Guys, what is your real-world experience with old school low rise multi-carb intakes for street driving? I'm looking at swapping on either an old Weiand or Offy 2x4 with a pair of 500 Edelbrocks, or an Edelbrock F380 with triple Rochester 2G carbs on the stock 390 in my 66 TBird.
I realize that neither of these will be optimum for performance, mainly I'm trying to add some visual appeal under the hood, and lose the weight of the stock cast iron intake while I'm at it. The TBird has a very low hood line, so it has to be an old school low rise intake. The guy who has the 3x2 setup for sale claims that he was able to get 17 mpg out of it in his early 60s Galaxie on a long highway trip, which is pretty decent for an FE engine.
Am I correct in thinking that the 3x2 will probably be better suited and more responsive on my stock engine in a heavy car with 3.00 gears? The only downside I can see to the 3x2 with the 2G carbs is that they will look a bit lost on top of that big engine, whereas the Edelbrock 4-bbl carbs will have enough size to make a better visual impression. Of course choosing the right air cleaners will make a difference to how it turns out as well, I won't be able to go with anything that is very tall.
Suggestions, opinions, your experiences?
cheers
