Guy around here has a set of kre d ports drilled for the early intake pattern, but don't think he has any plans of using them.

Tom, it would be so sweet if when the intake was digitally scanned that the runner area above the flange were raised for taller port heads

OPH,the ONLY way im going to do this deal is IF I can find the original molds so what you are thinking WONT happen if im involved.Tom

I am thinking most with the taller ports will just have to tig some material on top of the flange.

Sorry Tom, wishing you only the best in coming up with the molds.

I had to do this to the repop RAIV , two Torker IIs I use (one on the 78 TA now one on the 455 Stump Puller motor for the 81 TA on the engine stand)and a Tomahawk I wanted to try for either KRE or the SD ported heads. Not a big deal. Will just need a clean up mill afterwards.

Keep in mind that the entire intake port is raised up by .250" on a '64 and earlier head compared to the '65 and laterD-port heads. The intake bolt pattern is exactly the same with the exception of the two bolts at the front water crossover between early and late heads.

You might still need to add some material for a really tall port, but you're already ahead of the game by a full quarter inch. Adding material to extend the port floor downward will likely be the issue moreso than the port roof.

Bart,Randy intakes were designed for the late heads.Nothing will be needed unless taller port is needed.Tom

[JSchmitz]

I have a TIG welder. I can add material to a manifold easy.

I'm interested in one as well. Was planning on using my Doug Nash tunnel ram on our '61 Catalina, but if I've got an opportunity to get a Bathtub then that's even better. To me it's the best looking intake Pontiac ever made!

Agree. On a full size Pontiac from the SD period, It has that really serious factory race car look. Even if not up to current state of the art performance levels, if not running a specific class, classic factory looking SD parts are a winner.

[slowbird]

Im kind of surprised no one has recast it in large quantities. Its one of the coolest Pontiac intakes ever made. I can't imagine it wouldn't sell. The alum tri-power that's now available seems to sell decent why wouldn't a recast bathtub?

[tom s]

Just like the inexpensive iron pontiac block.ROI is just not there.If I can get my hands on the molds I will get maybe a dz done.At that rate the cost for casting and machine work is high.If you could run a 100 or so at one time it would come down but you have a lot of money tied up.If you make a serious biz then the product liability insurance comes into play along with the prop 65 BS we go thur here.If you sent the molds to China and did a bunch the cost would come down even more but quantity would have to go up and then a whrse to store them,package and ship.Baby steps at this time.Tom

Agree with Tom on this one. IMO, a "large run" would be about 50 manifolds. It would probably take a few years to move that many. If you really think about it. How many Pontiac people are left out there willing to invest $4000.00-4200.00 on an induction system? My numbers come from Tom's projected $2000.00 for the manifold, the cost of 2 proper carburetors, linkage, air cleaners, fuel lines, water neck. It would all add up pretty quickly. Honestly don't know if there are 50 Pontiac fanatics willing to do this. Although it would fit a GTO, the primary market is pre-1964 full size cars. Not allot of them left.

Running Nostalgia Super Stock in a Pontiac only leaves you with a few choices for intake and carbs. Either a Single AFB, 2x4 intake with AFB/Edelbrocks or Tri Power with Rochesters. Not a lot of intake choices for the 2x4 guys. I run a Wenzler and with the amount of work it took to get it to fit, welding up all the porosity holes, 1/2lb of Moroso A/B Epoxy, Making a top plate, hours of port work, I think a bathtub would be worth it. Even better if it had a GM part number on it.

Using Tom's 2K, add a couple 750 E-carbs, I think you could put something together around 3K.

With Nostalgia Races getting bigger I think you could move a few. Plus this thread has already had 3K+ views. (Maybe its just me and Tom that keep clicking on it)

What about casting without the water cross over?

Does anyone know the height or could measure from sitting on a bench to the carb mounting? I think if it is shorter than the Wenzler/Nash set ups then that open up a lot more people that may be interested as they can run a stock GTO hood.

[mgarblik]

I think making this manifold is a super cool idea. Not trying to talk it down in any way. I want one! Just personally don't think there is a market for 100+ of them. But I have certainly been wrong plenty of times. Not a deal breaker, but I would certainly prefer mine with a water crossover. If you don't want one. Hack saw it off. Much easier to remove it than try to cobble one on a manifold that doesn't have it.

Some pics and height measurements.









Checking carb pad height in relation to the valve cover rail.

[Mike Davis]

Thanks Bart.

It looks to be approx. 1 inch shorter than a Wenzler.

Mike I think you could sell 40-50 of these within a reasonable time. 100 I am not sure about. I would take 2 (one for current engine and one for back up on the stand.

I know 4 NSS guys that would buy now. as they are either running a Wenzler or Offy. This just looks much better.

[Ducks Goat]

I wonder if the guys at Fabcraft would have any interest in investing in this deal since they make a lot of other SD stuff?

[tom s]

No advantage to cast without the X over as whatever valve angle you cast for it will require a lot of work to port match.As I said,there will be a lot more sales for late water pattern.Wish I felt confident as the board!Tom
