Packard53 is giving u some good advice on the oil. If i remember rite, u said in another post some weeks ago that u r running 20-50 oil. Thats TOO heavy unless u're SUSTAINING 140-180 mph in 100+ degree ambient for many hours on end. The Packard V8 runs in the neighborhood of 180-220 degrees which is relatively cool to average.
