Ls1 Engine Build Pushrod

Enough with the theory, back to practice. The range of possible hydraulic lifter preload can be confusing (pushrod length measurement is much easier for solid lifters), but just adjust the checker so it's firm against the inside of the adjuster cup and the end of the checker is difficult to spin (thanks to friction). Remove the rocker assembly, take the checker out, and measure its length using a caliper like our Powerhouse unit. We get an overall length of 7.850 inches. Repeating the process on the exhaust, we wind up with 7.890. It looks like we're in the range of 7.900 for the correct pushrod length (they're normally sold in increments of 0.050 inches).
