Yeah a thermoquad. Great throttle response on the street with the big kick of the secondaries. You'll make a bit more hp with a holley type carb, but you'll also carry a screwdriver in your glovebox.
Best street carb I ever had was a TQ on my 71 340 Cuda and provided dang good fuel mileage in town. Don't know about highway because I never got out on the high way but would think it would have been good. Holley carbs never produced good mileage in town but had one car with a 289 that knocked down low 20's with a 600 DP. The car had 2.80 gears though. The Cuda though, was a car I should have kept!
