Modular,SOHC?
Can someone explain what this means? This is what the vin# Letter L Is telling Me what My engine is I get the EFI part. Just not what the modular means and the SOHC means Is This a good engine?
I have been reading some of the posts and for the most part everybody likes the engine Some say a little under powered( I think for what I use My truck for there is more than enough) Maybe I am getting old.
Does anyone have an answer and or an opinion on this

"Modular" is the engine family name. SOHC means single overhead cam. Basically on an SOHC engine there is one came above the valves in each cylinder head. The modulars are good motors and with minimal maintinence can last a long time, well over 200k miles.

Ditto what dkf said. Plus, although the modular engines are lower on horsepower in some people's books, I feel they more than make up for that in torque and the actual torque curve itself. Having a high horsepower engine isn't always the most desireable quality in a truck. I had the 5.4 in a 1999 F-150 and it was a fantastic engine. It pulled very well and I loaded the truck and trailer full of mulch and pulled heavy on a regular basis. The truck always had plenty of power.

Ya know I had the over head cam part Just could not figure the s part. My taurus has dual over head cam. Boy do I feel dumb. Do I have the three valves I hear some people talk about the 3 valve engine.
Thanks for helping out on this. I am not use to such new vehicles My first 2 fords were 76 f100 and 78 f100 both 302 carborated engines.

From 1999 to 2004, the SD's have the 5.4L 2V engine. From 2005 to present, the SD's have the 5.4L 3V engine. Currently, there are a lot more aftermarket "goodies" for the 5.4L 2V engine!
