It's cheaper to mod the six.

You could throw in a rebuilt T-bird SC supercharged 3.8L with little drama and cost (it was $1800 at O'Reilleys a couple of years ago), or get a race v6 with 400hp for $6000.

Swapping to an 8 requires a new tranny, (the six got the v8 tranny in 2001 - I think), new rear end, new front suspension, and you should replace the brakes. After that you've got the electronics, and the PATS which is a mess.

It's cheaper to buy a used v8, unless you're planning an all out show/strip vehicle, in which case the six chassis is a better one to start from, since the chassis hasn't had as much stress -you don't have to worry about cracks in the frame, the cracks in the rear suspension mounts, etc.

Also, the 302 is an easier swap than the 4.6L, cheaper, too-just an FYI.

Woe to him who builds his palace by unrighteousness,his upper rooms by injustice,making his countrymen work for nothing...Does it make you a king to have more and more cedar?Did not your father have food and drink?He did what was right and just,so all went well with him. He defended the cause of the poor and needy,and so all went well...But your eyes and your heart are set only on dishonest gain,on shedding innocent blood and on oppression and extortion.
