Mayf:
good point about the low oil pressure kill switch. Don't think I ever knew
a modern-era drag racer that didn't have one.
As you probably know, we can't get pictures directly on our "list". That's
why I didn't include the graph in the original discussion. I'm leaving for
a job in a few minutes, but I'll scan-in the graph and send it to you in a
day or so. JPG O.K.?

Russ, there are switches for automatic shutdown of the engine if there is a
loss of oil pressure. I had one on my drag boat. SImple to wire into the
coil loop:circuit is closed with pressure, opens at something above zero
(like maybe 10 or 20 psi). As to not fusing, yeah I agree but burnig down
the harness has exactly the same effect of blowing the fuse: disaster. Oh, I
never saw the "little" graph, can you send it directly to me?
