i know that the rockers are garbage i had the heads off and had the valves done and looked at these things and said to myself , what monkey designed these, used to chev rocker and dodge rocker rails that kind of make sense. the things are also really heavy
i am not shue what size heads re cc,the pistons are the bino top which i think are 10 to 1.
i am looking into the theory that the stock cam is terribly retarded and that some gain can be had by advancing the cam 6 t0 8 degrees.
the chain and gears are original so it would be smart to change anyways and advance it a bunch.
i am not very camshaft smart re duration degrees but am looking at some ideas.
