I am in the middle of design on a billet, low profile version that will use LS style throttle body. There will be two versions, low profile for boosted applications and a mid rise version with runner length, taper and size that is appropriate for 420" ish engines making peak numbers between 7000 and 7500. Flow designed using CFD (Computational Flow Diagnostics) within Solidworks 3d software.

I'm surprised that there is such a lack of manifold choices at this point for Gen 3. Will see if made in the USA is even possible, but making no commitment to that for now. Will be very nice and not $4800 like the other billet offering.

Not trying to hijack Steves post. I believe the more choices the better for these engines. They are the future of our Mopar hot rods.
