Holley Strip Dominator for the street?

How does the Holley Strip Dominator fair on the street? I just got a built up 360 with a strip dominator, kb pistons, Racer brown 238 duration cam, J heads with 2.02/1.60 valves with the intake and exhaust ports ported. With the 68cc chamberes (I cced them) it comes out to be 10.07:1 compression with the .050 gaskets. This is all hooking up to an A833 close ratio 4 speed, 8 3/4 wih 3.91's, in a 72 Duster. The owner thought the 360 was pushing a little over 400HP, and with a more radical cam and 4.56 gears it was running 12.20's in a 68-69 Coronet.

Anyone run a Strip Dominator on the street, and would it be worth swaping out to a MP M1 (whats the difference, they look the same) or an Eddy Air Gap. I have the Holley, so would it be worth the $ for one of the others?
