This is a 1990 ZR1 with only 12,60 miles it is NOT STOCK it has over 22K in preformance and body upgrades.
I has the Callaway areo body rear bumper and has 1996 corvette front bumper & fenders.
The heads were sent back to Greg Vandeviter of GM MERCUISER ( the people who built the motor for GM)
The heads were ported & polised & biger valves were put in. The injector housings were match ported to the heads. The air plenumn was match ported to the heads as welll.
The Throttle body was ported and match ported polished air housing
the car has forced air induction
Screamin deamin coil packs
8MM new plug wires
Custom computer chip was burned on the dyno
Car Dyno tested at OVER 500 HP at the rear wheels
Valve covers & Air plenumn was powder coated RED to match the car with Black letters
Many of the parts on the motor have been polished
411 gears
Polised porcelain coated long tube headers with 21/2 Borla exhaust
Porcelain Clutch
OZ RACING WHEELS with brand new tires 275/17 on front & 315/17 on the back
The Interior in Black and everything is in mint condition from the seats to the carpet
The car used to be black and I had it paited Red with black accents - black lettering,black mirrors,blacklouvers
Paint is a 9 out of 10 looks great
all the rubber molding are like new
I have owned the car sense 1997 and hate to see it go
The only known problems Has a small oil leak coming from the front of the motor (it just drips a little when it has been sitting for a while)
Scratch on the passenger side window
I put to much wieght on the steering wheel when I was getting out and the steering column tilt moves a little but drives perfect
THAT IS IT EVERYTHING ELSE IS GREAT
The car is for sale locally so I reserve the right to end this action at any time





Personally I think it has 500 @ the crank. Opinions?
