1990 Chevrolet Silverado 1500 Silverado Description

1990 Chevy C1500 Truck heavily modified

LSX Motor:

408ci stroked LQ4 shortblock from Livernoismotorsports.com dished piston low compression 9.7:1 for blower setup which I did not install.

317 LQ4 heads level 3 ported by Lloyd Elliott elliotsportworks.com with valve spring upgrade for the camshaft.

Comp cams 54-477-11 227/243 duration @.050 .614/.624 114 LSA camshaft. comp cams blower grind.

Comp cams 3/8" .080 wall pushrods

Intake is mirror black powdercoated procomp qualifier intake ported to match 102mm throttle body.

48lb/hr racetronix flow matched injectors and Walbro 255lph fuel pump.

Engine makes 600FWHP and 600lbs of torque (479hp 474tq at rear wheels on Mustang Chassis Dyno) and just over 1000 miles on engine. Driven just enough to get motor broke in for dyno testing. Easily capable of 1000hp at flywheel with a supercharger which was the original goal but decided to build something else instead.

Transmission is heavy duty 4L80E with 2200 rpm stall converter.

Rearend is from a 1990 454 SS which is a 14 bolt 9.5" with 3.73 gears and upgraded detroit locker true trac posi unit.

transmission and rearend choice was primarily for this motor being supercharged which I did not do but there if you decide to take this thing further.

Wheels are staggered 18" Boss 338's 8" front and 9.5" rears. Some places list them as 8.5 and 10"

New 255/45R18 tires on front and the rear 305/45R18 nitto drag radials have about 13,000 miles on them.

Suspension: 4" drop springs on rear and front is lowered with 3" DJM Control arms. Shocks are Edelbrock IAS performance shocks and front sway bar is the Belltech 5404 1-3/8" thick. Also, I changed the front springs to progressive rate Eibach springs.

Truck runs very strong yet very streetable and gets good fuel mileage. Dash is still the original dash.But all the other interior and gauges have been replaced. Cab was lined with .080" dynomat. Frame was cleaned and painted as well as rearend and front suspension. This is a very clean rust free truck.

Bed is epoxy lined, not rhino lined but similar. not as thick and heavy. With rubber mat on floor of bed and a pace edwards roll top bed cover on top. radio antenna and stake holes in bed were all welded up and shaved when truck was painted.
