I have Scat I-beams in my stroker, no oil squirt holes...I talked to my machinist before I built my motor because I was alarmed that these holes were missing, he informed me that over the years they discovered that they aren't needed. So I went ahead and built my motor...now 5 years later, with TONS of abuse, mid 10's in the 1/4, driven on the street weekly, no problems whatsoever. The Scat I-beams are a great rod for the price.
