Yes, 2v Holley pattern for the moment. A 4v is down the road.
We haven't had problems with the intakes. The thing is that we aren't duplicating the original one. This is a stock looking, but full of subtle improvements, based on the lessons learned from road racing it for 30 years. The original intake is really good, so nothing drastical. I can tell you for those that live on cold areas, that it will be water heated, but the core can be either removed or disabled very easily.
While a lot of fun and learning, this project is very time consuming. It takes a lot of time and financial effort to gather the expertise and abilities from the guys that make the inline sixes scream on the road racing tracks, to develop a killer package for the street. We have some local legends and big names helping us out. From the killer head al heads, to the bank vault strong pistons, to the TC purebred rocker arms.
