Does anyone have a bellhousing and dowel position or original ford engineering drawing. I am about to make an adaptor to a v6 gearbox to fit into my car. If no one has I will post my measurements once found here.

I too would like the factory engineering ‘cylinder block’ drawings for the Ford Y.  I need them so that a CNC machining center can be programmed appropriately to machine the Ford Y.  Anyone out there that has those blueprints or drawings for loan or sale, just give me a shout back.

For other needs, I have ¼ inch thick aluminum plates with the FYB bellhousing pattern that I use for making adapter plates that allow the use of non-YBlock bellhousings on the Ford Y.  Here’s a picture of one of those plates.  Those same plates have also been used to make Ford Y adapter plates for the DTS and Super Flow dynameters.

This is what I came up with I tried making holes equally spaced off the crankshaft centreline but had to adjust slightly to work with 4 of the easy to access y blocks I have here. These measurements are metric in mm (sorry US people) and places the crankshaft centre within 0.1mm on all of my engines. I checked using a plate I laser cut with a tight crank hole.
