This post is just to satisfy my curiousity. But can anyone tell me what would be involced with replacing a 4.6L with a 351W? There will obviously be the two big areas, physical fitment and adaptation to the 4R70W; and then what to do about the PCM (so the CEL isn't on). If anyone can shed some light on this for me I would appreciate it.

TIA,
Steve

 

Yes it would be alot of work. Possibly more than it would be worth. Maybe look into dropping a supercharger on that 4.6 and you will probably have the same power. Putting in a 5.4 would still be alot of work but might be a slightly easier option. I'm sure some of the more knowledgable members can give you a better idea.

 

Its a great idea but way too much work involed to do it if you got the time tools and money to do go for it and let us know how it turns out.
