My last Ford F-150 company truck had the 4.6 in it, the 2011 I have now, I has the 3.7. Standard cab, 4x4 8' bed and I sure miss the 4.6. The 3.7 may have more HP, but no torque. Unless you drive it aggressively, it seems like a dog. Still, I just rolled over 108,000 and only had one problem with the charcoal filter. Of course, I bought my other F-150 with the 4.6, when they retired it and it has 183,000 and still running strong. we get employee pricing on our trucks, I am still not sure, If I ll buy this one or not.
