Do I have the 4.6L 2V or 3V?

I recently purchased this truck with 260K miles on it and it seems to run fine. Since it has such high mileage, I'd like to be ready to replace the motor if the unthinkable happens. For some reason, I thought it was a 2V. Can anyone tell by looking? It seems like it has very high runners for all the pictures I've seen of 2V's.

From Wikipedia:
The 3-valve SOHC 4.6 L with variable camshaft timing (VCT) first appeared in the redesigned 2005 Ford Mustang.

And if it was a 32-valve then it would say 'Intech"

The 3v came with "aluminium" valve covers thats a dead give away the 4.6 3v didnt come to the picture till 2009 in the F150. The Intech engines only came in the Licoln model trucks/SUV and they were 5.4 32v engines and they really have wide valve covers.

2v looks just like mine. The long runners on the intake are to increase bottom end torque on the 4.6.

It says triton on the TB cover, telling me it's a 3v. Thats all I know of the 2v and 3v

the 4.6 4v only came in cobra and mach1 mustangs through 04 and Lincoln mark 8s. The valve covers are about 10" wide, and have a center plate that removes for coil and plug access, which are oriented just like an old hemi.

The 4.6 4V also came in 03-04 Mercury Marauder and 03-05 Lincoln Aviator.

that's funny because I was talking about the 03 and 04 marauder the other day. Forgot they had the 4v. Never seen an aviator.

Mach1 got a special R-code 4v.

The Modular engine sold in Ford trucks was called Triton from 1997 - 2010. The first truck usage of the 3-valve 4.6 was in the 2008 model year. So for three model years the 4.6 Triton was a 3-valve. For 11 model years the 4.6 Triton was a 2-valve. The name picked by the marketing folks was just a name. The 5.4 2-valve was produced for replacing the 351W in F-series in the 1997 model year and in 2004 the 3-valve 5.4 went into the F series.

As a result you can find F-series trucks with 4.6 2-valve and 3-valve varieties, as well as 5.4 2-valve and 3-valve varieties.

I, too, was disappointed to find my 2007 4.6 Triton was a 2- valve engine. But the only real disadvantage is I have to go slower pulling loads up mountain grades.
