Once I realized how it was done I had ideas on doing a build with a elco and a stock 4.3 S10 engine/trans. I have too many project ideas however.
The TBSS wheel base is 113", G-body El Camino wheel base is 117". Adding 4" to the frame is pretty easy; but taking out 5" to fit a regular G-body isn't. The TBSS chassis is very robust - but you would most likely have to channel the body over the frame. The TBSS has front/rear track width of 62.8"/62" and the Elky has a front/rear track width of 58.5″/58.8″ - so it is pretty close. For the cost of a clean TBSS with a blown LS2, I'd venture into a project like this.
