[LS short box]

I've used Lokar on some of my LS swaps. See pic. You can just see the top of the dip stick is on the left side just below the coil cover. I use 2002 Camaro oil pans.2002 Corvette coil covers.
Another pic of a LS3 swap I used a stock LS3 Corvette dip stick using a 2002 Camaro pan. LS3 Corvette coil covers.
Best thing to do is put in 6? quarts in the pan and see how it reads on the stick and then mark the stick as needed.
