Stroker small blocks - what intake?

2" of vaccum is a lot. Try the carb first, you may also try the bigger carb with no spacer, then with an open one, if you can get to a track..We're on the 10th or so straight day of rain, they say it should dry out tomorrow, so maybe NE tracks will be open again...lol. The Strip Dominator looks similar, but I'm sure it's got less volume in the plenum and ports. Also, the ports tend to be shorter, which is why the power band is listed as starting at 3500. You may just find the carb is enough to get you a little more power, with no loss in lower end, where the manifold and carb might lose you a little down low, to get more in mid and higher ranges.
