To the Lists -
I am replacing a camshaft in a '73 TR-6 which had two lobes extremely worn and
one lobe nearly gone. Disappointing since this cam has only about 10,000 miles
of use. The cam lobes that were still good looking had a lift of about 0.240"
but it is now history. I purchased a new camshaft from TRF, part # 307621/GP,
which is described as a new, chilled iron, stock cam. I am not looking for any
performance upgrades that would require re-working of the head or other
components. Before installing the new cam, I dial-indicated the lifts for each
lobe and was surprised that they are only 0.213". Is this the actual
specification for a stock cam? I did look at the results of a survey that Ray
Hatfield send out in October but felt that most cam upgrades would result in a
power band at a higher rpm than I'm looking for, hence the stock TRF item. Any
suggestions?
