Car was a 3 year project which grew out of control very quickly.
What started as a paint job, grew to an engine swap, then a full on restoration.

By the time I was done, everything but the dash wiring was removed from the car.

Overall I'm very happy with the result. I won best modified in the 90-99 class at The Cabelas car show, which had approx 1500 entrants. On the 90mi ride there I got over 20mpg at 75-80mph.

Better than anything is the performance... I now have an 11sec car with incredible handling/stopping power, that I can drive anywhere. It started with 190hp & became a car that now buries the 140mph speedometer in 4th gear. Every bit of the car was built/assembled by myself with the only part being partially farmed out was the paint at my friends shop. I participated in every aspect of this as well, since I had previous experience working at a body shop. I just did not have a spray booth to achieve the quality of paint work that I desired at home, so I had to get some outside help.

Here is the link to the original build thread.

It evolved from my summer driver to a complete resto-mod style project over the 12+ years I have owned it.
I went in blind & gained a lot of knowledge with respect to LSx engine swaps & the nuances of the 3rd gen platform.
Thanks to all for the advice & tech help over the course of the project.
