This shows the location of the existing bolt bosses on an aluminum-block LS engine. By using an adapter plate, it's possible to make this existing system work with any iron-block engine, even a 6.0L engine. Hmmm... This shows the location of the existing bolt bosses on an aluminum-block LS engine. By usi When in Doubt, Adapt After converting over to our aluminum block 5.3L motor to do the testing, we spoke with the ProCharger people and they told us they are working on a kit that will adapt the power steering mount to an iron LS block that is missing that one essential bolt boss. We came up with what might be a workable solution. In the accompanying photo, arrow 1 points to the one threaded boss that is common between the iron and aluminum blocks. Arrow 2 points to a threaded boss on the aluminum block that is on the iron block but must be drilled and tapped. Arrow 3 points to the boss on the aluminum engines that is missing on the iron block. If we made a 1/2-inch-thick aluminum plate that bolted to an iron block using bolt bosses 1 and 2, we could drill and tap the plate for boss 3 and merely shorten the aluminum spacers by 1/2 inch and mount the adapter to the iron block. That would allow us to use a cheap, iron 5.3L motor with the Procharger blower.
