That's a fabulous setup, Brent. I think your customer got a great deal on the price too, for what it's worth.
I love reading about these types of build or watching the dyno videos on the interweb but you don't often get to know what the customer paid for a given setup.
I would be seriously tempted to buy a 550 HP Clevor (say, a 427 ci) when the time comes to get my Cobra project underway. I wonder how much that would cost...
