Ultimate customs actually makes a kit to do this swap. I've been looking into it myself.

-Ultimate Customs Metal Craft offers three kits for this series of truck. V8 305-350 (Chevy), V8 302 (Ford), V6 4.3 (Chevy).
-Each Kit has been engineered for the easiest install possible. All kits are based on OEM parts and makes searching for additional parts a snap.
-Instructions for each kit is complete with part numbers and pictures for all steps, including wiring, plumbing, Speedo cables and rad.
-Our V6 kit uses everything available from GM including a fan
-Our V8 kits use G.M./Ford parts, but you are required to purchase some after market parts.
Example: 305/350Chevy and 302 Ford Kit
Short water pump - 14" or two 10" fans -Rad Modification
-As for transmissions, Due to the factory high gear ratio of the Mazda truck, an overdrive transmission recommended for the 305/350 kit. A TH 350/200 R4 and the 700R4 can be used.
