4.9 efi replacement project
i bought a 94 f150 5 speed 2wd with the 4.9. i drove it home to find out that compression was reading 90psi. cosmetically it looks like it belongs in the junk yard but thats what i liked about it. this is the biggest vehicle ive owned and my first 4.9. so went on the interwebs and found a 95 4.9 complete engine and a few other parts for $300 and so the half-assed restore starts. i happen to know how to powder coat so im going to to paint some motor parts along the way. ive decided not to rebuild the motor due to my budget. my main goal is a reliable truck that looks ****ty on the outside and super clean in the engine bay. i live in florida so no emissions here, you know where im going with this. from the stock exhaust manifold im going to do true dual each to a muffler before a side exit. based on my reading no cats means the smog is pointless. i also believe the egr was already deleted, if that is whats on the back side of the intake manifold. so i have to figure out what vacuum lines are really necessary. also getting new motor mounts, trans mount, metal timing gears, fuel injectors( what lbs would be best? ) copper core plugs, cap and rotor, msd cut to size plug wires and an electric fan from a crown vic.
i still have alot to learn so if you have any questions comments or concerns please feel free let me know.

I can appreciate it, my '87 4.9 farm truck's previous owner was a professional alcoholic, not a straight panel on it, including the roof. Still, it only had 87000 on it, and it ran, and still runs very well. Has been in our care for about 20 years, got the bare minimum of care, and delivered better results than most of what I ever owned. Good luck with the project. May the beater truck Gods smile upon you and it.

looking at this post i cant help but wonder why you want a clean engine bay. me personally would just want it to run reliably. sure that 4.9 will last forever if well maintained, great idea on metal timing gears, that was my the final straw on my old truck. good luck with the build

Out of all the cars I've owned I've never had a clean engine bay and i kinda feel like its something to take pride in. Since I have the motor out what not try to clean it up a little. The motor in the truck now barely got me home so I guess that's my cue to start tearing apart the front clip. The timing gears was something I read about in the forums here but I'm still struggling to find a decent write up on the efi with minimum vacuum line and deleting egr/smog.
thank you for the support

Last night I took off the front clip and ordered most my parts. Need to make a second trip to the junkyard for more body parts.
as you can see in the photo that radiator support needs to be replaced.
