Thanks for all your answers. I am new to this engine and just wondered what external parts could cross to the truck. Once again, thanks for the feedback.

Stock for stock even the GT engine has more torque than the truck engine at the same rpm....

Truck
360 hp @5500 rpm
380 Tq @4250 rpm

Mustang
412 hp @6500 rpm
390 Tq @4250 rpm

Well then maybe you can explain why the engines are different. Must be some reason Ford built them differently.

Towing durability from what Ford has stated and what is done...Lower compression, Lower ignition timing, Different intake cam (truck doesn't need to have power to 6500 rpm), same exhaust cam (ford uses the exhaust cams for torque values mainly), Different TIVCT cam timing (even less power output for the truck), Oil cooler on the truck for towing (not on the mustang), Cast manifolds on the truck for towing durability(thin manifolds on the mustang) Same heads, with same size intake valves for both car and truck, Different pistons (Higher compression for the car, lower compression for the truck)...Those are the main differences off the top of my head.

So it's basically exactly what I said to begin with, the Mustang was made to build speed fast and the truck down low for towing etc....

Imagine that.

You also said the mustang engine wouldn't work good in the truck...but it will.

2 identical trucks side by side pulling the same trailer with the same load.

1 has it's intended engine the other has a car engine.

The truck with the intended engine will out perform the other, do you disagree?

Which engine will also last longer?

Yes, I disagree that the truck engine will out perform the car engine in the truck body. Now on the durability, I believe the truck engine has the car engine beat in the truck body.

Sharper than you obviously. There are quiet a few trucks out there with the mustang 5.0 because it is built for more power.

Disagree, the mustang engine makes more torque and makes it over a broader rpm range so it would certainly be faster. Which would last longer all depends on how it's driven and if you keep certain things like the oil cooler (and note that the 13' plus mustang do NOT have piston oil coolers like the truck continued to have). The engine that makes less power would usually last longer.

Also, the oils pumps are different, the truck has a weaker pump.h

Maybe I should stop trying to apply 20-30 y/o technology with current.
