Re: Difference between a 4.8 and 5.3 ls engine

Just like your block has 6.0 casted into it. The 4.8 and 5.3 use the same block so both numbers are casted by each other (4.8/5.3). Unfortunatley I didn't take good photos of the green paint which seems to cover the casting number. It wasn't until I was looking back at old photos that I noticed the green paint.

I got to thinking maybe that spot of green paint was covering the 4.8 which was an external way of signifying I have a 4.8 engine.
