Edelbrock LD4B

Sorry again. 1st time posting and I'm having a tough time

welcome, David! If you look at the dates on the post, it will help you. before you posted in this thread, the last post was back in 2010

Where's my manners. Welcome David. What a beauty of a 65 Valiant (American Dart) you have. I re-read your first post and you have a 66 273 with a stock cast 4 barrel intake. The LD4B should make a little difference but I can't say how noticeable it will be. A little more low end power and torque I am sure.
