I guess I will stay with the stock front end for now and spend the 2000.00 on paint.
I hate to throw you off your origional plans (it is your vehicle), but I would try mocking up a set of mounts on the origional frame rails and see how she fits. Were you able to get any mount info from the guy that did the '63?
I have looked and found no conversion kit for the swap. Would a set of FORD installation drawings help you with the engine mount design?
The only thing I see right off-hand that will interfere with the installation will be the heater box/motor on the right apron. A guy did a '56 with a 460 and I will try to see how he got around that problem.
Were you able to keep the cooling module (rad/fans) from the MARK?
And please put this on a project page so others can see how you solve the problems with the swap.
