Some rodders doing V-8 swaps like to put the front mounts in the forward set of holes on the front crossmember to gain more room for the distributor or valve covers. All of the swaps that I have seen like this were either automatic or had hydraulic clutch linkage. If GM had allowed for the stock clutch linkage to work with the engine in the forward position, I am sure at least some of these swaps would have used it.
The forward set of holes is used the right side only with the 292 because on that engine the locations of the mounting holes (on the block) and the fuel pump were reversed when compared to the 230 and 250 engines.

So are you saying the four speeds all sat back? it was my understanding that all of the v8 (except 4x4) sat in the forward holes. If so it wouldn't be the first time I've been wrong...just ask my wife 
The only reason I didn't change to the front holes is because I didn't want to have to get a longer driveline. I didn't even think about the clutch linkage, as a matter a fact I had to modify it to work in my current setup.
