O man you might have to go to another site for that one. PM Jadesville he'll give you a link to another site and they explain everything in the swap, from how long it took, to what they had to make themselve, etc... I know you have to change the K-member,computer, and wiring harness.

MM&FF had a guy do this. It was the issue with the orange blue flamed cobra on the cover. Might want to check into that as well.

I am going with the sohc , I think that the dohc engine would have been more of a project than I wanted to tackle . With the sohc the computer , and harness will stay the same with only minor mods . The upgrades I have already done will transfer over , TB. MA. ect . this would not have been the case with the dohc engine . I feel like the money I saved in parts for the dohc will buy me enough mods to get the same type of numbers out of the sohc .

i've seen them on karkraft.com and ebay; i believe most people who do the 5.4 swap do the 32v navigator as far as i know..

Are you planning on getting a Roots, or Twin Screw blower? I have that same article at home. If I remember correctly, the 5.4L Truck engines makes allot of low range TQ and not enough in the upper RPM Range. If I remember correctly Peak TQ occured below 2000 RPM. Are you going to use your 4.6L Intake Maniflod? If so, I believe the 4.6L Intake Manifold will smooth out the TQ curve allot.

I was interested in doing the same Swap. I will research my old magazines and post more acurate information.

If you can your cams wouldn't it help make the 5.4 at top end. I personally like cams mid to high. I don't like all the power at a low rpm.
