Which Carb Gives a Balance of Power & MPG?

Heres my .02$;

Edelbrock; Dont bother unless you want your car to reek like raw fuel all the time.

Thermoquad.Dont bother unless you have spare parts and know what you are doing. I have 6 tq's but only run 1.

Holley. Expect to tune it unless you get lucky.Prolly should buy a holley book and a tune kit.

My take is a little different.

Edelbrock; Takes time to tune them up really well. You'll need there kit of jets, rods and springs. Perhaps even (Though not likely) a squirter pack.

These carbs are very good in the street and fairly decent performers at the track. I like the AVS models myself.

ThermoQuads. I'll have to agree here. But I do like them. For a mild street strip engine or just plane old hopped up, these carbs are good. But learn them before tossing it. It may very well give you fits. There a bit particular on how there set up.

Holley; This carb will run the best MPH and has super tunabilty that will take on a lot of kits for a lot of tricks. In it's basic OOTB for, a jet kit is all you should need to tune it. Maybe springs for the secondaries.
