4.5L to 4.9L engine swap...
- How much is involved in replacing my 1990 4.5L with the 1991 or later
4.9L for the same Seville application? Can you just replace the
engine? What is the difference in output of the two engines? What
year 4.9L would be best for this project?
I'm also interested in upgrading the brake rotors, calipers, pads,
