Up for sale is a nice edge 3500 converter for a dodge 727 for a small block. We built a 408 and installed the converter and it wasn't enough for what we needed, only has a couple passes on it, and was pulled to put a 4000 in. The converter is basically new and has been on the shelf in the garage for a few years now, no longer need. My loss is your gain. The converter is prefect for a street car. 

Thanks for looking
