The chosen drive-train for the racecar is a LQ4 6.0L “LS” engine and 4L80E transmission out of a 2001 Chevy 2500 pickup truck. The truck was purchased complete for $800, and resold for $300 once the engine, transmission, drive shafts, computer and wiring harness were removed.
Basin 4×4 of Klamath Falls donated a set of 706 aluminum heads from a 5.3 car engine which will bump the compression of the LQ4 from stock 9.4:1 up to 10.4:1. In addition the heads have been sent off to get CNC ported and polished. Cullen specked us out a CAM and valve-train upgrades that, when all said and done, should provide a healthy and reliable 550 hp!
