TRANSMISSION STAND-ALONE CONTROLLERS & TPS ADAPTER KITS - ADD-TO-ORDER HERE KIT OVERVIEW This kit is for connecting a small block Chevy engine to any Ford Small Block or Modular (4R70, 6R80 & 10R80) automatic transmissions. By using this kit, you can easily swap out your existing Ford engine for a small block Chevy engine while retaining your original OEM driveline setup. This kit is ONLY compatible with 2-piece rear main seal internally balanced engines from 1955-85; such as the common classic 350ci This kit requires use of a 164-tooth neutral balanced small block Ford flexplate (Pioneer #FRA-317 or equivalent). Constructed from high-quality materials, the adapter plate is crafted from 6061 Billet aluminum and measures 1" thick. It is contoured to fit the engine and transmission interfaces as closely as possible, ensuring a seamless connection. The crank spacer/adapter is made from 1018 Steel, providing both strength and precision without compromising on durability. Efforts have been made to minimize the addition of rotating mass and keep the adapter's length as minimal as possible to prevent interference. The starter is mounted directly onto the adapter plate and is designed to snugly fit into the Small Block Ford (SBF) & Modular starter boss. However, depending on the specific transmission used, minor material removal may be necessary to ensure proper clearance. In summary, this kit offers a reliable and precise solution for mating a small block Chevy engine to a Modular or Ford Small Block automatic transmission, allowing for a smooth engine swap while maintaining the integrity of your original driveline setup.
