the wiring is not that bad if you can read wiring diagrams good. I got a subscription to alldata for my truck and the donor truck which made things much easier. it has pinouts for all the connectors and shows what they look like for easy ID. and excellent wiring diagrams. the main 2 things you will need are GM part # 12563532 which is the crankshaft spacer. and a set of engine mount adapter plates. I don't want to give you more parts untill I know what you are putting it in and what the engine came from. But will be glad to help in any way. This is a great forum to be a member of if you are going to be doing a swap of this kind. Many knowledgeable people on here. with the help of these forums I got my swap to start and run on the first try without any problems. good luck to ya if you go thru with it.Originally Posted by khumphreys
