It is a custom setup i bought off ebay I wouuld suggest it i bought it from a company called novak industries I havnt got the hydroboost working yet so i cannot give you much inputWhat kind of Hydroboost set up did you use? I am building 1970 and still trying to get all the parts together.
Sure does to me also. Bleeding the injector lines won't help at this point. The air is already out of the injector lines. Hopefully it's an injector, or possible a broken valve spring. I wouldn't run it untill you eliminate the possibility of a broken valve spring.Sounds like it is missing on one cylinder???
