David (kountzecobra) asked to see pictures of the engine I went to see in San Antnio yesterday. I thought the rest of you would like to see it, along with the car in the background...
The engine on the stand is a Shelby block stroked to 482ci with aluminum SOHC (Cammer) heads. The others are Cast Cammers. They are all using custom ground cams and roller rockers from Rocker Arm specialties. I don't know the horsepower but suffice it to say, it is well over a briggs and stratton.

The car int he background is a true GT500 with only 2000 miles on it... 1/4 mile at a time
The rockers and chains are all just on there for the pictures, not yet setup

No- I won't be using the Hillborn... but it will be injected
This is the engine that I watched run on the engine
stand. It barely idled at 1300 rpm... the custom cams are something else (look at the lobes)! Watching it rap to 7500 rpm was incredible (and faster than I have ever heard). It acted like it could go to 10K no problem! not that i want to try that..

Yes, they are the rare aluminum heads. Great when used with the Shelby block!
A little trivia... The full iron cammer weighs 618 lbs and the aluminum version on the stand weigh 480lbs. -
There are more pictures in the pages of my gallery.
