  • 304 with 360 heads?

    Does anyone know if this is a good upgrade for a 304? Has anyone put 360 heads on a 304? how did it work?

    Thanks for the help

    No clue on the AMC engines. I do know 360 Dodge heads on a 318 was a popular upgrade.

      I think the only difference is the valve stems. So you could just put 360 valves in the 304 head. Just make sure it is all AMC stuff, not Chrysler stuff (don't ask).

        CJ,

        For all the knowledge worth knowing about AMC motors go to Bulltear.com. Also, Fuzz401 drops in from time to time and he is a guru on these motors.

          I think they are the same as each other. Not 100% sure, but I thought I saw that the valves were all the same size which makes the swap pretty much null.

            The valves are bigger in the 360, it is a common swap.

              What 47driver said. The older ones are better yet. My 71 AMX 360 has 202 valves and smaller combusion chambers. The better heads were pre 75 for sure, I can't remember off the top of my head what exaclty to look for but I have a list of what cast numbers to look for on my work comp.

                47, I heard that the 360 had bigger valves, It should help with breathing, Highlander if you got those casting numbers that would be cool!

                Thanks

                  the small chamber heads are the 70/71 year 321-6219 casting with a 50cc chamber

                  the 360 heads on a 304 will fit but the biger valves on the 360/401 heads with any kind of lift will just scrape the cyl. wall on a 304 due to the smaller bore and the valves that close to the cyl wall will schroud the valves that you will loose the benfite of the bigger valves
