H oversize pistons and oil pressure

Posted by Zachary Hoyt on March 22, 2010 at 14:11:27 from (74.33.212.153):

I have two questions that I'm wondering about. I dropped the
pan on my H today to make a new gasket for it and noticed that
it has the 3/7-16" replacement pistons. I've seen the Nebraska
results for stock H and I'm wondering if anyone knows how
much difference there is in displacement and HP oversize vs
stock. Also when I've been working it lately and the engine gets
warm the oil pressure drops a lot. Cold it is about 3/4 of the
way over to the right of the gauge but warm it gets down near
the red line and it makes me nervous. I don't know what weight
of oil it had, but I'm thinking of putting in 15w40 which I've seen
recommended on here. Is there anything I should look at while I
have the pan down that might have to do with the oil pressure?
Thanks very much for any advice.
Zach
