Ford 5.0L H.O. EFI SysteMAX Engine Kit
Must use Holley 241–81 valve covers, NOS Big Shot, Plate kit or a phenolic spacer for proper manifold to valve cover clearance. One of the Holley engineering test Mustangs used a stock Ford AOD transmission that was modified with a B & M 2500 RPM stall speed torque converter and shift kit. The combination provided very good performance results.
