"I will have to bore it if I want to use it as piston 3 was stuck in it and left a shadow in it when removed."
not true..... learn to use a 3 stone hone and clean the wall. do not use a bead/ball style as this will and can give the cylinder oval shaped centre in the bore.
This will give you an idea of what I look for. but this is for higher performance build. I am too lazy to clean as Tony does so i send the block (s) to the shop to get hot tanked, (this process alone costs me average $450) to clean them up and install the new frost plugs and cam bearings. after i get it home i will start the final cleaning prepping and honing the block.
A 4L has thin walls so i won't bore it out.
proper honing ...
"In total it’s missing it’s intake, spark plug wires, distributor, ecu, and wiring."
I would seek out a pick-and-pull auto wrecker near you and make friends with someone there as you are going to need some major parts for this project. I would try and find a person near you wrecking a ford ranger that has/had a 4L in it as you are in need of tracking down stuff.
hope this information helps to guide you somehow. A 4L engine is not a V8 and trying to expect high performance tire roasting from it is an expensive road to travel down. know what you are wanting the engine/truck to do. what is your end goal?? know what you want to achieve ...
cheers
