My brother used to be friends with the owner as far as I can tell. I haven't read the ad fully yet, but I remember my brother telling me the original block let go at 440rwkw on the dyno

Last I heard he had the DART on order, and there was a 6 month wait... but the list of other parts he had was very impressive. I thought he was aiming for 1200hp, looks like he never got there
The dude was a fabricator/welder by trade, he did some sick as extractors for a sprint car worth $2500 that I had pics of, I'll see if i can dig them up.
