when you purchase a new motor does it come with everything needed to run
the car or do you have to buy other items like the water pump or headers or
any other things that are not the actual block. also, does the wiering kit
and new ecu (i guesse thats what i need) usually come with the engine.
You usually have three options when purchasing an engine.
1. short block (comes with rotating assembly) no cylinder heads or valvetrain
2. Long Block Everything except accessories,sometimes no harness
3. Complete motor (powersteering pump,etc)
