HPR and GSpeed team up on a 468cid LS Road Race build - Part IV

Final pieces before we hand it off to Louis and the crew at GSpeed for their drive assembly, sensors, and wiring harness.

One of the things that Billy Godbold had tested with using the new conical single spring and Comp lobe design was the OE rocker and a new Comp design. Since the Comp rocker is still in development and not ready for sale, we went OE on the rockers. A large part of the goal of this first build is to choose proven components using a sensible budget, and with Billy's spintron testing, there was no worry on the OE rockers.

Louis at GSpeed took the time to pull them apart, tumble them, polish and install Comp's trunion upgrade kit before sending them over for install on the engine. New Trick Flow rocker stands locate using two dowels into the cylinder heads. Due to some tight pushrod clearance, we are using a heavy wall 3/8" diameter pushrod for rigidity as our typical 7/16" would not clear in this case.
