Yes for sure on the checking. I was told by the local shop that its like 25-30 per rod to have them bushed. I just got off the phone with mancinni and they told me that diamond can do changes at 6 bucks per change to a point. So with using the 516907 piston, changing the bore to 4.290, and making the pin to 1.094 it would be 96 extra bucks per set of 8 so like 740 bucks for 8 pistons. Im good with that. Ill just polish the LY rods, and put my ARP bolts in them and be done with it. the LY is going to be fine for my application anyways. If I still had the tools at my disposal Id swedge some bushings in the rods myself and pin fit them myself, but Im way away from those tools anymore.
