Seems they already have the Pro-flow EFI intake, so why not just make it a bit more readily available. Might give others like Fitech and Holley to offer AMC solutions at a better price point.
They seem to offer better intakes for other engines, but we are mostly stuck with 20-50 year old designs, I'm sure they would know what would work and sell best. |

Not much for EFI, but maybe in the future? My short list matches most others:
- 4150-style for universal-type throttle bodies or carburetor - injector ports to suit common injectors available in various flow ratings to suit wider range of power levels - stock-type accessory mounts - complete EFI kit, tunable like other aftermarket options, optional injector size - individual parts at reasonable, competitive prices (including bare, machined manifold) - common OEM sensors where suitable - kit to plug injector ports and unused sensor ports when fitting a carburetor (plugs can be removed later if fitting EFI) ... or offer less EFI machining (different part number) for carburetor use. Thanks, RD

Something like a holley hi ram - like they make for LS1.
Can run a single throttle body at the front, with a removable top to convert to tunnel ram. https://www.holley.com/products/intakes/hi-ram_manifolds/parts/300-122 |

Seeing as there is an array of existing products through them, Edelbrock should already have the complete universally agreeable answer to this question and that would most likely end their current line of carb'd AMC V8 manifolds to move everyone over to the next effective platform. In my case, an attempt to add MPFI to the AMC V8 would involve custom milling and the end product would be based on the Chrysler 4.7L system found under the hoods of G.Cherokees littering the yards. Yeah I can already hear the screaming and whining about how bad that idea is over all the mental gymnastics over alarm systems, body modules, emissions equipment, wiring and everything...Don't care. That is how I would make it happen and it would most likely involve a plenum for an 8-71 blower.

I like your thinking, but I think is would limit the market somewhat. Probably better to stick with a more universal 4 barrel configuration, you can always put a nice 90 deg hat on top for a modern style throttle body. I can’t see much demand for dual 4 barrels either, since injection would allow you to run a pretty big throttle body without compromising too much on low RPM performance. I’d even suggest killing off some of their carby manifolds if the new one let you run a carby as well as injection. People would buy that to have the upgrade path available to them over being stuck with a carby forever. |

I really doubt there will be a new manifold but a revised manifold based on an approved change. Edelbrock wanted 25k just to make the changes on their existing EFI manifold for a 4150 flange. I also would assume the changes have already been determined at this point. You have to remember the common sense approach just does not apply only the corporate channel does. So keeping the changes subtle and beneficial is key to Edelbrock. 1) 4150 flange (Benefit: increased sales) 2) Water at the rear of the manifold also on the drivers side (Benefit: eliminates potential problems with the Edelbrock head) 3) Allowing manifold to be ordered with out the bungs machined (Benefit: increased sales) 4) Increased runner size (Benefit: none) 5) Leaving additional stock on the out side of the runner in order for the customer to increase runner size. (Benefit: none)

The GM tuned port injection system may be the most widely produced fuel injection manifold system in the world. So why not an AMC lower intake that will accept GM-style upper TPI tubes? In fact, you could make a TPI-style lower intake to fit any manufacturer's block and heads, and make them to the specs that GM used for the upper intake. My idea's not rocket science. It's a proven system.
You can sell it as a full stand-alone EFI system. OR just sell the lower intake and fuel rails, and let the buyer "hot-rod" the system with the injectors and other pieces that best fits his/her plans. And someone will likely then make adapters tor all manner of 2-barrel carbs, such as Weber side drafts, even downdraft deuces, as Vic Sr. did in the early days. Four carb V8s still look trick as heck. Just build the lower to fit the GM upper... can't get much simpler. And that's what I would do. Not reinventing the wheel, just adapting it to fit multiple makes...including AMCs. |

Some great ideas here, if there were a single-plain, air-gap manifold that could be used with a carb, OR MPFI with a commonly available throttle body, I'd order one today. I'm one of few that would love a more elegant solution with a tunnel ram style efi intake with modern-style long runners, and a replaceable hats to accommodate dual carbs or a horizontal throttle-body. But I think that market would be very small. |

I like both the 4V 4150 flange and a 90 degree "hat" to adapt something like a Ford TB (what about DUAL TBs.. one in front, one in back!), and the GM TPI lower. TPI is old tech though, 85-92. Not so sure there would be much demand for that, though you could make different uppers for various carbs and throttle bodies. Don't think the TPI would be profitable enough. Instead of a 4150 flange there could be a larger opening with an adapter cover for different carb/TB applications, similar to what Clifford does with some of their six cylinder intakes (or used to...).
