390 carb question
I have a 73 crew cab with a 390. The Holley 4bbl has the numbers 4452-1 and 2369 on the air horn. What would be a good replacement for this? Just want good reliable stock performance carb. This was not factory. Somebody installed an Edelbrock manifold and this Holley at some point in the past. Also have some really badly sealed headers and would like to get replacements for those also. Thanks.

The carb that you have on there is a 600 cfm unit. I would just rebuild the carb and save a couple hundred bucks as the carb you have now is just right for stock airflow. Four barrel holley will usually perform better and have better mileage than the factory two barrel autolites/motorcrafts. Heddman or Hooker for the headers would be my recommendation.
