[nsb29]

I picked this mother up about six years ago when I started The build it came from a Pontiac G8 an LS two with a sixL 80 E transmission 60 k miles $3500 shipped to my door from an outfit out of New York that primarily specialize in Corvettes The rest of the money was spent on having the ECM Flashed bye a place in So Florida Don’t remember their name right now A pair of electric fans and some other miscellaneous stuff like motor mounts, driveshaft I did End up buying a harness so really probably closer to 5500
