Yes, I only mention the other options in case you wanted to get rid of the secondary air injection.

Ok then, use the lower end of the 4.0, send the 4.6 heads to get done at the machine shop and use the rest of the components(SAI) from the existing engine already in the truck. I know I may have some issues like engine codes and such upon firing for the first time so I guess to invest in ABS/SRS/OBD2 scan tool. Thanks so much guys......
