I am in Plano.
I know a few good local chassis shops. One that is very good and reasonable for his quality is in Rockwall. If you alreday have bought a Jegster and it is in the car, he can do quite a lot at making it better.
If you haven't bought anyoone's kit and are planning on buying a kit and having a chassis shop to fit and weld it all together, I will suggest to just talk with a few chassis shops about installing a pre made kit and about buinding one from scratch. You may be surprised.
Will be happy to talk with you about an engine. Best time to call is at night.

Sometimes during the day I hear the phone or can talk but usually am very busy.
