Default most NA hp out of 3 valve?

the most wheek hp i have seen at the wheels of an NA 3 valve s197 was about 420hp, what is the highest you have seen? or what do you think is the most possible? and it doesnt have to be using the stock s197 block..but it needs to be a 3 valve.

BBR got like 406 on a pretty extreme setup, stock displacement, but they were maxing out the injectors so i dunno what it would have made.

I am not quite sure, there are multiple options of pistons available so it all depends on what you get..
