OK, the temperature of
oil has been mentioned a couple of times. What is a good
oil temperature range? I have an
oil cooler, more for looks than performance, maybe I should by pass it.
I rebuilt a 289 hi po 271 HP many years ago. The factory rod bearings had holes in them, the new ones didn't. I drilled holes in the new bearings to match up with the holes in the rods. I ran the hell out of that engine for years afterwards with no problems. Those little holes certainly add lubrication to the cylinder walls and the cam & lifters.
