UOC 741  was different from the other cars. Firstly it was a BN4 whereas the others were BN6s. It was an older 1956 car that had received the 6 port head and other modifications including 4 wheel disc brakes and a blue printed engine, when it ran in the Mille Miglia. Its colour has caused some speculation. In the team picture it appears almost BRG, although the duo tone feature is hidden. BRG was not a factory colour for 100-Sixs so this is unlikley. In the picture above, and others I have see in Herve Chevalier`s collection, it appears to be blue - somewhat like the BN3. In some books it is referred to as Duo Green and I think  this is most likey correct and that the car was Pacific Green over Florida Green which would account for the "bluey" colour in some photos.. This was a production colour combination available at the time.

Interesting non works modification to UOC 741!!!!! Although this photo is in black and white if you look at the tones of the main colour and the colour below the swage line this gives support to the belief that this car was Pacific Green over Florida Green

- Standard 2,639 cc engine - Polished and ported head - 3/4 Race Cam (very similar spec to what was much later installed in the BJ8 ) - Six Port Head with twin SU`s, probably 13/4" - (possibly 2" later) - Side exit exhaust - larger fuel tank - Raised suspension - Four wheel disc brakes

100-Six

The first outing for the 100-Six in an international rally was in the 1957 Sestriere Rally when the future Mille Miglia car UOC 741 was driven by Tommy Wisdom accompanied by his daughter Ann. (Later to partner Pat Moss with much success).This car was a 1956 ex-press demonstrator  that was later modified at Warwick. It  was then driven by Wisdom in the 1957 Mille Miglia, equiped with the new six port head, blue printed engine and four wheel disc brakes, it finished a creditable 37th overall. The first BMC team entry of Healeys was in the 1958 Apine Rally

The Ultimate Works Healey - aluminium engine - triple webers - side cut out exhaust - wing vents - flared arches - minilites - 140 mph

When people think of a Works Healey they probably think of a car like the one below. This car however was the end of the line of the development of the Works cars and has many more modifications than the original 100-Sixs. The car below was in fact prepared for Timo Makinen to drive in the 1967 RAC Rally. Works Healeys had not been run for two years and the car actually belonged to Peter Browning at the time. Makinen then changed his mind and Rauno Aaltonen agreed to drive it. In fact it never ran as the rally was cancelled due to an outbreak of foot and mouth desease. The car is the ultimate devlopment of the Works Healey and was fitted with an all aluminium engine (not just the head!) It was capable of 0 -60 mph in 7.5 seconds and a 140 mph.

100-Six Works Specification The 100-Six specs were much closer to the production model than the car above. They also differ from the later 3000s in several aspects as the Works cars continued to evolve  from 1958 through to 1965. Even the 100-Six cars evolved during their brief career from 1958 to 1959. Body and Exterior Features - The PMO cars were new and painted Signal Red. (TON 792 - a `used` car, was Colorado Red) -  Black hardtops - not the more commonly known White ones - vent was added later   - Two air vents in the bonnet facing backwards either side of the bonnet ridge. - They never had triangular vents in the side of the wings -  They  never had raised boot lids to accomodate a second spare wheel - Headlight wire mesh guards and two unprotected spotlights - 100-Six grill with two small sections cut away asymetrically on either side. - Later in 1958 the grill was removed and replaced with the well known wire mesh type - Bonnet hold down catches and a quick release bonnet pull were also added later in 1958 - 60 spoke wires, on normal width rims - they never had minilite wheels - They sometimes had bumpers fitted , depending on the class they were entered in. - No bonnet straps or hold downs
