I have a Holley Street Dominator single plane, spread bore intake manifold for a SBO. This manifold is in good condition. I also have a nearly new SMI - STAGE TWO - (800 CFM) ROCHESTER QUADRAJET that I used with the Street Dominator on my 403 in an 85 Cutlass and ran a 12.42 in the 1/4. I am no longer able to work due to age, and Social Security does not provide for the car hobby. I want $175 for the manifold and $295 for the Q-Jet. I live in Macon Ga. and will pay $30 of the shipping cost. The intake is 25 lb. and the carb is 12 lb. PM me or email Larry (Shanghai) Smith for more pictures or if you have any questions. Thanks for looking.
