I have a 92 model GM Performance 350 crate motor for sale. The engine run perfect and strong. The engine comes complete with all the accessories, ready to drop in and run. I took it out of my 86 Blazer last night, because I have a vortec 350 ready to be installed. The block # is 10066038. I will take 550 for the complete engine. The engine has 37579 miles on it. I have the reciept of the swap into my blazer when this engine was put in brand new. If you have any questions, dont hesitate to ask.
