But the Dominator carb always made a little more power than a big 4150 carb and the 4500 plenum always made more power than a 4150 + adapter so eventually I settled on the M1 4500 + a Dominator as the best combo. I usually used a 2 inch tall 4 to 1 merge type adapter but most cars aren't going to have room for a beast like that.

A little off topic here, Andy, why did you guys make the shear plate/open spacer package so tall?
