280zx With V8 Swap

Built this car myself 2 years ago. Married now and need the money to pay the bills. Started out with a rolling chassis no engine no transmission. Pictures are current. The engine is a 1995 5.7L Chevy Small Block "lt1." The transmission is a 1986 T5 borg warner transmission. Car starts and drives. Listed below is everything new/changed. I've got 12,000 dollars into this car... I'm asking 5,000. If you can give me a good reason I'm willing to negotiate the price. Car will need to be towed since its not registered. Transmission may need a little adjustment in the future. Any other questions feel free to ask.
