Hello CSX, I sent you a PM about the 427 chassis plans. I just finished building a 427 from the plans and do not need the prints anymore.
If I was gonna build another 427 I would buy a finished chassis from one of the vendors and save a lot of time and money. I would start with Acton Custom, Nick knows more than most about building a Cobra from scratch.
this is what it looks like ready for a alum body.
regards, karl
