Realistic Expectations - 11 second Demon weekly driver

A buddy of mine had a '72 Duster with a worn out 383 in it. He wanted a fresh engine so we built a stock stroke 400 with RPM heads (Stage II porting by Dwayne) and a small Ultradyne roller cam. Car had Hooker fenderwells in it which are crappy but that is what he had. Car had full interior, full exhaust, street tires, all steel, etc. He drove it to work and around town. It was a little lumpy but driveable. Car was deadly fast with the new 400 engine. He took it to the local track and ran a stack of 10.90 @ 122 mph passes until someone he beat complained and he got kicked out since he didn't have a rollbar.
