SU Troubles

[mgbracer@aol.com]

    Ok, I've meshured the play on my throdle shafts in my SU's with a dial
indicator and I get .004" play.  I checked some junkyard HS4's and they read
.015"+ I know these are bad, but is .004" acceptible for an SU?
    By the way Scott It's not soo much that I'm too cool to spend $6,000 or
more on a race engine. It's that the feeling of winning is some much better
when you have 50% less HP than the competition. 
Now if I could only win once.... ;-).
