Torque Converter? Where am I at? What is compromised?

i'm no authority but a good friend put a 2600 stall converter behind his 400 stroked to 508 in a 72 Duster with 30" tall tires and 3.55 gears. Although they were not wide slicks he could break the tires loose easily at 50 plus mph! Your engine in a scamp without a drag purpose suspension might not be a great fit?
