Mopar R3 Block
These are the best two pictures I pictures I could find real quick. The 48 degree block picture I pilfered from here on FABO. The other came from FBBO.
Here is the 48* LBA
Here is the 59* LBA
As you can see, the 59* LBA is laid towards the cylinder walls and the 48* LBA is stood up and moved towards the cam.
