I didn't see the report from the dyno reading on there at all. 345 rwhp is pretty high for one of these gutless wonders. I know he's been putting a lot of time and money into his engine to get it. But........worth it, not really IMO. In the long run stuffing a cummins in there would be a better option, or just buying a newer truck that you can just reprogram to get higher numbers then that with ease. Yes he's done a good job with his engine IMO, I personally just don't think it's really worth the trouble or expense.
