5. Scat also let us borrow one of its 5.7-inch rod stroker kits, so we could illustrate the pin placement differences between it and a 6.0-inch rod kit (left). The longer rod length and stroke places the pin boss in the piston up into the oil ring, so the whole package fits within the (nominal) 9.025-inch deck height of the typical small-block Chevy. Many theories (and some myths) circulate about the advantages and disadvantages of certain rod length to stroke ratios. Some believe longer rods place a reduced load on the cylinder walls, which minimizes premature wear on the thrust side of the cylinders. For big-horsepower, high-rpm engines, that is something to consider. At the power level, we expect to see it’s a non-issue.
