Keith,
I guess you've never heard a race engine with a top end that sounded like a
sewing machine, ***becuse there was NOT enough oil getting to the valve
train***? Furthermore, there is ONLY one way for the valve springs to get
any cooling what-so-ever...that's with enough oil splash on the valve
springs to transport heat away to be transferred to the cooling system
through the block. Everyone who pushes oil restrictors completely forgets
the synergistic transfer of thermal energy inside the crankcase to the
cooling system of an engine and it's ramifications. Remember the old saying,
"beware of unintended consequences."

"I would NOT recommend the oil restrictors"
You know, I've seen this discussion before and I knew as soon as Bruce
mentioned it, there would be a flurry of "Don't use restrictors" I still
can't figure out why you guys are so dead set against these, because
Mondello recommends and sells them? I do agree that the return flow path
needs to be cleaned up so the oil flow back is better, but no matter what
you do, the gravity flow back can't keep up with the pump pushing it up.
After losing a few rod bearings right after I got my 67 442, I along with
everyone else figured out the problem was exactly that, too much oil up
top, not enough down below. So I went with a bigger pan, cross drilled
the crank and installed the restrictors. Would my problem have been fixed
by just using the bigger pan, I don't know, but I do know I can see no
negative effects from the oil restrictors and I twist the 400 to 7200
rpm's and all is still good 20 years later. Just my $.02.
