Good evening , I have been following your posts about 3406 Cat engines. I am having trouble trying to find parts for the combination that I was running in my truck, not sure if you can shed a little light on it? It is a 3406C block with a B fuel system. The pistons that I just pulled out are Cat #126-0736-00. The skirt # is OR 8232. Obviously this is a 2 piece piston with a steel top. It has a rod bearing # 323-5573.It has 8290 nozzles. I am having trouble locating cylinder packs for this thing. I was hoping to go aftermarket with IPD if possible. Engine serial # is 3JZ37756. Could you please help out with any info you could? Thank you
