I bought a 1968 Buick Riviera well more stole it with the price I paid. It had been sitting in a garage for 20 years and not moved. I bought it towed it to my house and had it running a few days later after I bought a new coil and new points. The old coil actually was probably fine but I changed it out anyways. It has the 430 motor in it, and I was wondering if anyone has a wire diagram for this car. I bought a repair manual at least i thought it was, turns out its for the body not the motor or electrical. I have found a page where the guy uploaded alot of information about a 64 riveira but im not sure how many things changed as it was the year for federal safety things. I drove the car around my yard and I started taking the motor apart now. Mainly because I want to put new gaskets on it from the heads up and clean the motor up to show worthy. I was going to go more HP but I am doing everything with my daughter and I don't really want to get into all of that a quick pull of the motor to clean it up and drop back in is ok with me. However, who ever worked on it before cut a lot of wires and spliced into them so i want to start there and make sure every wire is in the factory spot and nothing else added. Thanks everyone.
