Hi Bill,
<I'm considering a set from Denis Welch
because they claim increased cam lube and lighter running weight. are there
any better options?>
I run the Dennis Welch pushrods & lifters - no problems after 10 years.
Same principle as a Sprite/ MGB - bucket follower. Not sure of any other
options.
<I'm wondering if I am a victim of the legendary ZDDP famine or maybe too
infrequent oil changes or both.>
If you are concerned about ZDDP issues - have a look at Penrite oil.
See http://www.penriteoil.com.au/technical_bulletins.php and under engine
oil download the PDFs 137 and 149
I use Penrite HPR40 and have done for the past 14 years, it is still choc
full of Zinc goodness...
Best
Chris
