I checked the archives and some people are changing from a 7 pound cap to a 10 pound cap. I believe one needs to change the radiator neck from a 1" to a 3/4" to change the cap. Have people noticed that the new cap is fine and not over pressurizing the radiator and making it look bloated? Any other issues to watch for? Thank you, John Spaur San Jose, CA '62 BT7
