This was the car/engine that I saw in the works when I was at Kirkham last year.
I don't know exactly what's going on under the hood manifold wise (I did see the the Paxton bracketry they developed for the SOHC) but I do know a couple things:
Super Snakes (the actual Paxton layout) never seems to be the same. Sometimes the pair sit higher, lower, closer together, further away from the block, etc.
...and...
The clearance you need on top of the manifold depends on if you went with the Edelbrock FX-66 or Dove dual inline (which doesn't sit 'high'). The issue with the carb hats is that they flare out.
My build has a twin Paxton but it's not necessarily (at all, really) a Super Snake replica. I didn't intend to go there. I'm keeping my options open for the hood. I know a lot of folks don't like it but I wouldn't kick it out of my garage.
I think they did an awesome job and I want to meet that crazy owner.
