W2 408 sb mopar on the dyno

Were the cleaner A/F's from your carb?

That intake swap sure didn't hurt... :)

No, the True 950 was leaner, and after richening it up it lost HP! It liked it leaner than norm for my meters.
Thanks guys. I guess I should post pics of the 726HP 427 sb mopar we built...!

Victor intake was worth 10HP and more power everywhere including 3000rpm and the true 950 was worth 8HP and more power everywhere over the 950HP.
