I have been working on a cummins swap into a 67 chevy C30, a non intercooler VE engine with a NV4500 tran, AAM 11.5 rear axle, and 80 C30 front disk brake conversion. I originally was using a 90 hydroboost unit with the original dodge power steering pump and was having issues with the pedal sticking down and locking up the brakes. I figured that it's was because it sat on pallet for a few years after I pulled it off original vehicle before I used it here. So I upgraded to new lml duramax hydro unit and lbz master like I have on my 01 LB7. Problem isn't as bad now but it still drags after stepping on the pedal. I know the newer pumps have duel return lines, one from the steering and one from the hydro, but people claim that it should not be a issue to have them teed together. It didn't make a difference when I split them on the old hydro unit, so I don't know if there could be a issue with the factory power steering pump, ie difference pressure or GPM. Any insite would be appreciated
