    Good Morning all!

    So I have gotten over the funk that beset me last year and I am going to make the go-fast engine work.

    At this point I would like any info or suggestions on rocker setups to use.  The engine builder used the stock early cast rockers and cross drilled adjusters.  I would like something better.  Much better.  And reliable.  

    Thanks,

    Lester
    Supposedly for a 1380 engine

    And where would one purchase a decent roller rocker setup?  

    Thanks,

The valves open too wide and compress coils of the valve springs against themselves. I am using heavy springs. I am not sure what I will do about this. I hope a switch to a 1.5:1 ratio rocker will cure the trouble. I will be putting this engine in my sprite with a 4.55:1 differential and a Datsun 5 speed gearbox.

    This is where I am now!  After spending the money for a go-fast setup?  sigh.
