Don't matter how many cubic inches, just wondering how fast you can make one go without boost or nitrous. I'm sure you can put one in a light weight dragster or roadster and haul ass but I'm interested in times on some door cars, tube chassis & backhalf 2500lb range. LS swaps seem to be the way to go but will they make a 3500 lb Chevelle or Camaro street car as fast as a Big Block?
