Would like to see a 302 conversion "kit"
I only drove the car about 2-3 miles, close by the shop in Livonia where the conversion was done. Everything necessary to do that drive worked just fine. And if you don't live in Metro Detroit, as I do, the whole idea of engineering may exist in a fog of uncertainty. But be well aware that if you have been around the Ford end of the car business as is common to living here, it's not too hard to find the people who did the original work in designing a particular component.
When I met the lead engineer for the LS-type ECU design team, he was involved in doing the tuning on a blown (aftermarket components) F-150 at a dyno facility in one of the downriver suburbs of Detroit. He'd not formally left Ford, but was on his way, and he told me several weeks later that he'd accepted a position with a very-well-known race shop here in town.
I'm sure you don't mean to suggest that having designed the electronics in the first place, he'd be unable to make any changes necessary to make the system amenable to adaptation and improvement.
You simply have to have access to the right people. And don't try to make all the changes in the day or two before setting out on a 'Cannonball'.
And as a side note:
As I've noted on this forum in previous discussions, the ECU doesn't know exactly what sort of engine it's attached to. In order to work properly, it's only necessary to have the sensors attached to the engine be of such specification that they communicate properly with the ECU.

Hi, I have been following this post for a long time and saw 2 videos on youtube of this car. I think this car is a terrific car and I have one myself, that blew a head-gasket. (The ignition coils many times misfired and were replaced, and are a known problem with this car. Over time,(several years) it caused the catalytic converter to get clogged up and create back-pressure and heat, that, at the later stage of the game, caused the excessive overheating blow a head-gasket.) I saw many threads of putting the 4.6 DOHC engine in this car, a civilian to do it, not a Ford Factory team, and it seems mostly talk, with only 1 car shown as a conversion example. I've read that the 3 Valve 4.6 is a possibly easier conversion. To me, it's all mostly talk until I see it really happen by enthusiasts really doing it. I think the approach you took, to put the 6" to 7" less wide 302 which has same weight, or less, and has better physical dimensions, is actually the far easier conversion given the tight engine bay of the Lincoln LS. I think, from a cost point of view, it's a more cost effective solution for guys like me, that have a blown engine, where the cost of machine shop work on this aluminum Jag derived engine is not worth it, or getting a junkyard engine is not worth it, since you still have no after market support for the Jag derived 3.9L.
I respectfully ask that after you put all the engineering work to get this test mule (your own car) working, that a kit could be put together and sold. Everything from mounting brackets, any custom (if needed) pulley brackets, the A/C hard lines and steering lines, or anything else you've fabricated and most importantly of all, the PCM work, and any after market additional components to control the fan and fan relays. I also think that perhaps two kits: one where the owner keeps the original 5R55S (or is it 5R55N?) and simply needs the correct bell-housing to attach to the 302 engine, and one where the owner swaps in a manual, such as you did. If the original transmission is kept, it's not only a big cost savings, but also, it keeps the drive shaft in place without substitution, and keeps all the servos and anything that might affect traction control also in place.
I think if you were to put together a kit, that has everything in it: mounting brackets, Hard lines, additional electronics to adapt the existing PCU to the 302 and make the gauges and all the other electronics in the car work, and detailed instructions, I think you'd make a killing selling it. There's a ton of knowledge on the 302 and many 347 engine variants sold as well. The ability to convert a 11 or 12 year old car with a blown engine and work with the 302 instead is something that would be welcomed by many Lincoln LS8 owners and LS6 owners as well. Please let me and other here know your thoughts; especially since you have access to some of the original Ford engineers in Detroit that worked on this car, and us regular folks don't.
That is the type of pump that I was looking for first. I probably would have gone that route if I didn't own a Honda S2000 in the past. The power steering worked very well at different speeds.
