Maybe he meant 123? Sounds like OP needs to get bigger cubes.

The replacement for displacement = $$$

Also, I noticed the video comes from the middle east. I'm guessing he means 193kph

Not 193mi, but is 193 km

that's means is no way to get the number's with stock cubic and different parts, right?

Not without Forced Induction or spraying. That's just a little high for a N/A 346ci motor. Now with a 408 it would just take a good H/C setup.
