Thanks for response. I currently have a paired (1973) 351W, 5.0 engine and a C6 trans. My original intention was to put the setup in the 1951 F1 truck I am building. I have already reuilt the entire engine with slight hp modifications. Now I'm thinking a AOD trans would be a better choice for a daily driver. I am not sure what AOD trans would mate up to the 351W I have. The overall goal is to get an automatic trans, with overdrive, that will work with the rebuilt 351W.
