Add me to the F-150 6cyl list. It's kind of a wash between the automatic and manual because the 5-speed they put in them wasn't that great, but you can get them converted to the old tried and true 4-speed manual. Also, the 302 isn't bad; not as torquey and a little worse on gas, but solid otherwise. The 4.2 V-6 is hardly worthy of being called a truck motor and the straight six will probably outlast it two to one. Personally I'm keeping my eyes open for a 94-96 6cyl to put in our van. After I turbocharge it. That may be a pipe dream, but if done right it would beat the pants off the 351W that's in it right now in both power and milage.
