I've had an Arnst/Butler and a Superformance Cobra. Both great cars. Both had modified seats, but the Superformance was the only comfortable one to sit in at 6'5" tall. Also had more foot box room.
11.11 @ 128 on street tires was a lot of fun, but for some reason I didn't keep either car very long. My wife says I look embarrassed when I was driving it, like I didn't want all the attention they bring. That could be.
I sat in a friends 66 427 roadster Vette. That had less room than my Cobra lol. No head room at all, and the seat didn't go nearly far enough back for me. Not sure how big and tall you are but you need to get in one of these cars first and make sure you fit.
