Question? Do these Callies MOPAR blocks (a.k.a. World type) have both the Chrysler and GM transmission bolt patterns on the back? And is there any way to use a Chevy type starter mounted to the bottom of the block when using a "stock" Powerglide? Or is the starter "problematic" when using the GM trans. This picture's method of using the MOPAR location? (and I imagine a midplate that has studs for the starter), is crude; and a lot of metal removal from the stock case.
