Inliners International Forums General Discussion Hi Performance New 2 BBL intake on the horizon!

Not like I have any questions or anything--- but which 2bbl, small or large base? Will it bolt to the stock exhaust manifold? Is the first book out for purchase, the one with a 56 Chevy on the cover? If so please tell me where to get it. Thanks. Jay6155

Jay the first book is getting closer to completion. I just need to visit the machine shop for some last bit of photography needing to be done there, and then its can be sent to the printer.

The intake can be used with the stock exhaust, but not in the sense it will bolt to it as the factory intake does, but it will have its own separate heat box which will require a plate to be bolted to it to plumb in water to heat it, and it will be provided with the intake. The Rochester 2GC carbs with the 1.250" throttle bore size is the one that is intended for use on this intake.

Thanks for letting me know. The stovebolt is an interesting engine . I grew up right on the tail end of their use. Saw a lot of them in junkyards when I was 12 or so. Didn't know really what I was looking at at the time. Funny how one learns to appereate things later on. Looking forward to both. Jay6155

Can you make an intake to mount 2 1 barrel GM TBI s on a. GMC 270 H head, without having to use adapter plates. Would also like to have the horn mount cast in, with bosses for Vacuum port for hydro vac brake line as well. I know you can, but will you? this is for a 1950 GMC 3 ton fire truck, I want to go faster. You don't have to divide the ports or make them equal length.:)

I am planning both a few Stovebolt and GMC intakes. Which GM TBI are you referring to?

Single barrel TBI off an 88 Cutlus and 90 Grand Am. Bill at Hamilton Fuel injection has done this , I just can't find an intake yet. Thanks

If you can send me a gasket to verify the correct pattern i'll see what I can do. Thanks

Will pickup gaskets this week. Thanks

CNC-Dude, still interested in that manifold. I got sucked into an out of state job that I wasn't expecting. Had to drop everything and run. Will pick up gaskets tommorow. I'm getting the wiring sorted out on the 2 barrel TBI, hope to try starting it with that on it this week. Thanks. Jim

I actually have become involved pretty heavily in the last month or so with some TBI projects both for the GM 1 and 2 bbls. as well as multiple TBI setups, so I have all the dimensions I need now for both sizes of the 2 bbl. units.

finding good street intakes for the Chevy 153 isn't easy how bout a 153 4 intake that takes a good 2 barrel ?

I have some products for these engines as well already in the works.

Any news on the new intakes? Got my GMC 270 running and driving on the single 2 barrel TBI. Was wondering about the dual 1 barrel manifold. Thanks Jim

I'd love to see some turning vanes incorporated in the elbows of your intake. lots of turbulence in a square corner for air flow.

Do a search on turning vanes in elbows etc.

Here is a good way to get ideas for turning vanes

Are you taking into account the shape of the moving air mass in a given cross section of a runner. example - a square or rectangular runner does not have a rectangular column of air flowing thru it. The air flow in the corners is at a reduced rate there for reducing the volume flow (efficiency). Oval or round runners tend to have better flow characteristics in a given cross sectional area. Also bends need to have a larger cross section to maintain the same flow rate.
Looking forward to seeing the finished version of the 4bbl manifold.

I do not think this is true. The bend needs a LARGER FLATTENED SHAPE ON THE SHORT SIDE RADIUS but a reduced cross section to keep the airflow "glued in" to the short side radius wall.

Build it in clear plastic so you can watch the flow.

He's a retired Ford engineer, i'm sure he's done it many times.

Done what? many times. Any news. The 10000 lb GMC 450 with a 270 H head now tops out at 60 mph running a 2 barrel TBI with dual Fentons. Interested in the dual one barrel manifold still. Jim . Thanks
