I don't agree. Cross rams are an issue with carbs but with the port injection like I did in the pics, the manifold just flows air and the engines start and run just as good as if it had a 4 barrel. Driveabilty was excellent. Conversion cost is time and materials. The last one I did was right at $3K. The major part of the work was mounting the injectors without fuel rails to hold them down. I made custom clamps that did the job. The 90 degree AN line to injector fittings are also very pricey.

I think we said the same thing. Cross ram with carbs not a good idea for a street car but if a person is willing to spend a few thousand for an EFI conversion then it works.

this topic perks my interest because, i believe, it would also pertain to a max wedge cross ram ?
as i have said manifold, carbs, linkage, and heads, i have entertained trying this manifold on my charger eventually, using throttle body injectors.
the engine i have is a semi serious piece with cam and compression [ported RPM's] and i also have a converter and gears [which can be changed]
the fuel system [not installed as of yet] will consist of an in-tank aeromotive 340lph pump with a 1/2" return, a new stainless tank, and as of now, a 3/8" suction.
is this an idea i should dump, not cutting the intake apart for individual injectors ?
thoughts and criticisms welcome please.
