Bought this 64 GMC about 2 months ago. $500 and a clear title and I drove her home. Was missing like crazy and found that 2 plug wires where crossed. Has a blown head gasket and am in the process of fixing that. Here's a video on it after the tune up. I mention it not having a knock in the video...there's alot to this story I haven't mentioned. lol Here's a couple more vids as well for the heck of it. She's been named "Crustine"
