That cracks me up. ATI flat out refused to build me an 8" for my BB 493 because I street drive my car.
That's weird, they built my 8" converter for 25% street use, although it's been several years now.
I always used 8" converters in my 9 second big block street cars. My current car is 95% street and I'm hoping to squeak into a 10.99 with a 9.5" Dynamic converter.
