904 for drag racing

Okay, I went down to the junkyard today and pulled a 904 core from a 73 coronet with a 318. What will I need to build it for drag racing behind a 360? Are there 3000+ stall speed converters available? It will be going into my 66 which should weigh about 31-3200# when finished. How much can I expect to spend?
Thanks,
Jeff
