5.4L Head swap???

rwk3072 · July 19th, 2006, 02:31 AM

Interesting site I have found here... Trying to figure out if I just wasted a bunch of money on E-Bay... Found a set of heads off an 02' Lighting (5.4L Supercharged) hoping they will work on my 97 GT (bone stock). Any Tech experts out there whom may know the answer, and also if I should be swapping the Cams out when I make the switch from Supercharged to not? Lastly, this swap all started with that damn plastic intake cracking, (why not get some PI heads at the same time), so what Intake would I use with these Heads, assuming they will work at all? I was kinda assuming if the heads would work, then the intake for a GT should also work.

Ford had a good idea when they decided to use a MOD motor platform.... 4.6/5.4 are the same

Aside from bore/stroke... they are interchangable. So go ahead and put them bad boys on youre car. Not EXACTLY sure on the s/c specs on the cams, but i would just leave them in there.... unless you have a Stage cam you want to put in there.

All of the cams are the same also.

uh i didn't think the heads are interchangable but i guess i was wrong. but you can use the pi intake with an adapter that just came out from a company i can't remember its name, its in the new 5.0 mag.

White... what adapter. I have the 5.0 with the Shelby on it.... just checked and didnt see anything ?

how much are 5.4 heads going for? you think its worth it or is it better to just buy some aftermarket patriot heads or afr's or whatever?

i was readin my new 5.0 mag today and found these new conversion plates. they let you use the 4.6 intake on the 5.4 heads so you can out the 5.4 heads on. they are at www.reichardracing.com
