Its been a while since I looked at one but I believe from about the 'vette cowl back to the 'kick-up' the frame is two straight parallel tubes. Wheel base is a bit short for something as tall as a COE, but if you extend it a bit using somethng lighter than the COE frame you could end up with a frame that made us of the 'vette suspension and was long enough for the COE.
The 'vette frame is not designed to take a 235 so you'll need some modifications to make it work.
The COE frame is designed tall and its a lot of thick steel designed to carry a heavy load. That truck is rated at 16,000 pounds. Empty your COE weighs a couple thousand pounds more than the Corvette and reducing that weight will make that suspension work much better.
Make sure you post pictures of this project somewhere. I'd like to watch the project as you proceed.
