some Photos of the Viper Intake project.
The transition between the two ports will work on the older heads but it's too much for the square ports. for the 6.1 style port the whole manifold would have to be redesigned from scratch, but the good news is I'll have a working model to copy off of if the market is there.

Obviously there is a lot more to be done, I'm hoping in about 3 months I'll have a working intake.

Matt I didn't forget about the P7 manifold, it works well with the 03-08 heads but it's too different to be useable with the Square ports, problem is BIG Intake company doesn't think there's enough of a market for it.
for the Square port heads I'm working off of a modified parker 351C intake...heavily Modified,
