    These are the only two I know of http://www.goodvibesracing.com/magneto_offset_drives.htm
    I run the dunn, it's not a very stout piece. It needs a spacer between the manifold and the bolt hole in it, this is a must or when you tighten it it will bend it and all sorts of bad sh.t will happen( it all falls apart ). I pinned the press on 5mm sewing machine belt drive wheels so they wouldn't slip. It works prety good now though. PSI was working on one years ago but I don't think it ever came to be.

    Lots of options

    Do you mean an offset to run the mag in the standard BBC location (back of block), a unit to run it up front off the gear drive (like a Hemi), or a front drive to run the mag and pump straight off the cam?

    Fuel Injection Ent sells a very nice and very affordable unit to drive the mag and pump straight off the cam: http://fuelinjectionent.com/webstore/product_info.php?products_id=190

    RCD (download the catalog here: http://www.rcdengineering.com/catalog/request_catalog) makes 2 types of front drives, one that runs off the gear drive (so the mag is vertical like a Hemi) or a dual drive to run it off the cam, straight out from the block.

    If you're looking for a total custom built piece, Leonard Hain builds both rear drive and front drive units: http://www.haincompany.com/?racing

    Mike Dunn in TX also builds rear and front drive units, he doesn't have a web site but you can search the archives for his phone number, i'm sure someone posted it here before.


    Hope that helps
