Just curious the scat cranks that we are using use Chevy bearings for the rods. Do they also use Chevy bearings for the mains. And when you get a new crank does it go in standard or are they cut .010 from the get go. Of course I wouldnt order anything till I take it apart but just wanted to ask ahead of time. So the reason Im asking is I have about 1500 street miles and a ballpark 60 1/8 mile passes and about 50 1/4 miles passes. No over revving or anything but as you guys know when I went of the track although I didnt see any dirt in intake when I took off carbs some dust could have been sucked in and im sort of looking to nip it in the bud so to speak. Any opinions.
