We are awaiting a new shipment of late model castings from the foundry scheduled for the 2nd week of July. Shipments for the late model intakes will resume shortly after we receive the next batch of castings.

Fear not fellow Pontiac people.
The gentlemen handling this project are doing it for YOU, for the love of the hobby and are likely just recovering enough in funds to cover their expenses. A huge thanks to Tom and John. This project is truly a dream come true. |

Same here glad my payment made it, Skip. I worry about the USPS at times. My mother always said 'patience is a virtue ', the intake will be here sooner that later. I tease friends I'm getting a new bathtub shipped from California! They just look.

The past 2 years a number of my bills do not make it here or out when I pay them USPS. Our regular mail person is great but when she is off they have tossed the mail on the sidewalk by the back door of the office!

I was also glad to see my check made it. Not much faith in the USPS although my regular mailman is awesome. I recently debuted my ‘56 Chieftain at a car show and he recognized seeing it outside of my garage and introduced himself as a deliverer of parts.

Yes I just took closer look at your 56. Very Nice. I had a 55 blue and blue,1960 389,65 GTO heads,068 cam,4spd built hydro,4.30 gears. That hydro would almost knock the windows out when shifted at full throttle. I had no idea what I was building back in 68. Local John Labuda has a 56 gasser he takes around,he usually at Norwslk.

I'd just like to say these intakes are beautiful!
But I do have a question? I'm not much of a carb tuner, so hope this isn't a stupid question. Do you need to set up the rear carb different from the front carb because it sits higher on the intake? Or do you get a enough crossover or fuel mixing from the two carbs in the plenum area that is doesn't matter? Thanks |

If you set them up progressive you will run off the front of the rear carb and you wont ever know your driving a 2-4 setup.Will drive like a 2bbl.Tom

It is un like later EFI intakes, that have a single throttle body on the front of the intake that can cause air distribution issues with those intakes. At one time Joe Zajac, Larry Kauffman, and I added short stub stacks under the carb gasket to see if the carbs needed more signal strength. IT MADE NO DIFFERENCE in the performance of the intake on the quarter mile runs so the STUB STACKS were not used. This was using the 3rd Generation Randy Williams "V" intakes. Tom V.

Mike has a question:
On the original Factory bathtub Intake there was a "V" in the lower plenum with two offset raised ledges at the rear of the front carb. and one to the front of the rear carb. down on the valley floor that I presume would not allow the fuel from one carbs. cylinders to get into the other. What is to keep the fuel from going forward on deceleration and backward on acceleration without them? This ledge was necessary and tried and tested by Engineers and won races, yes? If I am correct a fix, if needed, is to add the ledge back in to this design, if it becomes necessary. You won't know until someone gets there's running and test and tuned. Secondly, since the "W" in the current Plenum divides the driver's side half cylinders 1,3,5,7 from 2,4,6,8the left side primaries and secondaries feed the left side only and the same on the right side. This I am very curious to see how well this works. This too is not what the Pontiac Pros designed into the original Bathtub Intake. I fear that you had the chance to duplicate the original to the letter. Why change a winning tested and proven design to begin with? What you have is an untested, unproven very expensive trial and error product that may not work as intended. Then again you could get lucky because you are an engineer as well, but I believe in those Pontiac Gurus that manufactured the original design because it is tried and we know it works. I saw this way back earlier in this post and I came up with a possible solution and I still stand by my theory, after all as long as your changing things why not experiment with it. I am waiting to hear from the new owners on how well the changed design works. Good luck. Last edited by TRADERMIKE 2012; 06-30-2022 at 05:05 AM. |

Mike,please do your self a favor and search the internet to see what fuel in a running engine looks like!I believe John Kasse(spelling) had a intake with a clear top.When the engine is running at RPMs it is just a cloud of atomized fuel and air.You dont see any fuel.Engine at idle is where puddling can acure.I have owned just about every Bathtub since 1963,raced the factory ones and had to build the dam as John said.The Johnson Zajac was a big improvement over the factory.Rand Williams made many diff plenums,I actually test 3 of them for him with a 461 E headed engine and there was about 5 HP diff between the 3.His latest and one I did not get to test is the W plenum which I used to reproduce.I have a Johnson on my 63 434 Tempest and the Williams W plenum on my 62 434 GP.Both have factory 750 421 SD NASCAR AFBs.The Tempest has way more cam and better heads than the 62 so they drive diff.Both are running progressive off the front 2 bbl of the rear carb.They both drive better on the street than the BEST running tripower you will ever drive,more like driving a 428 2 bbl engine.No lugging,nothing but good smooth throttle.I drive the 62 every Saturday to a show and am amazed how well it drives.My 62 has 2.68 rear gears,I can shift from 3rd to 4th and end up at 1200 RPMs driving down a city street and it just pulls with no bog or hesitation.The factory intake was done back in 1962,they did well but no comparison to the W design.Break out some dollars and get one and try it for yourself.Tom
