The Story of the Repco-Brabham V8 Racing Engine as conveyed in Repco Technical News Volume 12 No 2, November 1965…

This gem is from Michael Gasking’s Collection and is reproduced in all of its glory, this is the 1966 Tasman/F1 engine later more commonly referred to as ‘RB620’, its internal Repco Parts Co project code was ‘620’. It will be difficult to read on your ‘phone, a bit easier on a larger device!

We have covered this engine already in primotipo, click on the links at the end of the article for these stories. Just a couple of ‘editorial comments’ or observations.

RB620 and F1…

No mention is made of the engines F1 application so late in the piece, the new 3 litre F1 began on 1 January 1966. Brabham and Repco were playing their cards, understandably, close to their chest. Remember the RB620 V8 first ran in a car at 3 litres not 2.5, at Goodwood before racing in the non-championship South African GP, at Kyalami on 1 January 1966.

Melbourne motoring journalist Chris de Fraga, well known and respected by generations of Victorian enthusiasts is credited with first reporting Repco’s F1 plans in the Melbourne ‘Age’ in early October 1965, a report denied by Repco at the time. This document dated November 1965 was presumably circulated in that month or the following one.

Jack’s Lovechild…

Brabham’s parentage of the project is ignored in this largely technical treatise of the engine, Jack’s involvement not ‘front and centre’ in this public document given the need for F1 confidentiality.

‘The Men’…

The duo credited with the engine in the brochure are Chief Engineer of the Repco Parts Group, Frank Hallam and Project Engineer Phil Irving, the only guy missing, as stated above is Brabham. Its worth musing for a bit about the roles these three men played in the championship winning RB620.

In simple terms Jack was the engines conceptual designer- he pitched the Repco board a simple engine using the F85 Olds block as a base whose completed dimensions were to fit the existing BT19 chassis. Phil designed it, inclusive of its drawings. Jack provided both conceptual design and practical feedback to Phil on regular visits to Irving who was based near Brabhams early in 1964 as he progressed the engines design. All of the ‘RB620’ drawings were done by Phil and signed by him according to ex-Repco engineer and Repco Historian, Nigel Tait who has seen and reviewed them all in the process of archiving them with RMIT University, Melbourne, in recent years. Hallam was Repco Brabham Engines Pty. Ltd. General Manager and Chief Engineer. His role was primarily a management one although he had engineering oversight, his direct design and engineering input into RB620 something Hallam has sought to grab a greater share of down the decades.

After Irving’s death, Hallam in his book ‘Mr Repco Brabham’ comprehensively dumps all over Irving and seeks to take more credit than he is due for the ‘RB620’ engine inclusive of positioning Irving as its ‘draftsman’ – ‘draftsman casual’ in the employee list in his books Appendix. In fact all of the ‘Drawing Office Personnel’ listed are described as ‘draftsman’ despite several being degree qualified engineers. Hallam, on the other hand, formally qualified as a motor mechanic, lists himself as General Manager/Chief Engineer. The positioning he inaccurately seeks to convey is clear. In that context its interesting to see Phil’s title as ‘Project Engineer’ in this Repco publication of the day.

The very well known F1 engine designer and manufacturer John Judd joined the Repco Brabham Engines Maidstone design team at Jack Brabham’s behest in 1966. He pretty much unwittingly walked into a storm in terms of the final breakdown in the progressively declining working relationship between Hallam and Irving. Judds arrival at Maidstone was unannounced by Frank to Phil, the design leader at the time, thereby lighting the fuse for a final confrontation which was becoming increasingly inevitable.

Judd got the ‘rounds of the kitchen’ from Phil when he joined RBE according to both Phil’s autobiography and Frank’s book but Judd has this to say about Irving’s contribution to ‘RB620’ in a recent ‘Vintage Racecar’ magazine interview;

‘When Jack returned (to the UK) from the (1966) Tasman  series, he asked if I could go to Melbourne almost immediately, and work with Repco designing parts toward the next year’s engine. That lasted for about four months and I was back again for six months in 1967 working on the 1968 4-cam engine.’

‘The original 1966 engine had been designed almost 100% by Phil Irving of Velocette and HRD fame with input from Jack and Ron Tauranac, but Phil didn’t fit in well with the Repco corporate structure and fell out with his boss Frank Hallam. My insertion into an already fragile situation led to Phil leaving after I had been there two months or so, and to his replacement by Norm Wilson. Looking back at Jack’s 1966 World Championship winning engine, I believe it was largely the product of one man, Phil Irving, to an extent that is and will remain unique.’

Don’t get me wrong, Hallam played a vastly important role in marshalling Repco corporate resources to assemble the men and modern machines to build World Championship winning engines in 1966 and 1967. He was also a wonderful foil between the demanding requirements of the Repco Board and the daily dramas in Maidstone of building and servicing racing V8 engines so far from Brabham Racing Organisation’s Guildford base. But his contribution is more management than engineering detail of RB620 when objectively looked at in the context of all the published evidence and the views of those there at the time.

The antipathy between Irving and Hallam was and is well known, few Repco people want to go ‘on record’ about the topic, which is both understandable and frustrating at the same time. They, rightfully, recognise the contributions of both men. Irving’s book is respectful of Hallam, Hallam’s of Irving not so and was published well after Phil’s death- the shit-canning of Irving is grubby and un-Australian really. If you are going to ‘have a crack’ do so when the other dude can defend himself. Hallam’s book was contracted by him from Simon Pinder, the author. It is not objective as such (neither is Irving’s autobiography of course) but does add much to fill in the RBE story, the long interview with ’67 RB740 designer Norman Wilson is gold for example,  but the books quality varies from gold to ‘merde’ depending upon the chapter. One needs quite a lot of Repco knowledge to pick the chapters to treasure and those to treat with rather more circumspection.

Nigel Tait told me that Jack Brabham was very angry with a fair bit of the contents of the book- it would have been a good idea for the great man to have read its contents before writing the publications foreword! I will explore the relationship between Irving and Hallam, and Hallam’s claims, in detail, soon. In short, this Repco corporate piece puffs up Hallam’s racing background and downplays Irving’s, ‘twould be interesting to know who ‘signed off’ the content of this document before it’s publication.

Enjoy ‘The Story of The Repco-Brabham V8 Racing Engine’, its sensational. Wish I had it when Rodway Wolfe and I tackled the articles linked below 2 years ago!, having said that we have included a good bit of granular stuff not included in this official publication, so read together are not a bad crack at the ‘RB620’ subject…

Tailpiece: Repco Brabham Boys, Longford, March 1966…

Phil Irving, with collar and tie chats to Brabham whilst Frank Hallam at right susses the Brabham BT19’s suspension. Not sure what Roy Billington is up to. Note the long inlet trumpets of the Tasman 2.5 RBE620 V8. Its the engines 3rd race, South African GP then Sandown Tasman the week before Longford. Jack was 3rd with overheating and low fuel, Jackie Stewart won in a BRM P261 from Graham Hill’s sister BRM. Its 6 or 7 March 1966. BT19 was Jack’s F1 championship winning 1966 car, still in Oz owned by Repco (oldracephotos.com/Harold Ellis)

Jackie Stewart’s BRM P261 is pushed onto the Longford grid by Jimmy Collins and Stan Collier on 5 March 1966…

The race is the ‘Launceston Examiner Trophy’, the preliminary Longford Tasman round race, Jackie is being moved onto ‘pole’.

Stewart won the main race, the ‘South Pacific Trophy’ on the Monday from his teammate Graham Hill and Jack’s Brabham BT19 Repco- the new Repco ‘620 Series’ V8, 2.5 litres in Tasman spec, having its third race and gearing up for his successful world championship assault that year.

For the BRM boys it would be a more character building F1 year, mind you, Jackie took a great Monaco GP win in his nimble 2.1 litre P261 against the new 3 litre GP cars that May.

Stewart glides his BRM into Mountford Corner. Note the crossflow ‘inlet between the Vee’ spec of this P60 engine- the more ‘typical’ engine had the exhausts within the Vee(oldracephotos.com.au/DKeep)

In terms of the 1966 Tasman Series it was a BRM rout.

The 1930cc P60 versions of the 1.5 litre P56 V8 engined cars won seven of the eight rounds- JYS took four victories and the title (Wigram, Teretonga, Sandown, Longford) Graham Hill two (NZ GP Pukekohe, AGP Lakeside) and Richard Attwood one (Levin). Jim Clark won the other round, the ‘Warwick Farm 100’ in his Climax FPF engined Lotus 39.

The days of a Coventry Climax FPF winning the Tasman were over- from 1966 to 1970 the 2.5 Tasman Series was dominated by ‘multi-cylinder’ V6 and V8 engines of F1 and F2 extraction.

Lindsay Ross of oldracephotos captured the feeling at the time, ‘After his win at Longford in 1966 a lot of Tasmanians were now aware of Jackie Stewart and i, along with no doubt many other enthusiasts, began following his career.’

‘The podium shot has him shaking hands with Tasmanian Premier ‘Electric’ Eric Reece- he was the driving force behind Hydro-Electric power in the state. He also made sure the Longford roads were laid with the finest hot mix bitumen available. Ron MacKinnon of the Longford Motor Racing Association has the microphones- he owned much of the land around the Longford track.’

Brabham accelerates away from Mountford in BT19, surely the most photographed single-seater in 1966- Brabham’s weapon in Tasman and GP competition pretty much all year.

Note the long inlet trumpets of the ‘RB620 Series’ 2.5 litre V8. Longford was the new RB620’s third race- a 3 litre unit was used in the non-championship South African GP at Kyalami, and another of 2.5 litres in capacity for the Sandown International in Melbourne the week prior to Longford. All three events in BT19- BT19-1 still owned by Repco.

The next group of shots are all on the exit of Mountford- the corner onto the straight past the pits, here Clark’s Lotus 39 FPF from Hill’s BRM.

The BRM’s solo are #2 Hill and #3 Stewart.

And another podium shot from a slightly different angle.

Tailpiece: Stewart, BRM, The Viaduct…

Stewart wheels his BRM into the left-hander under the famous Longford Railway Viaduct- a tricky, fast on approach, downhill corner with minimal run-off area should the pilot goof. Note the spectators on the hill and alongside the railway line at the top.

Finito…
