I have a "new" Gen2 hemi in my 66 Hemi Coronet W023 clone. World block, Edelbrock heads and intake and carb. 10.3:1 and dynoed at 488 at 5450. Engine probably has <1000 miles on it when I bought the car, <1500 now. First oil change on my watch. Oil recommendations? Old standard 10W-40, or one of the new 0W-20 synthetics?
