It does look like a works competition engine build though and an 8 port at that.

Apparently an S was £921 in 1968! This is an astonishing amount of money relative to the cost of the car!

Still, no VAT in those days.

Might have been a 970 or 1071 though. I think my 970 was around the 115hp mark with Arden head in the late 60's early 70's.

Take note power lost getting to the rollers is 22/24 bhp and that's with a full set S/C gears.

Even taking into account engine development over the years some BHP figures do seem optimistic.

Rolling roads figures do vary a lot but they are great for when you are talking in the pub or on forums.

Isn't there a press review of an ??? 777 F works demonstrator with an 8 port head? It was the ST hack during the late 60's. I am sure I have seen one in CCC.

On a separate note, actual dyno figures are meaningless, just look at the results that Downton were obtaining throughout most of the 60's. To say "Those figures look disappointing" fails to take into account the 1000's of Club, National & International wins that Downton engines contributed to. They may not have been great fans of Bullshit BHP figures, but as a wise man once said. . . . . .

£522 was a bit. I wonder what it would have been to add the bottom half of the engine and a gear box to that?

In the same time period Richard Miles (Downton, London), offered what they considered a new full race spec Group 2 engine and gear box for £650. Not an 8 port.

A new standard Cooper 'S' engine and gearbox unit from BMC was £235.

Fitzpatrick is the test driver on the invoice but doesn't remember the job, though does say he was very friendly with the Richmonds and that he may have done a quick test whilst in Wiltshire. There's two more similar invoices I've sent to Mark for the website courtesy of Nick Wardley. I agree with Mark, most likely a rally engine.

Certainly clever, wise at times is debateable.

Rally car engine in Feb 68, seems very doubtful. Will Sparrow was noted for running an 8 port rally car and iirc that was 69?, but definitely 70. More than likely at that time a british saloon car championship private entrantor rich club competitor.

You really have to take Dyno figures with a pinch of salt. They seam to vary by as much as 10bhp for every 100bhp from engine builder to engine builder. Downtons 100bhp could be 110bhp on Joe blogs Dyno today. It's not a fair comparison.

The one I am thinking of was a press demonstrator, not a pure competition car, this would also explain the customer details on the invoice.

C&CC did test ORX 7F Mark, one of the JBLs , though I think they were a 5 port, but also OBL 45F much later.

Cosworth HPs were always thought to be better fed than most.

If this is the same family, the Startin's were long term coachbuilders.

The engine may have been for this car.
