4.2 to 5.8 swap
Hello everyone. I'm new to the forum and could use some input. I have a 1998 F150 with the 4.2 v6. She set for about a year, then I loaned her to a friend of mine, who blew the motor. I wasn't too upset cause she had about 230K miles on her. I've read that a 5.8 will bolt up to my transmission, but I wanted to know for sure what years 5.8 will work. The transmission is an automatic, I believe the 4R70W. Thanks for all the input.
