Gentlemen,
I have been looking for the pictures I took at the Gardena Shelby tire warehouse/engine factory this past summer. I've found two other shots in my stack of photos. These came from a couple of pallets of Buddy Bar big block castings and show two shots of the water inter cooled s'charged engine with aluminum heads and fuel injection. A version of this block was being tested on a dyno when I was there for SAAC 27 this past summer. I heard, but did not see, that the 1500 HP was achievable from this block. but, not being particularly interested in an engine like that, didn't look for more detail.
So this isn't the complete answer that you are probably looking for, but should be another piece of the puzzle. I do remember that this engine was being compared with NASCAR motors, the way they'd like them to be, not the way they are. Still 1500+HP is so much overkill for a curved roadcourse that it must only be for those wanting to drag race.

Anyway, if you have way over $30K and want the Shelby name all over your engine, give them a call at the website above and ask them what'll take to get you 1500 horses!
Enjoy these pictures !
All the best,
