If I recall correctly the company was in for a bit of a let down with the testing of Black Shadow engines for the Picador project. Initial testing resulted in 48 bhp and many broken crankshafts, some in less than 20 minutes of running at revs in the high 5000 range.
They were looking for 60 continuous and eventually got it, new stronger crank design with bigger mainshafts, big interference fit crankpin ( nutless) and the famous Picador cams.
