351 swap in a 88 cougar Reply #3 – June 03, 2006, 12:04:38 AM You will have to swap over to Mass Air, if not already. Then you will have to have chip burned to let the computer know the displacment change. The price of the 351 swap headers is alot. All I did was use stang unequal lenght shorty headers. I had to buy a steering shaft kit from Flaming rivers to get it off of the header to pipe ball . Just a little insight from someone who has don it. Quote Selected
