Stock 340 dyno tests?

First article, Dyno Derby, is garbage. Stock headed/rocker armed XE268H making almost 400hp, yeah sure it is.

That dyno is known to be a little on the happy side imo.

Not exactly stock heads with a multi angle valve job and bowl cleanup.

Dont think there is enough cam to get it there at any rate.
