No! They are for a car with a big cam, a 4-speed, and a some
gears. We use a 600 DP on our '65 coup track car. It has a
351 Cleveland, Toploader, and 3.50 Detroit locker. They do
nothing for a car with a auto. What are you working on? Most
of the time less is more! My wife drives a '61 Ranchero with a
450 holley and it runs great!. We just ran a friend of ours with a
427 '66 Fairlane and got him from one stop light to the other.
If we where on the highway he would of pulled us but in a short
run we got it.
To big of carb, or to big of a cam, can make nice car real slow.
And a real drag to drive.
