ok im new and didnt see a search button or anything. my question is what frames would a 50 for F-3 fit on with minimal fab work. and could someone direct me to a good place for parts

 

There is seldom "minimal fab" involved when frame swapping. What do you hope to accomplish and how talented are you for starters?

 

What is the purpose of using a newer frame instead of upgrading the current frame ?

 

well one reason is avaliablity of parts and after market. i would think that lets say if it could go on a newer F 150 or a F 100 frame id have more options on what i wanted to do . and im mroe talented in some things than others like i can put things on and weld and motor work and my dad whos a body man can help me with what i cant do

 

The 50 F-3 is a pretty long truck with a wheelbase of 122 inches. Even if you find a modern frame that it will fit, chances are you may have to lengthen the donor frame some or shorten the F-3. I have a friend who has a 48 F-1 mounted on a 72 F-250 frame with the 360 engine and C6. He bought it that so way, so I have no details. It's is a daily driver and he even pulls a travel trailer with it, so it can be done.
