I Have A 99 Ram 4x4 With A Autotrans, I Have Look Every Where On The Block And Cant Find The Block Id#, The # Is Not Below The Injector Pump Or Anywhere Above The Oil Pan Around The Whole Engine. Im Hoping The This Is A Good Sign That I Dont Have A 53 Block. Any Other Locatin That I Sould Look To Find Out What The Block # Is?
