Complete Bolt-On AV8 Conversion Kit - Ford Model A to Flathead V8 Ford

$ 1,799.99


If you've tried installing a V8 in Model A, you probably now know that it is not a straight forward task. Traditionally this has required the use of later model pedals, mounts and crossmembers. Hunting these down is time consuming and expensive - if you can find originals. And if you don't have fabrication chops, this task got even more complicated. Unfortunately, most people find this out the hard way. 

Our Old Yankee Speed Co complete AV8 kit solves this common dilemma. This kit is designed with using stock Model A components, not later model, hard to find V8 parts. This makes the swap easier and more cost effective because you most likely can use what you already have. With a little bit of homework and know how, this kit makes it easy to install a Ford Flathead V8 (1932-1953) into your stock Model A chassis with very little modification. All you will need to do is drill some holes and make some clearance for your driveshaft, the rest is bolt on. (common hand tools are required for installation) 

Motor mounts and trans mount combo are intended to be used with 37-48 Ford water pumps or 8BA truck pumps only. 

Ford V8 3 Speed Top shift Transmission Fitment:

  • 1935-1939 Passenger Car
  • 1946-1952 Pick-up


PLEASE NOTE: Requires the use of a 1942-48 Car or 1942-1952 Pickup "narrow" style rear mount on transmission. This mount should measure roughly 8" center to center. When installing any 8BA Flathead V8 (1949-1953) into any Model A, the use of a mechanical cooling fan may be difficult. Placing the mechanical fan very close to the radiator. To make this easier, we recommend installing an electric cooling fan.

The complete version of the kit is designed for hydraulic brake conversion. If you intend on keeping your mechanical brakes, please select hydraulic version of our kit. Mechanical brakes version will require fabrication to bracket/pedals and is easily upgradable in the future (see below).
