Saw it at the Heritage day in Silverton. Not sure what mechanicals it has, but I think it is running a V8 Lexus with the auto box. It is so quiet that when he drove past me, I could hardly hear it idle.
Sounds brilliant when he revs it though.
I love the attention to detail, but personally I feel it was sacrilege to use an oval (if it really is one) for that purpose. He obviously spent a lot of money on the car, but I would have rather restored the oval, since you are spending a big amount of money in any case. My 2c.
Lovely vehicle nonetheless.
The only substitute for cubic inches are more cubic inches.
