Does anyone know if a 2008 f150 4.6 has a cast block or aluminum block with aluminum heads? Do they have a stronger (more bolt.main) than the ones in the mustangs?

 

Iron block, 4 bolt main caps

 

and aluminun 2v heads

 

Same block as the stang. Same heads. Different intake and TB setup

 

In 04 the 4.6L Mustang was available 4v heads or 2v heads, 05-10 went to 3v heads, 11 ford dropped the 4.6L and went to the 5.0L

The F150 in 04 had 4.6L with 2v heads until 09 when it was available with 2v or 3v heads, and that lasted through 2010. In 2011 the F150 dropped the 4.6L for the 3.5GTDI Ecoboost
