From the videos is seems that there will be different phases to this project, as in a 4 bbl after the 2 bbl testing is done.
Servedio also stated that he wasn't sure if Vizard would use his heads or not. This tells me that at least Vizard (and maybe others) will have cylinder heads of their own to test/use on the project.
Wow their putting a lot of work into this, 318hp should no problem to keep the name mission impossible the might need to be bumped to 400+hp, I hope they also do 4bbl and headers along with a 2bbl and manifolds.
