Some ?? about 318 build vs 360 build for my truck

Thanks guys. The 360 is rebuilt, has been pulled apart since its been sitting since 1990. the assembly lube is dried up and sticky, so everything needs to be cleaned. but all of it is new.
the 318 is basically new now. engine only had 40,000 on it when I went through the lower end.

Found out the tag on the dif said 3.55 gears, but counting the teeth on the ring and pinion it look like it has 3.26 gears?
