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.

I can talk to the car owner for 5 minutes watch a run and tell you for a fact if it’s an underachiever. Been doing it for decades.

You might not be able to, but other of us can. And do.

It never ceases to amaze me that guys who can’t build an engine (that means doing the machine work and the tuning) come on forums like this and argue with the guys who can do it. It gets pretty ******* old, really fast.

You are knocking an engine build whose work you can’t possible duplicate and then claim it’s bad numbers and ****.

**** that. I know I‘m tired of the ****. And IIRC you argue header size like an expert but your testing is minimal at best.

Same ****.

You don’t have a ******* clue what it takes to make 650 horsepower or how to tune it, or how to make it get down the track, or you’d be doing it.

You just write the check.
