I am putting a new 460 in my truck and wanting to make sure I do it right. I am taking the intake manifld off to get it clean but am having a hard time getting the fuel in jectors out of the manifold. How are they suppose to be taken out. Also is there anything else that I should consider while putting this new engine in my truck?

 

Try some PB blaster [or penetrating oil of some kind] and also twisting the injectors as you are pulling them out. You can also try a gentle back and forth rocking motion.

As for other things to consider, what are you wanting to know specifically? There's a lot of different things you have to take into account.

Is the 460 you are installing out of a newer or older model truck?
Are you making any modifications that need to be considered when doing the engine wiring?

There's other questions to ask, but unfortunately that's all I have for now.

 

Thanks for.your help. I.am putting a new rebuilt 460 long block from a crate into my truck that now has a 460 in it. I assume it will just go in like the old one came out, i guess what i am asking besides the injectors is there anything else i can do to make the engine last longer,and how do i break it in. The body is in good shape so i do not want to go through this again.

 

I don't know for certain, so I'm really hoping someone more knowledgeable than I steps forward, but there is most likely going to be some wiring issues to be dealt with. By that, I mean that you MIGHT have to buy a different computer for your truck, or you may have to swap the engine wiring harness from your old engine onto the new one. Unfortunately this isn't something I know enough about to give you any specific answers. Try doing a forum search.

Breaking in the engine: Start off with cheap oil for about the first 100 miles. You've probably put enough money into this project as it is, there's no sense in putting expensive oil into the motor until you know for sure that there won't be any problems right off the bat. Just buy the "bottom of the barrel" brand oil you can find and run that for the first 100 miles. After that, feel free to use whatever oil you want.

The engine won't break in till the 500-700 mile mark depending on how you drive, but otherwise there shouldn't be anything else you need to do. It wouldn't hurt, however, to double check the torque on some of the nuts and bolts such as: [after the break in period]

Rocker arms
Intake manifold [upper and lower, if so equipped]
Exhaust manifolds
Transmission to engine bolts

As for helping the engine last longer, it all depends on how you drive it and how well you maintain it. Some people get far too caught up in Ford vs. Chevy vs. Dodge vs. any other make; for me, they all have their faults whether its a design flaw or a simple recall issue. My point is that as long as you take care of the engine, it's going to last. Many people would be surprised how much longer their cars will last if they would just bother to do the basic maintenance instead of ignoring it to the point of becoming a real problem.

I hope someone else can answer your questions. Good luck.

 

Crate engine? I would expect the rebuilder to include break-in instructions, these sometimes use high-zinc oil for the initial break-in. In any event, follow the rebuilder's instructions precisely.

 

swap over to new long block, intake, sensors, dizzy, pumps on front of engine, exhaust manifolds and you can leave the injectors in manifold. There shouldnt be any wiring problems other then remembering where everything went when you pulled it apart, take lotsa pics as you dis-assemble.
