Do 455 olds with Berkley jets have problems? I just spent the day with Stardust blowing thru 40 gallons of fuel with lots and lots of full throttle. No milk shake in my crankcase. Tell me why people are doing all kinds of "enginering" to control pressure thru the engine. I understand the theory behind too much pressure and gaskets and such, but my 1970 Olds. 455 with nothing added between the Berkley and the engine seems very happy. The temp. was always low...too low, like 86 F, so that concerns me. I would like to get the temp to normal....gate valve???? Normal temp. = better fuel economy...right? I need to get a pressure guage on the engine cooling system. I have read about low pressure causing hot spots in the engine. Maybe that would explain burnt exhaust valves in the past...I am looking at past machine work done on the engine.
What are your experiences?
