Hi guys i'm new here so not to sure how it works. My question is, i have 01 f150 4.6 xlt ext 2wd. need to know if i can replace my 01 4.6 with a 2001 5.4 and if there is alot of changes if any. would i have to switch trannys or computers. a quick answer would be great as i have a 5.4 lined up with only 50,000 kms on it as my 4.6 blew up yesterday, thank you
