Dave,

Tell me, what would you consider the safe (prolonged, say one hour) cruising speed to run a 1930 Std 8 with stock gears? Lets assume the engine is in good condition. I feel comfortable at 50mph but anything over 55 just seems like it's too much.

Not to hijack the thread too badly, I have chosen to run Rotella SF rated 15W-40 in my 726. I have 35 or 40 lbs of pressure going down the road at speed.
