Title: oil pressure
Post by: onya on December 20, 2007, 07:47:37 PM

What's a good oil pressure for an 86, mine's on 75 lbs cold start, using 10w/40 fully synthetic.

I think that's about right.  Rule of thumb is 10lb for every 1000rpm - C4's run a bit more pressure though.

More important is what the hot idle pressure is?

"C4's run a bit more pressure though."
Why?
 Only has std volume / std pressure SBC pump.
