Some of these estimated hp #’s surprise me for a pro built & tuned, Thitek headed 426”. What am I missing?

Maybe I read it wrong but thought this is the tired shortblock dyno before switching to new engine?

426 before header test is how I understand it.

How much did it make before?

Went from 931 to 972 or something. 40whp gain at the same ECT. More surprising to me was the huge difference between 150* and 170*… it was enough to nullify the headers on the first hit.

So it made more with headers or no?

 

[Unholy707]

That’s a pretty good gain

 

[Unholy707]

Did they retune it for the headers?

 

[Unholy707]

What I’m hearing is I didn’t waste money on agony. Nice

 

[Unholy707]

Expensive 40 whp though
