Tom,
Have you read the
May 1955 HRM article about Frank McGurk\'s 261 build ? It is about a 261, but Racer Brown discusses McGurk's camshafts, which were probably developed for 235s. I may have some more literature at home. If I can find it, I will put it on the BB. I have a McGurk 56 cam in my 261. I also have a Racer Brown cam that I will soon be running in another 261 that I am building.
