Low Profile Single Plane Intakes

Holley Street Dominator or Edelbrock Street Master? The Holley Street Dominator is very close height wise to the stock 273 four barrel intake. I would run the Street Dominator with the 360 with 2.02 308 heads. If you ran the 408 360-1 head combination and wanted the somewhat stock appearance, I would run an Edelbrock Torker II and would see about having it ported. It's probably the largest single plane your'e going to find that resembles a stock intake.

Either way, that whole affair of a high geared lightweight car sounds like a whole lot fun, even more so with a 408 dressed to look like a 273 Commando!
