The holes in the flexplate for the converter will have to be re-drilled to the pattern of the 350 converter. There was a feww 153 tooth flywheels made the have the correct pattern but they are hard to find and the re-drill is a simple deal. You may be able to find a bracket for the kickdown cable on a 71-76 Nova pass car equipted with a 6/350 combination. I am sure there were some pick-ups made with that combo But I don't recall ever seeing one. Paul
