Help! I have a 428cj with a adual carb setup. I am running 2 4150 holleys. I am down to purchasing a distributor. I can find one that the bowl won't hit the front of my carb. I have tried a mallory 5505301 and MSD models 8594 and 8595. None of the 3 worked. Any suggestions? I don't want to switch to a single carb intake..
