I had a 90 lx with a 342 in it. It had all the bolt ons you could put on the motor. I had the stock suspention on the car also. I went a best of 12.20 @111 with a 60ft time of 1.75. If I had some decent suspention on the car it would have gone 11.90`s. That was on a track that was at 2800 ft. above sea level.
