BW,
Lot of interest in the cams, please put me on your list. Could you describe how the "S" cams might be different than the performance cams Hitchcocks advertises? If I can get a set of "yours" I'm wondering about other options.
Thanks Much,
Bill N.
Hi Bill - well I am taken aback by the interest shown this time round and I will try to see that everyone who wants a set gets one, but it may mean waiting for another batch and they are slow in coming, sadly. The 'S' cams were a fairly soft Redditch pattern from the late fifties. Basically, without repeating the whole story, I did the R&D work on an Electra X tuning package for Hitchcocks and many cam types were tested, some boosted power, but none gave an increase in RPM, due to a violent inlet valve bounce around 5,800 RPM. I had tried all the cams and timing combinations I thought might work, with no real luck, and then I spotted some old cams lying around - they didn't look very exciting, but just so I could say I had tried everything, I gave them a go. An hour earlier, I hit 87 MPH flat out in 5th [top] gear on this machine, with these old cams in it reached 95 MPH in 4th! Top gear and almost flat on the tank [in very heavy rain, with waterproof jacket, leggings etc], I hit 103 MPH, job done and the machine went back to Hitchcocks, with all my notes. I recommended the 'S' cams for the kit, but they already had something to offer, apparently, so these cams never made it into the kit. I took it upon myself to get some made and two batches sold out completely - this next will be the third - they also work well in the 'Classic' or 'Iron' engines and a couple of my 'Asbo' engines have them installed, although no two of these engines are identical.
I will try to make sure anyone who wants a set, gets them, but please bear with me, the makers take a long time and batches of 6 sets are all I really want to stick my neck on the line for at present.
Thanks to all for your interest and understanding.
B.W.
