I’m not old but.... or at least I don’t think I am. My recent ZL1 build consists of a 2015 ZL1 A6. The factory engine was pulled and sold when the car was brand new. The new engine, stroked to 396ci started with an LSA block, Callie’s magnum crank Callies ultra Hbeam rods, Diamond pistons (10to1 CR). TrickFlow 255 heads ported and prepared by BTR, BTR stage3 blower cam, Johnson 2110 lifters. Magnuson Heartbeat 2300TVS blower direct ported for spray by Nitrous Outlet. Squash full return style fuel system with ID850 injectors. 1 7/8 Kooks long tubes with no cats and Corsa 3” exhaust. The drivetrain is stock except for a one piece aluminum DSS driveshaft. I still race the car at local tracks. It’s run 10.44@133mph on 91 octane pump gas. 9.98@138mph on VP109 race gas and 9.62@145 on race gas/ 150 shot of nitrous. I run a 17” Bogart race wheel setup with 305/45R17 Mickey Thompson ET street R radials. The car has been 60’ in the low 1.4’s since I had the rears beadlocked.
