I am hoping to one day put compound carb system on 51 Special with 263 straight 8. I have the dual intake manifold from a 41' but no exhaust manifold or risers for it. I am trying to decide if I could run the stock dual carb manifold but utilize headers? I am thinking I will have a problem since there will be no heat riser although my current single carb system riser is currently stuck open and it does not pose much of any issue. I do have (2) risers each from separate single intake systems but it does not look as though they would adapt easily to the dual system. I know that the stock manifold systems split the carb barrels so that they feed front and back cylinders. I am wondering if fabricating an intake with mandrel bends and balance tube along with headers would be easier or better? Thinking of using 2 Strombergs (4 bolt) because that is what I have. I am posting a video of a guy who looks to have successfully done it using I think 2 Holleys. Anybody our there done this?
