Attention: TDR Forum Junkies Ive been gone for close to a year. 1983/1991 Crewcab duallie project has been on hold, and I am finally in a position to get back to work on it. I have become a "trader" however, I picked up a P-pump to add to my early 91 motor, and I am going with a ported and O-ringed late-model head, hx-35, an ATS manifold, 375 Injectors, and a PDR cam. I know its blasphemy in a first gen, but at least its still a Cummins 
. I previously purchased a 46 RH with a DTT Converter and Valvebody, so I was half way there anyway. Anyway, let the bombing continue! I do have a question however, how many RPM's are the early 1st gen bottom ends good for? I have heard they actually have better Rods and Cranks than the later ones, is ths true? I am gong to call Al or Piers tomorrow, but am looking for other opinions anyway. Would Marine pistons be worth it ? I will be cleaning house soon and will have some first gen parts to sell including the pump, all lines ect... I will post them in the classifieds or e-mail me with any needs. Peace Murfman
