Johnson 2126LSR Pushrod Length
First off let me give the mods done to the mechanical side of the car. Lifters are Johnson 2126LSR, Upgrade Valve springs, BTR Stage 3 supercharger cam, Valves are stock, Head Gasket is stock, the heads are stock as well(I.e. no milling or porting done) now I am getting a consistent reading of 8.050 on all my intake and exhaust ports with zero lash on them. One of my friends from Katech told me that the 2126LSR are .200 shorter then the stock lifters currently in the car which is a 2017 Chevrolet Corvette Grand Sport with the GEN V LT1. So with my math being correct I am getting a reading of 8.075 WITH PRELOAD ADDED (0.30 +- .005) I am opting for the 8.075 since when the engine warms up it’ll bump the pre load up to perfect spec. I am wondering if there any other people currently running the same set up as me that are getting the same reading for pushrods?
