My engine is a mutt! I just had the radiator rodded out (The guy at the radiator shop looked in it and laughed, looked at me and asked, "This thing ran?"), and while I was at it decided to replace the rusted out water pump. Well, I took the pump off and went down to the auto parts store, and they pulled up a 1974 302 water pump. But it looked much bigger, and different! So I had them look up many other years in the 302, and they were all the same, so for the hell of it I had them pull out a water pump for a 69 351, and sure enough, thats what I have. Now, the bolt patterns are different on both water pumps, so I must have a 351 timing chain cover. And if it matters, I am pretty sure I have a 351 timing chain... Strange eh?
