: Basic 302 engine assembly photos

07-09-2010, 08:34 PM
I bought my bronco from a guy I work with a few months ago and the engine was rather stripped down when I got it. He was trying to fix some issues and only made it worse. Long story short I had to pull the motor and tear it down completely for a rebuild. It is in the machine shop as I type this and should be done early next week. Now the problem is that the majority of the engines sensors, harnesses, fuel injection, and emissions equipment was already off the motor and in the bed when I bought it. So yeah I dont know where everything goes and its been forever since I saw my old bronco with its fully assembled 302.. (btw my bronco is an 89). So if anyone has any photos of their own engine assembly and or their fuel injection system and emissions I would appreciate you posting them or even just a like to where you have them hosted online.
