This is for a Holley 4010 as you can see from the pictures it is very clean . I bought it to put on my jet boat however I went another way so it never got used by me. I don't need it so my loss is your gain. It was not bought new. But does look freshly rebuilt. It is 750 CFM 

4 Barrel double pumper. 

This is an as is no reserve auction I ship only to the lower 48states thank you
