let me explain my screen name, and introduce myself.

Hey 'defiler', welcome to FABO from SoCal. You're going to have fun here.
You're always going to have the uber-purists let you know when something isn't as they believe it should be. But I figure it's your money and your car, so build it the way you want. The easiest way to quiet the purists a bit (you'll never shut them up) is to tell them whatever it is they're spouting off about is something "custom" rather than GM or Ford or whatever.
For instance, my '69 Dart engine block is going to be painted a "custom" shade of blue because I like the color and it's going to 'pop' well against the Viper Red engine bay, and I'm seriously thinking about a "custom-built" overdrive tranny because it will fit without cutting the existing A-body tunnel.
Again, welcome to FABO. Post pics of your build as you go.
