273 Commandos - What's your oil pres. reading? Difference hipo vs. stock distributor?

273 Commandos - What's your oil pressure reading @ idle, cruising & WOT? Is worth swapping to MOPAR hipo distributor vs. stock elctronic distributor ?
1.) I know it will vary depending on type of oil and mods so state what you've done to your 273 and what's the oil press. # Currently mine is between 37.5 to 40..273 Com. .515/.525 cam / 650 Holley double pumper.
2.) I'm shifting at 6000rpm on new stock electronic distributor (for 318 '70 Challenger). Any measurable power gains or RPM gains going to a MOPAR high perfromance distributor?

Looking forward to your insight fellas...thanks
