John, You are right. The block bolt pattern is the same. You need to use a 727 from an A block for these adapters. The main purpose of the adapter is to allow the use of 62 and later torque converters and flex plates. The method the later flex plate is centered on the crank is different.

The Wilcap adapter is 1" thick (according to their website). In addition, there is a crankshaft spacer (unknown thickness). The original spacer between my hemi and powerflite bell housing is 3/4". Based on the pictures, it looks like the flex plate and the hemi 8 bolt crank have the same bolt pattern. It also looks like the 727 uses the same bolt holes in the hemi block as the old bell housing. There must be a reason why you couldn't just bolt everything up without the adapter, assuming a cut was made to allow the reduction gear starter clearance to bolt to the tranny. Has anyone on the list used an adapter like the Wilcap unit?
