What an incredible build you're doing. Build? It's more like a work of art! Fwiw I borrowed the 427 CSX once owned by Tony Hogg of R&T from an
owner before he had it, my friend Mike Clark of Altoona, Pa., for photography in Georgano's book "A History of Sports Cars". I drove it for a week and will never forget that.
I recall getting onto the Pennsylvania Turnpike at Bedford and as I nailed it and flew past an 18-wheeler, the driver gave me a big wind-it-up sign with his arm and blasted his horns.
Attached is one of the many cars I should have kept from those years.
