Starting the V10 swap in 99 F-150
I already have dual electric fans. I know it sounds funny, but I use an OEM setup from a V6 Maxima. They are dual speed and I just run them at max anytime the engine is running. Never had a heating issue even off roading in 100+ temps. You can get them new off ebay for like $50 and they work better than more expensive setups I have purchased.
I just wasn't feeling it today... I didn't get much done this evening.
The engine is bolted in, and there are two transmission bolts in. I don't think those spacers I made were necessary. (EDIT: Maybe those spacers were required after all. The A/C compressor is very close to the idler arm bracket and I'm sure the extra height helps) I only have about 1/8th inch of clearance between the top of the IAC and the sheet metal of the cab. I ended up leaving the driver's side mount in the same orientation as it was on the 5.4 and then on the passenger side, I flipped the mount upside down.
The exhaust does NOT line up, so plan on some fab work there. Drop the Y pipe before you start to drop the motor in. It WILL get in the way, and you have to modify it anyway.

Oh yeah, totally agree. The intake isn't bolted on right now, so I will BFH the sheet metal before its permanent.
EDIT: Nope... Flipping doesn't work. There isn't enough clearance for the linkage to rotate.
19 lb. Apparently the same as the 5.4 which makes sense since the bore and stroke are the same. I had to go look at my old engine to see if it had orange top injectors. I didn't remember them being that way.

So far, I highly recommend them. Vern was very knowledgable and when I told him what I was doing, he said he'd make sure to give me everything he thought I needed to complete the project. He was very professional and spent a lot of time on the phone with me.
Screw the BFH. Get a 2 or 3 inch body lift. That will solve the problem of not enough clearance. Can't wait to start on his summer on this. Hopefully by next fall it will be up and running. Planning on taking the cab off as I would like to clean and paint/undercoat everything to protect it from the lovely road salt here in Wisconsin.
I woke up at 2:00 AM with a headache that just won't quit. I toyed with doing some wiring, but made no progress beyond planning.
I took part of the V8 harness and part of the F250 engine compartment harness and I plan to combine them to make an "intermediate" harness for extending the V10 engine harness to the F150 engine compartment harness.
EDIT: This was a bad idea. Pic removed.

So the intermediate harness idea sucked. Many of the wires didn't match up so I started moving pins and stealing pins from the V10 body harness and then I realized that meant I couldn't rely on the V8 ECU pinouts matching up with the V10 harness. Duh...
So, back to the V8 harness - I had two so my original is still intact. I bolted down the intake and installed the coils then started to see how things looked and ran into another snag. The fuel injector plugs on the V8 are different than the V10. I have snipped all the injector connectors off the V10 harness to solder to the V8 harness.
I have also done little stuff like install the starter, torque converter nuts, (glad I remembered to swap my 4 hole flexplate from the V8) transmission to engine bolts, oil change, transmission fluid change, throttle body cleaning, and front accessories.
The A/C compressor is very close to the idler arm bracket, but I think it will be OK. ***EDIT: It's not OK!*** Same thing for the IAC after some bashing.


I made a spreadsheet of what pins I'll need to move around at the ECU to work with the V8 harness. It took some thinking because COP 1 on the V8 harness is no longer COP 1 when used on the V10. I made a little illustration to help me keep things straight. I'll update the pic below as the project progresses if changes are made.

Thanks. There have been several times where I caught myself just staring at the engine compartment thinking I'm in over my head.
I still have some mechanical hurdles too. The dipstick for the tranny won't go in. I don't know if I bent it or if it's the different exhaust manifolds or what. I haven't even started to think about the cruise control cable or vacuum lines. Then there's PATS... It also must pass smog.
I really miss driving this thing and my kid is missing out on dirt bike season!

It's alive! Barely, but it's alive... I put it together just enough to get it to run so I could hear it. From the 5 seconds or so I let it run, it sounds like I have the injectors and coils right. I can't tell you how sick of soldering I am right now.
It's running straight out of the manifolds, there are lots of vacuum lines not connected, wiring is still ugly, front diff is still out (not related to V10 install), and the air intake goes to nowhere.
Pics and more info to follow. I haven't eaten in 9 hours, so it's chow time.
