Low Profile Single Plane Intakes

Another vote for the Holley Street Dominator. The Streetmaster looks VERY stock too, but one look at the 318 sized ports and plenum bottleneck would rule it out for anything bigger than a 273/REALLY mild 318 build.
The Torker II looks like a good possibility, but I've never used one so I can't comment on it. But I would beware of the later issued ones that have an offset thermostat- that would also kill the look, especially if using the correct Commando-era T-stat housing.
I like the 308s for this build, as the aluminum Indy heads would kill the Commando look almost immediately.
