I was under the impression from when I was at Don Allen that the first oil change was on GM, at 7500 miles… something about flushing out an additive they used? maybe i’m remembering wrong, but still unless it had been sitting for a year, or some long amount of time why change it with only 150 mi?

most new ls1 motors have a zinc addative in the oil not sure whatfor but when steve (ultra Z) built his 408 he had to but like 12 a bottle quart oil that had a zinc addative for the break in period
