inatalled on: 1969 Plymouth Roadrunner, stock 383 auto p/s a/c. Was running a 1405 Edelbrock, but wanted to go with more cfm, and this was pretty close to the original carb. Install was really easy, set up too.....fine tuned it and it has run top shape ever since. My car is stock so there are no cams, etc. but it runs real strong with this carb...good for a stock or mild set up, easy to tune.
