| RE: Carb selection for a 390 Mustang |

I just read a great artical in the last Car Craft magazine wrigten by the guy that owns Demond Carburators. And it had a lot of great pointers. Here are some
Larger CFM means better high end and lighter car. Small CFM means better low end and a heavyier car.
Higher comp. Larger CFM
Lower Comp. Samller CFM
Anual discharges better Low end
Down Legger Discharges better High end
Carb, Intake, Cam, and Gears it's all about where you want your money made.
Up Front but not as much (Low End)
Up in RPMs and more (High End)
Really think If your makeing this thing to fly down the highway doing a Buck Twenty go. Go for RPMs that's what your useing. 6-7000RPMs
If your hiding out on some small road doing 1/4 mile go for the middle 5-6000RPMs
Just messing around at street lights and getting so so mileage go mild 3-4000 RPMs
Rember RPMs = More coast
I have a 64 Glaxie with a 390 with an RPM Performer intake & Cam, and stock heads with 3 way valve job, C-6 with 2400 stall funning a Edlebrook 750. |
