After Herbie Muller and Mike Parkes had posted the fifth quickest time outright and the fas-

test lap set by a Group 4 car at the Le Mans trials in March 1972, the Pantera's race debut

proper came in April at the Montlhery Grand Prix (a round of the inaugural European GT

Championship). Driving chassis 2860 for Claude Dubois, Jean-Marie Jacquemin finished

second overall whilst Vincenzo Cazzago placed 13th and Muller retired. Group 4 Pantera's

subsequently went onto win the 1000-kilometre World Manufacturers Championship race's

at Monza (2342), Spa (2860) and the Österreichring (2861). Le Mans proved something of

a washout though with just one of the four cars finishing. Despite the Pantera's European

GT Championship campaign yielding just a solitary win (for 2859 at Nivelles), the format of

these events which tended to resemble sprint rather than endurance races seemed to ap-

peal to De Tomaso. This led to the factory entering its own works Group 4 Pantera (2873,

built December 13th 1972) in three rounds of the 1973 EGTC. By this time De Tomaso had

began building competition motors in-house at Modena where they were dry-sumped, fit-

ted with four twin choke Weber 48 IDA downdraught carbs, gas-flowed cylinder heads and

a crane-type camshaft. The crankshaft was now fully polished and balanced, as were the

connecting rods.

A new exhaust system too meant output had risen to 490bhp at 7000rpm. Compression

remained unchanged at 12.0:1, all that power being fed through a new heavy-duty ZF five-

speed gearbox that could more adequately deal with the massive torque loads. The works

car got wheeled out for the EGTC rounds at Imola and Nivelles (driven by Mike Parkes)

and Hockenheim (Clay Regazzoni). Parkes won comfortably at Imola as did Regazzoni in

Germany. The factory also supported a pair of cars despatched to Roberto Angiolini's Jolly

Club outfit (2862 and 2872). But despite already having proven the Pantera was good e-

nough to beat the cream of the worlds sports car manufacturers, undoubtedly the cars fi-

nest moment was yet to come. For the 1973 Giro d'Italia, a gruelling three-day mix of cir-

cuit races, timed stages and regulation road routes, De Tomaso's ex-Parkes/Regazzoni

EGTC works GT4 (2873) was handed over to the Jolly Club for Mario Casoni to drive. He

duly won what had become Italy's biggest road race since the Mille Miglia and in the pro-

cess secured perhaps De Tomaso's most glittering outright win.

Specific history of this car:

This specific car has been sold new to the Italian Vincenzo 'Pooky' Cazzago, Italy who had

the car prepared by Scuderia Brescia Corse. The car was then entered at the following ra-

ces:

• 16 April 1972: Montlhery - V. Cazzago, 13th overall

• 25 April 1972: Monza 1000km - V. Cazzago / M. Casoni, 5th overall, 1st in class

• 10-11 June 1972: 24 hours of Le Mans - V. Cazzago / M. Casoni / E. Pasolini / G. Moretti,

DNQ

• 25 June 1972: Monza Coppa Gran Turismo Speciale - V. Cazzago , 1st overall

• 10September 1972: Monza Coppa Intereuropa - V. Cazzago, 6th overall

After the 1972 season the car was sold to Gianpiero Moretti for Momo Racing Team. Mo-

retti raced 2343 throughout 1973 and '74 mainly at Italian races.
