This pack brings classic Ford FE big-block engines to the 1967 Mustang, giving drivers the choice between the torque-heavy 390 FE and the race-bred 427 FE Side-Oiler.

Alongside the engines, a complete drivetrain overhaul adds multiple classic Toploader 4-speed transmissions with different rear gear ratios for street, track, or highway cruising, as well as modern Tremec T-56 6-speed manuals for aggressive acceleration or sustained high-speed driving.

It's a solid pick for players who want more authentic powertrain variety and classic muscle car performance options for their Mustang build.
