Don't take it the wrong way, your car sounds great but that would be a 700+hp 408 @5800rpm. I am guessing the person running the dyno turned in some correction or something.

The 618HP @5800 is not rearwheel horse power, but is calculated at the crank. The Dyno makes alot of calculations on 3-4 testruns, where it measures the loss in transmission etc.
The Guys who runs the Dyno, says it's correct within 2-3%

I saw a similar engine, with the exact same parts, build by Hot Rod Magazine, make 621 HP in a Dyno.

Mike Drew build an engine exact like mine, but with another cam. It made 564 HP @5800

But You're right.... 618 HP is alot in a 408 Stroker. Don't know if it's correct, but it pulls HARD, and that's good enough for me
