You learn something new everyday. How long will an LA small block hold up at 550 horsepower

We don’t know if something is an underachiever unless we know what it runs and weighs, and what the combo is though, do we.
I have nothing against Brian, by all accounts he runs a nice shop.
As a business owner myself, it’s good business to sell the sizzle. Like I said, knowing how stuff ultimately runs says a lot about the validity of the numbers.
For my part, I am not gonna assume the two guys with the 650 horse heads put them on doggy running combos without track numbers And or more information than just saying they made 650 horsepower.
As I mentioned earlier, I wasn’t upset to hear that heads I was proud of and ran good (W5) didn’t break 300 on two very,very respected benches.
Numbers, I have found by personal experience, don’t mean ****. it didn’t embarrass me, it was just reality. Is what it is.

Been around enough stuff off Brian's dyno to know it isn't some fluffer deal like some guys out there. A bunch of stuff runs pretty darn close to what it should in a sorted out chassis. Selling stuff that has fluffed up numbers will usually end badly and is bad business, IMO. Talk about something that will NEVER run the numbers. Fluffer stuff is that. Look at the build MM and other mags have done and the disappointing numbers at the track if it every actually makes it there.

One old and popular Chevy builder was notorious and blantly used to talk about "numbers sell engines" and his stuff was always fluffed up badly.

Just watch old "pass time" episodes to laugh and be amazed at how overblown at output some people think their stuff makes.
