Thanks to all .The injection system was only partly there No harness ,computer,injectors,much of the system was no longer there, So i went carb.Ihavent worked on any chevy motors in years .I have built meny older 58-65 283,327,427, but never did anything on any of the newer motors . Most of the emisions and hoses and conections were no longer there.I assume, by what some of you have posted that the hoses i am asking about are frome the filter assembly to an oil cooler .Again as i sead there is nothing there the hosses wer cut and just sitting there.The engine i purchased came with a 700 r4 trans which i will be.Would it make sense putting in a cooler.This is just going to be a mild street engine for my 58 fleetside .Thank all of you for the help Tony
