Vehicle Description
1998 Chevrolet Tahoe LS9 Swap Light Pewter Metallic 4WD
Although the original Vortec V8 was intact, the decision was made
to install a new LS9 crate engine from GM, as well as the
accompanying performance components to accommodate the Dry Sump,
supercharged 638 horsepower engine. A strengthened 1-ton 4-speed
4L80E automatic transmission was added along with upgraded 6 Piston
Baer brakes on all corners, Superlift lowering suspension,
35-spline Dana 60 rear end with Detroit Locker rear differential,
upgraded trans and engine cooling, custom traction bars, and much
more. The engine swap and the installation of its associated parts
were all performed by a Chevrolet dealership! Yep that's right
folks the big bucks were spent to do this one by the books!
The Baer brakes use cross drilled and vented rotors measuring 14""
in diameter up front and 13"" in back. The new 20? GMC alloys wear
Goodyear Eagle LS-2 tires. he 6.2-liter supercharged LS9 V8 is a
hand-built crate engine from General Motors that was installed by
the technicians at Titus Will Chevrolet of Olympia, Washington.
Wicked Fabrication in Auburn, Washington provided the custom
fabrication work and also serviced and tuned the truck throughout
the first 1k miles of break in. Factory output numbers for the
motor are 638 horsepower and 604 lb-ft of torque.
The engine retains its factory dry sump oiling system and is
equipped with a Lingenfelter pulley and ECU kit, custom headers,
and a full flow exhaust system. Spanky's Rod Shop custom fuel
injectors were installed, and a ZR1 fuel pump feeds a secondary
Aeromotive fuel pump. Cooling is provided by an oversized Be Cool
system, and a Spanky's Rod Shop wiring harness and cruise control
module are dealer serviceable as factory Corvette ZR1 electronics
with GM plugs.
A GM performance front axle with 3.73 gears and bearings has been
upgraded with Driveshaft Shop Level 5 half shafts and strengthened
main caps. The 4L80E 4-speed automatic transmission has been
strengthened and utilizes a Billet input shaft, performance shift
kit, TCI Maximizer torque converter, TCI forged flexplate, and
oversized transmission cooler.
Out back, a custom Dana 60 rear end features shot peened 3.73
R&P gearing, 35-spline axles, a Detroit Locker rear
differential rated for 1000+ horsepower applications, and Billet
aluminum main caps.
