Since you have highports, maybe the Hogan "bathtub" replica intake would be for you? here a pic of the one Larry Quinn had them make.

Thats not a Hogan bathtub. That is one of the castings Dave Johnson and I did. Larry had it modified. Larry had Hogan build a bathtub type intake to replace the manafold in the picture in the above post.

I've got the Hogan on my car now Marty.

S/S Racer John Schloa called me today looking for one of these intakes. Told him to get a hold on Tom S.

Agree, Dave Johnson (may his soul rest in eternal peace) and Joe Z. were the main guys in getting the intake in the picture above sorted out. Their intake was a lot better vs the Flat Floor intake for the type of racing that they were doing.

Are the molds still around? Why don't they just cast more of them?

[pont406]

The Molds, Manifolds, etc were part of a project by Randy Williams, Joe Zajac, and Dave Johnson to make a competitive "bathtub" intake for the class for the Pontiac guys.

Joe ran one of the Intakes on his 63 Catalina Race Car as did Dave Johnson and a few other Pontiac Racers (like Scott Tiemann on Randy's Tempest 2-door drag wagon.

When Randy died, all of his rare Pontiac parts, the molds, etc went to his wife. She wants a lump sum for all of it. So the molds are not available to make more intakes like the old ones. Yes they are around, but not available unless you have 1,000,000 to buy the whole package of parts.

Yeah that's what Tom S told me, but I thought he had molds for the flat floor intake, not the V floor (I assumed there were two sets). Too bad, I doubt that stuff will ever sell for that price.

[Tom Vaught]

There were some early Dave Johnson, Rick Johnson, Joe Zajac, "flat floor" Bathtub intakes made (before my time helping them) that may not have been part of the Randy Williams project. More of a recast of the original Bathtub intake. That stuff might still be out there somewhere else. No "V" plenum stuff.

Tom, Any updates on this project?

[tom s]

As of this time not enough interest.I think we would have to sell at least 50 to make it work.I have a guy that can make the 3D molds but then they would have to be cast and machined.Tom

We all appreciate the effort, Tom. Out of curiosity, what would the price be if you met your 50 manifolds? I'd probably have 5K in it by the time Jim got it to finally fit my heads

[tom s]

I have put the project in another persons hands.I will offer up my intake to be digitized if and when the time comes.Tom

[HotCat_63]

Gee, that V-Plentum bathtub sure looks familiar!

[tom s]

FYI,I had 3 diff versions of Randys bathtub intakes test side by side on a engine dyno.There was a flat floor,a V with round entry going into port shape and V plenum with port shape in the V.This was on a E headed 460ish engine.They all were within 5 HP at peak of each other.The intakes and dyno sheets were returned to Randy.FWIW,Tom

So, one can presume that the floor design and runner entry shape had no effect on HP? That's kinda surprising.

[tom s]

Craig,I believe it was because of the engine design.That was a 6500 RPM engine.I think when a engine get in the 8K range which is what Dave,Rick and Joe started running the shorter(V plenum)came into its own.I think the factory design with runner length was right on for the SD project.I had a engine on Joe Shermans dyno a year or so ago with a single 4 SD intake and carb and asked Joe to put my bathtub with a pair of SD AFBs on it and he said would be a complete waist of time because it was a 6K RPM engine.Pickup 35 HP with NO tuning.He still talks about it.Tom

[Craig Hendrickson]

Tom,

OK, that makes sense, now.

Same deal on the TR Kern & I built for the 326. We ran the TR one weekend at Big Willie's drag strip on Terminal Island on a more or less stock 455HO with a HC-03 hydraulic cam in my (at the time NHRA record holding 1974 T/A) and it went (relatively) nice and slow (12s something instead of low 11s).

Unfortunately, Big Willie allowed informal cash money betting on each race since that is what happened at their illegal races at 2AM in City of Industry and such places, so a lot of Pontiac/H-O Racing fans lost some $$$ on that exhibition match off (can't remember the opponent). After that race, one of my pit crew advised that I "shouldn't do that again." I didn't.
