I would not use scat rods as I have seen many issues with small end alignment and to rebush the small end = buy the better rod straight up( was sent 3 different sets once and none of them were rite )+ and most scats dont even come with ARP 2000 rod blots - just my 2 cents though - it has to be balanced due to different rod and piston weight to std - check out atomic rebuild kits - rod and piston combo can have a huge affect on your balance cost,if you have to put heavy metal in the crank it can get very expensive
