Killer small block build

I believe it. Because I've seen something very similar locally here. There's a local engine builder. Genius guy. Built a 440 small block. 780 horse before any tuning. He figures he can put it to 820 with a great tune. I imagine he got more out of it cause he used a solid cam. He's VERY tight lipped about it. But from what I know it's an R3 Ritter aluminum block. Indy heads (even though the builder recommended going W heads and figures he could have gotten up to another 50 horse with them, I guess the guy had indy heads already). And lots and lots of excellent work. Best part? 400lbs.

I will say. I am unsure of what compression/gas it runs on. But trust me. Getting close to 2hp per cube is possible to achieve on mopar small blocks.
