[750hp]

Spook, you're spot on about Mark. He has an adjustable power steering setup on his car, which I saw in action when he turned up to a club breakfast a few months ago.
It's a genuinely fast car with a stout high-rpm small block and sequential Holinger trans, and I wouldn't be surprised if Mark has shouted from the rooftops that it is the fastest Cobra in the universe. He is not a shy man.

For the life of me, I can't recall the name of the steering assembly, but I recall it was used by most sprint car drivers. Might be worth looking at Boettcher Race Parts to see what they offer.
