Brett, Welcome to the site. The El Camino is a great vehicle, is it a car or a truck? Much debate about this subject. I have owned a 78 SS as well as a 81 Royal Knight El Camino, both were great cars. Use it as a car or haul stuff like a truck, plus it can be made to perform very well.
Check out Herbs (Yelcamino) 66 El Camino on here, I saw it in action at RTTH IV, it is a very well put together machine plus it performed well in autocross and at the drags. Good Luck with your project.
