The 2 participants involved both know Oldsmobile very well. I'm not surprised by the number(BULLSHIT, that's damn impressive!!). The question is: how long will it hold?

You don’t need to turn it that hard look at the torque it made down low if you get your Shift recovery RPMs to fall in the sweet spot it’s going to pull like a freight train and from 6000 to 6500 it only gained 7 hp that’s just the glory pull on the dyno

Wait til Dan has it in a car and you see the numbers he runs. He is a badass racer.

I knew he liked 403s (so do I) but it looks like he went "full bogey" with this one. That's an impressive engine and I also think there's no reason to spin it "high."
Hopefully he has a very light car. He doesn't post much anymore so if any Florida guy's see the car in action, please keep us informed.
