Baron, that’s what I’m looking to do with mine. I have a 65 421 block and heads that still needs to be built. Hopefully I will be able to fit air cleaners under the hood of my GTO with the bathtub. I think if Pontiac was going to do a 2x4 prototype test car the manifold would have been more of a low rise for hood clearance and air clearance. My idea is more of a home built day 2 street racer car. In other words, what if Pontiac offered the bathtub manifold over the counter for 65 and up heads. Anyone could buy it and put it on any car they wanted.

Tom, are there any more late intakes available?

[tom s]

Yes they are,machined to order.No more early availability.Tom

[tom s]

I think low 40s shipped.John has late castings available to machine.Could possibly be the last run.The foundry needs a large quantity to cast.Tom

[JSuchma]

Tom, when all is said and done, could give us a total breakdown of the early and late designs.

[tom s]

Will check with John.I think it was like 3-1 late to early.Tom

[JSuchma]

Thanks again Tom, without you and John this would just be a Pontiac dream!

[tom s]

Late style available!Tom

Just thought I would drop a note on here. I have driven my 62 Catalina with the new bathtub intake about 800 miles now. If anyone is on the fence with concerns about street manners, rest assured, this version of the bathtub has excellent street manners. My engine will idle at 1000 RPM's for as long as you like, rock solid, no loading up. I have been caught in construction traffic for 45 minutes at a time, smooth as silk. Off idle, very snappy. Tire shredding power at WOT. Draws quite a bit of attention at car shows. If you plan to run air cleaners, you can PM me about the fitment on a 62 at least. If you always wanted one, this may be your last chance. Super high quality piece. BTW, I have a pretty big solid lifter cam in my engine. 13.5" of vacuum at 1000 RPM. I am confident with a milder cam, this intake would idle right down to whatever speed you like.

I have one on my 63 Tempest 421SD North end of pits and car parked with Little Indians Sat. and racing on sunday.

John has 2 machined and ready to ship.One is already spoken for.Tom

This was/is an interesting project…kudos to you for taking it on and seeing it through.

Buddy of mine has a small foundry here in town( aluminum/bronze, no CI ) and I help him out every so often. Been a real learning experience with casting and all that’s involved, from idea to breaking a piece out.

Patterns can cost a fortune, and what pattern makers can do with wood, plastic, steel, and various other materials is impressive. 3D printers make cool things as well.

I’ve got a few things I’m going to try and mold/cast myself, should be interesting my pattern making ability.

[tom s]

I think John has 3 late casting ready for machined.No clue how long it will take to get another run done!At this time no plans to make another run of early intakes.Pm if interested.Tom

[tom s]

Sold out!

Hi all - new to site. I still have a 1974 GTO since college '84, which now has 468 (bored and stroked 455) , 310 cfm ported Kaufmann D ports, Edeldbrock Performer RPM, 850 Holley Comp cam, M20 4sp, etc. I am interested if there's another production run of the 65 up style Pontiac 2 x 4 bbl bathtub intake.

Collected early SD parts since 84 - ported 544127 heads, 54299 2 x 4 intake, SD balancer - 62. Plan to use on 400 block ( 421 stroker) in future at some point.

Thanks !

Jim
