[QUOTE="Cyborg, post: 88531, member: 3426"] Yes, I have done it that way before (sort of), but you have to make sure you have the face of the timing chest perfectly flat. The areas around the threaded holes in the case tend to stand proud, so they have to be levelled off and same with any hash marks on the mating surface etc. I use a chunk of parallel cast iron with a piece of tool stock clamped to it and then take measurements starting with the large idler boss. To install the spindles, I used a setup where the spacer was referenced off the parallels resting on the case mating surface instead of up against the case around the spindle bore. It's a but fussy trying to get accurate measurements, but you can make individual spacers.... at the end of the day, you will likely have to adjust one or two of the spindles with a slide hammer. I'm no expert at this, but I think the best thing would be an inflexible chunk of steel made up like a steady plate. When the cases are hot, all of the spindles could be set to the same height as the large idler. I'm not planning on making a plate, but may make individual spacers. Doing these timing chests tend to make my head want to explode. Sorry for the crappy photo. I also install a ET173 on the spindle to make it a bit easier to get an accurate reading. My new large idler spindle reads .3755 above the mating surface and the small idler spindle (which I believe was undisturbed) reads .3790 , so not within the "Instruction Sheets" .419 to .424" [ATTACH=full]17939[/ATTACH] [/QUOTE]
