Does anyone know whatever became of Ron and that badazz 500" SB Dart of his?

I was looking for it in the tech archives I couldn't find anything. I think (I don't rememeber exactly) it was a Siamese R3 block and it was like 4.22" Bore and a rifle drilled 4.5" stroke crank.

I remembered we ran the exact same Bullet cam lobes/Grind in his 501" small block and my 517" big block.
