After all the work I've put into this car I've lost interest so it time to move on. It's a 87 GN with a fresh rebuilt 5.3 with a 76mm turbo. The car has roughly 98xxx miles and about 500 since the swap. The body is solid and straight but could use repainting and it does need new front and rear bumper fillers. The interior is is great shape.

Details on the swap
03 5.3 completely rebuilt arp main and head studs arp 2000 rod bolts. 241 heads, Brian Tooley stage 2 turbo cam hardened pushrods and dual springs. Edelbrock pro flo intake. The turbo is a magnum 76mm ball bearing. Precision 46 wastegate. The hotside is flipped truck manifolds with a custom crossover that I built. It has a 33x12x4 a2a front mount intercooler. The trans is a stock f body t56 with a monster single disk rated at 875 fwhp.

This has been a fun car to build but it's time for me to move on to something else. I'm asking $14000 but am willing to negotiate on price. Not really interested in any trades unless to a 99 or newer corvette. The car is located in central KY

I've taken some pics of the only rusty/bad spots on the car. These pics really highlight the bad spots and make them look worse that they really are.

No I still have the car. Its currently getting twin s366 turbos all with a custom hot and cold side and a new 58x short block. I hope for the car to be done before summers end but don't really see it happening as of right now. I would consider selling the car for the right price but honestly I don't know what that number would be.
 
Not exactly. I was swapping some better heads onto the old motor when I discovered some pretty severe scoring in several cylinders I'm guessing from not having a air filter on the car. So I found a deal on this short block and just switched them out.
