What all needs to be done to switch my 4.9 to a 5.0? My Truck is a 1996 f150 with the 4.9 liter and a five speed tranny and i found a 94 with the 5.0 in it.

 

If your 4.9 is running good, I wouldn't swap it, you really won't gain anything except for a better sounding exhaust.

If your needing to replace a damaged engine then go ahead with the swap. You will need alot of parts like the motor mounts, computer and wiring harness out of the donor truck. Since your truck is a 96, its OBD II, so I'm pretty sure you need a 96 5.0 computer since 95 back is OBD I. I think it will be more trouble than its worth.

 

Thanks but i need to do something cause its a new 4.9 in it and i can't get it to run

 

Sorry.. but if you're having trouble getting the existing motor running then a V8 motor swap into this truck is going to be WAY out of your league. Describe what problems you are having with the 4.9 and maybe we can help sort it out.

 

If you can't get the 4.9 to run, what makes you think you're going to be able to get the 5.0 to run?

I agree with Paul - fix the 4.9. What's wrong with it?

 

It starts and runs for awhile then dies

 

When it dies check for spark at the plugs & fuel at the fuel rail ...Lew

 

ok it should be getting spark cause i put a new distributer new ignition coil and new ignition mod in it plus new cap wires and plugs

 

then check and make sure the fuel pressure.

 

And "Should" and "does" are two different things, verify it has good spark when it quits just to be sure.

Wouldn't be the first time a "new" part was found to be defective. Odds are good its fine in that regard but until you check its still a question mark.

 

You really expect anybody to be able to help you when you describe the problem like this?

The more details you give us the more we will be able to help you.
