I am looking for a 429 for a 1994 F700. 1)Does anyone know if these are different than the motors found in non-heavy duty trucks?

If so, can anyone help me locate a crate or rebuilt 429 for this truck? Thanks.

 

Your prior post has a source:

429s were never used in light duty trucks other than the Ranchero. The 429 in mediums like yours is different from that engine, and different from the PU/car 460s, making a direct swap impractical.

"Different" as in crank snout, mounting, accessory drives, bell, clutch, pilot hole in crank, along with the heads, intake, exhaust etc.

 

It can be done but not recomended. The 429 for trucks used a steel crank I believe as compared to a cast crank. They had calcium I believe in the heads also. One thing though is what will you be using the truck for?
