briefly it has 140000 miles but the mtr was rebuilt many mile ago, 0,000? (I need to look up) by Lingenfelter Engineering. Look at their web site. It is an LT1 built to be a 383 with LT4 heads intake manifold, hrottle body and a bunchmore. It cost about 15k by the time I was done with the motor. 457 HP and 450 ft-lbs torque. I have not raced it but know in my heart and my butt that it will do 12s quarter miles. I did take the car to Atcoone night when the mtr was stock and she did exactly what the book said. 13.9 at 101mph. Why did I do it? because I wanted to, hat's all. I also ran across a brand new ZF 6 speed for a song and put it in. It is for a 95 vette I think and has the crash through gate for reverse instead of the ring you lift up.check out http://www.lingenfelter.com/engine-packages/c4-lt1-lt4-1992-1996/383-cid-lt1-lt4I had my own mechanic put the motor in so I just got the crate motor as described here. My exhaust is by B&B, tainless and sounds awesome.
