Lawrence build his FFR to accommodate his 6' 4"(6' 5") 280 lb self. Placement of the seat, steering wheel and pedals are important. Sometimes you can move the tunnel over an inch or so to help with the pedal spread. Big guys and big shoes.
The length of your legs are a huge issue. Tall guys with short leg will fit into a Cobra a lot easier than long legged guys.
Last summer Lawrence check out a B&B for size and he fit.
Lawrence tried on Coach's Coupe for size but we had a very hard time getting him out. Almost called the fire dept. Now Lawrence is building a B&B Coupe to fit him.
I have a Lone Star. They are 4" longer in the cockpit. Doors are 4" longer.
A lot of long wheel base Cobras do not put the extra inches in the cockpit, so don't look at wheel base as the deciding factor.
