See if you can borrow an MP M1 to test, too. Although the Victor might make a few more HP than either the SD or the M1, the others probably keep the torque curve up better below the peak and help a heavy car w/ limited stall speed off the line.

BTW, I've run both a modified M1 and a Victor on my car and have no idea what people are talking about when they say the Victor is a "light switch" at low rpm. The car ran virtually the same w/ either intake and street manners weren't any different from my perspective. Both intakes responded well to using carb spacers, too, if you have the hood clearance.
