Pacers are known as water leakers and basically junk when new. I worked for AMC during those years and they were all intents and purposes garbage. The hornet 6s and Gremlins etc fine But don't get pacer it was a hot in summer and cold in winter and just about fell apart when new. Now a 304 Gremlin was nice I several with sticks and they ran good to 4000 By the way 8 grand on AMC engine is bit much the majority were done at 4K and the rocker pedestals came apart easily
