Quote: FWIW I'm using an rpm perf for my turbo 383 and the distribution is beautiful according to my plugs. I use a sheet metal elbow and 5.0 TB. I have a friend who has also had the best luck with distribution and mpg with a DP on his turbo 340. My take away is use whatever intake you would use based on the goals for the car with a carb and not sweat the efi. Other people may have had a different experience.
I really have no experience to refute that experience with....so I don't know. I think all the stock high performance type intakes all tend to have long somewhat equal length runners...but most TBI style intakes tend to be more of a dual plane style...and vacume signal doesn't apply there...so it must work.
