[Fot] Re TR4 camshafts

[patrickmannion1 at netzero.com]

Hello all,
I have always nearly always built Triumph TR4 engines with cams from Dema Elgin Superlobes in Santa Rosa. Occasionally I had installed other cams supplied by customers that had a valid timing card supplied. I decided with the English pound being low vs the Dollar I would try the PH1 Cam from Newman Cams in England. I had heard good things about their PH1 cam as being a great street cam.

When installing the cam. Information on there website stated peak cam lift was .295" (it is only .220") resulting in a lift at the valve being .120" less than stated. Starting off with" incorrect lift figure all valve event figures on the website are wrong. After several emails I got a two sentence email saying ,set Intake for max lift at 110 degrees ATDC and the cam will work, 

After doing lots of engine modifications I would like a more scientific answer than the cam will work. Has anyone used this cam or a Newman cam before, or found that the information supplied by Newman was incorrect. I hate to eat the cost of the camshafts I bought or incur the cost of sending them back to England, but I would have no confidence in using a camshaft without having a correct timing card for the camshaft. -
thanks
