Yikes!   I  have always had great success with Dema's cams.
I hope his shop survived the fires.

Subject: [Fot] Re TR4 camshafts

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
