My buddy across the street who owns the local speed shop has done quite a few stout 460-type engines, including one in a friend's steel-bodied '56 that was running in the 8's (unfortunately, it recently got chummy with the guardrails at Sacramento-several times). I was looking to get a Victor 460 for another friend's '66 Fairlane with a 466/ SCJ heads, has a tunnel w/ 2 660's now. I was figuring on a Dominator setup, and he swore that the 4150 flanged intake with a Dom adapter ran way better than the regular Dom flanged intake- back to back on the dyno, and on the track. Makes you think a little, as the area of the 4 throttle bores of the Dom are probably still smaller than the open flange area of the 4150 manifold. Seemed to get a more homogenous fuel/air mix, and was more responsive to jetting changes. Considering all the different runner length/ plenum volume/ shape combinations that get massaged, it wouldn't be the first time that something that doesn't seem to make sense actually works LOL
