# UMI Performance 70-74 GM F-Body LS Swap/T56 Kit

UMI’s LS swap kit features engine mounts and a T56 crossmember used to place a new drivetrain in 1970-1974 GM F-Body cars. UMI’s LS engine mounts locate the LSx engine properly on the 1970-1974 crossmember. The mounts feature precision laser cut 3/16″ steel and a tough powder coat finish. Engine vibration is damped using the latest greaseable polyurethane bushing technology. Slotted design permits 1″ fore/aft movement while crankshaft height remains in stock location. The transmission crossmember is built using laser cut tab and slot construction and features 1.5″ adjustment range. The high strength 3/16″ steel crossmember adapts both T56 and T56 Magnum transmissions into the F-Body. Race proven on the UMI 1971 Camaro. 100% Made In USA.
