I like the roller bearing idea and might see about that in a future
rebuild. For now, the trick I used seems to work just fine.<br>

I didn't use the hipo part. My engine builder tried to
find a solid eccentric but none were available. He
ended making a new 0.090" base and welding it to the
eccentric base. Asa has posted his modification for
the eccentric: <a href="http://www.asajay.com/351rebuild/eccentric.htm" target="_blank">http://www.asajay.com/351rebuild/eccentric.htm</a></span></div>

<div><span>I've been running

years and couldn't be more

<div><span>I don't know what
the spring pressure they
use and how it compares to
the stock pump but seems
to be a bit stronger.
This could lead to the
eccentric drive on the cam
gear. I had the cam drive
pin fail earlier in the
year. The base of the
eccentric was bowed a bit.
The end result was that
the drive pin failed and
some carnage in the
engine (2 broken valves).
Fortunately the block was
ok and the heads needed 2
new valve seats. </span></div>
