This is the second carb I've purchased from gotta fish carburetors for mustang projects. I can't say enough about their work. I did not end up using this one opting for an edelbrock setup for a 289 project because I found an intake more reasonably than the oem setup. It has sat on my shelf since purchase. The other one I bought from them went from the box to a running car minutes. This carb is ready to go on your project. Thank you for looking at my listing.
