I have seen a smaller version of that motor on a sand rail. Billet block and heads V6 with twins made 1500 hp and it had a lot more in it.
It was artwork.
Well that was at Kenny Duttweilers shop a couple of years ago now.
I am not sure of it but my guess is that the block and heads are from Alan Johnson Racing.
The guy in the video says the same thing but that motor is bigger than the one I saw a couple of years ago. 540 cubic inch V6 is frikkin awesome.
I would love to put that in a Buick just once. It would tear the car in half but it would be worth it.
I wonder how many castings they made? It is not a billet block, so how many did they do? Kinda crazy to cast a one-off block, but I think it ended up in the Middle East where sometimes cost is not an issue. Still........you would think they would have made at least 10 parts for backup. I use to build WWII Rolls Royce Griffons, and we had 12 complete engines and a handful still in crates for backups. This was for an Unlimited Hydroplane race team.
