If I ever get all my parts it is "supposed" to make around 1100 horsepower in the Coronet with about 3650 pounds and 30 inch drag radials. It has a Dana and will be street driven 75% of the time and WFO the other 25%. Would a 3.55 put too much load on the driveline or would a 3.73 work better? It has a 4.10 in it now, I am leaning toward the 3.55.
