      Pontiac 455 EFI inatake manifolds

      Hi All,

      I've been looking for some time now to change to efi...are there any ITB type manifolds for Pontiac engines or am I limited to converting a standard carb manifold? Another option would be to go with something like a Hogan intake but I would really like to have that 8 trumpet look going.

      Thanks!

      Edelbrock does offer the Victor with EFI bungs. As far as off the shelve EFI intakes for classsic Pontiac motors, thats the only one I know of. If your application needs a different type of intake, youre on your own. Converting an intake isnt really a big deal. 8 fuel injector bungs welded in and working out the fuel rails. Or, you can have it done by someone like Wilsons.
      I had Wilsons convert my Pontiac Victor intake to EFI before they were available directly from Edelbrock. Not using it anymore because I moved to CV-1 heads and they require a custom symmetrical intake manifold.

      Yes, Edelbrock is offering the Victor and Super Victor off the shelf Pontiac EFI Manifold. How ever Pacific Performance is offering the Crosswind and Tomahawk Manifolds with EFI bungs and fuel rails.

      I think he is talking about an intake like this, an individual throttle body intake. This is on a Can-Am car. Unfortunately it is on a SBO I believe and probably extremely rare.

      These guys advertise one: http://www.kinsler.com/page--Home-Page--13.html

      IIRC, there is someone on the PY board that was in the process of making some.

      I've been thinking about using the Professional Products port injection system. http://www.professional-products.com/EFI_2.php

      Nice thing about the Butler setup is that they have some base maps that will get you going pretty good right off the bat. They also dress (port/cleanup)the manifolds some before going out the door, makes a difference/saves time.

      PPR markets the PP PowerJection II at probably the best price, though the PowerJection III is about to be released. Obviously, this system is based on the Tomahawk intake.

      Edelbrock is getting ready to sell a kit for the Pontiac, based on the 2 EFi intakes they have. They use a branded MoTec ECU if my memory serves me correctly.

      Kinsler will build anything, though as stated, you pay. 20k is steep for just a 'wow-factor'.

      You could look at Marren, they do custom stuff too, much more reasonably priced, just as good if not better work. ( injector.com ) All you would basically need is to use a chebby setup and adapt a Pontiac flange.

      there's lots more then just adapting a pontiac flange to fit a sbc intake to a pontiac.
      i've always had a hard-on for exotic poncho intakes also.
      i converted a mickey thompson crossram to port efi with hidden rails and dual 4V efi TB's.
      consider using an older mechanical injection intake (u can find 'em on ebay every so often) and adapting it to fit your presumably late style heads, then make it efi.
      there's a british company selling ITB's with injectors built in, or add bungs to the intake.
      pontiac's easy to do cause of the valley cover being divorced from the intake, unlike a chevy.

      Thanks guys! That was exactly what I was looking for. Not too easy to get that type of intake on a Pontiac. I was thinking of doing something like the original Testarossa Ferraris, the stacks just flush with the hood with a plexiglass cover over that. Yeah, no air filter but I'm sure I can come up with something that can be put on for those long drives.

      Hi All,

      This past year I developed a IR manifold for Pontiac engines. I currently have an 8 stack setup using Weber 48 IDFs on DCI Motorsports Ram Air V heads. The engine produces about 700 HP. I compete in road racing events and recently ran the car at Laguna Seca. It performed very well.
      I am developing an 8 stack setup for stock D port Pontiac heads and will be offering these both with Weber carburetors as well as an EFI solution. These will be on my website early this Summer.

      I'm not familiar with the PY forum? This manifold was created fairly recently....I did the dwgs in early 2022 and this past year machined the molds for the runners and laid up the carbon fiber runners. Heres another shot prior to going on the engine.
