In what model year did Ford switch to the 3-valve V-10? And can I assume the same model years for both SD trucks and the Excursions?

Thanks for any help guys.

 

2005, and I am not sure the Excursion ever got the 3valve v10.

 

Purdy sure it was the 2v with the 4R100 in the '05 ex.

Thanks guys. Appreciate it. I have found an '05 Excursion with 19k miles. I am thinking about selling my KR 150 and buying the Exc. I could use the extra beef to pull my travel trailer. I drive a company vehicle back and forth to work now so the gas mileage is not a big deal. I will only put about 4-5 k a year on it.

 

Other than the obvious, what's the real world difference between a 2 and 3 valve engine? In other words, could someone drive a 2 and 3 valve engine back-to-back and notice any difference?

 

the 3 valve motors move the peak tq band up higher in the rpms-phil

 

yes, you can tell the difference..
