Hi Cory,
I'm into scratch building cars and am glad to see when others are also taking that journey. It sounds like you have some relevant background for this. I've heard an estimate that it takes at least 5,000 to 6,000 hours to complete a scratch built car. The first one I did is a Ferrari 250 GTO and it took 20+ years to complete and I have no idea for the hours because I didn't track. I'm in the middle of scratch building a Lamborghini Miura SV now and I'd estimate it will take less years (I'm retired now) but more time than the GTO.
I do know Chuck (haven't talked to him in a few years though) and saw him build his scratch built Daytona Coupe. I don't know about the Cobra plans but Chuck is a very knowledgeable guy and does know Cobras from his experience with an original 427 that he still owns. I used him as an advisor early on in the planning stages of my GTO build. I'm not sure how active he is these days but that just could be because we haven't crossed paths recently.
The build thread for my GTO project is here:
