Hello, My name is Ross and I am a Fordaholic.......I have a 1965 F100 that has a 390 and I am looking for info/support as I change over from a 4 barrel to a tripower. I have the manifold (all cleaned and refurbished) the carbs and next step is the fuel rail. I am currently looking for a used linkage but my real delima is where to get the carbs rebuilt. Holly wont answer their phone...How hard are they to rebuild?
