What is the lightest power steering box available to run on an imca modified? I thought a Buick Grand National box would be it, but it is just as heavy as other boxes I've seen. I've heard about a Chevy S-10 box, but I haven't seen one and I don't know what year truck. Does anyone out there know what is the lightest box?

The lightest that I am aware of is the 605 metric box. The easiest way to identify is there is not a bolt on top cover. It is round and held in with a snap ring.

Yeah, the snap ring boxes are supposed to be about five pounds lighter, but are weaker. Is this Jared? Are we gonna see a orange 01 Mod next year? P.S. The only snap ring box I ever had, was one off of a metric malibu.

The 605 boxes are out of an el camino, and are what Harris uses. They are very light and very easy to rebuild. Please don't pay the outragous price Harris offers these boxes for. If you have a junk yard man that is knowledgeable, he should have no problem finding one. Make sure to keep a spare though, as mentioned before, the main gear shaft bends (or twists) very easily.

I am no epert on this, but there are three different metric gear boxes and the 605 is one of them. The others have bolt on top covers, one has 3 bolts and the other has 4.
They are both about 5 to 7 pounds heavier than the 605. The 605 has the small pitman shaft and requires a standard steering pitman arm from early chevelle if you use it on chevelle clip. If you use it on metric you just bolt it on. It is weaker, if you change over get spares.

Thanks custom, have never seen them on Regals, but wil keep an eye out for them because El Caminos are getting hard to find.

I have ran them in the past, the 605 gear box is hard to find anymore, and YES they do brake easier than others, I went back to the other metric boxes simply because they last longer. They both cost the same, i would go thru 2-3 605 boxes a season. For the cost, you don't save alot in weight with 605 box.

Jeep Cherokee Z box is a perfect fit, I'll weigh one and post the lbs. They dont break either.

I thought I had read at one time that the steering boxes with the round ring retainer were a variable ratio. This was to decrease the feel of oversteer on a street vehicle while turning. Is this right or wrong and would this affect the steering feel and actual steering in a racecar application?

WHAT ABOUT LIGHTENING THE HEAVIER BOXES? LOOKS LIKE THERE IS A LOT OF MATERIAL HERE THAT COULD BE REMOVED. HAS ANYONE TRIED TO DO THIS?

I don't believe it's legal in IMCA to lighten the steering boxes. I'm not too sure It'd be safe, either.
