My 5.7 tbi motor just went out on my 93 k1500. Its dark so I am not sure what happened but I lost oil pressure and oil is everywhere. I will get a good look tomorrow evening. It made no funny noises and was shut off immediately. Im not sure about having this motor rebuilt, especially being 2 hrs from the closest machine shop..So I am wondering if anyone has any recommendations or good luck with purchasing a new short block or possibly long block from any certain suppliers? I want to get a new 5.7 vortec short block and swap my new parts onto it. Im still thinking of keeping the 193 swirl ports since my new intake wont fit the vortecs and Im concerned with the coolant issues everybody seems to have. Any insight would be helpful...This will be my first actual build. Thanks
