Tuf-Enuf Racing Engines
To precisely shorten bolts in the lathe, I made slotted collets for each bolt diameter. They are fractional in length to measure off the end, so you know where to cut for your length. I’ve used large O.D. valve guides and aluminum round stock. Just make the collet big enough to clear the bolt flange, hex or socket head.
If I’m not using torque plates, I tape up both sides and trim out the bores. I use painter’s tape, which comes off easily and doesn’t leave any glue residue. I get much less oil in the spray washer this way.
Next time you have set of large journal small block Chevy connecting rods to resize, consider honing the big ends of them for a +.002” outside diameter bearing that the LS engines with fracture cap rods use.
