A.R.E.'s Tony Acerrio and Reuben Allen check the fitment of Racecraft's aluminum midplate on the back of our Boss engine. Like the engine plate, the 28-inch midplate also measures inch in thickness and is cut from 6061-T6 aluminum. The midplate eliminates the need for a block-protector plate with our McLeod scattershield. "Prior to working with the Boss 340 project, we didn't offer midplates for Mustang installations that use the regular steel bellhousings (e.g., McLeod, Lakewood) used by NMRA and other sportsman-level Mustang racers. We've always had front plates for Fox Mustangs, but our stuff for the back of a small-block Ford was mainly built for use with Pro-style, titanium clutch cans (that do not have the same starter-mounting requirement of a street or NMRA-style 'Stang)," Racecraft's owner, Mark Wilkinson, says. "The design for Boss 340's midplate is now saved in our CNC database, and replicas can easily be cut for anybody who needs one for a similar build."
