Bathtub Tunnel Ram intake pics
I just thought I'd share some pics of the Pontiac bathtub repro intake I was lucky enough to get my hands on.
I figured I'd post them here in the Pontiac - Street forum since this intake will end up on a street car.  Needless to say I'm pretty stoked.

Any chance these will be repro'd again? I'd love to put one on my '65 GTO.

As it sits, curious, what's the over height to the carb flange?

At the very front it's 6-1/8", at the back 7-1/4". I measured from the very bottom of the intake itself to the top of the carb mounting flanges. |

I've seen first hand what a clay radius does to an intake port on the flow bench.
I can't believe there's no radius at all on this manifold. |

Adding a radius to the port entrances in the plenum is no big deal, and that's probably all I'll ever do to it. This is a very nice piece, rounding off a few sharp edges is about all that was left out in the casting process.

A few mockup pics. No carbs, linkage or fuel lines yet.
I'll probably end up running it on some E-heads.     Checking carb pad height in relation to the valve cover rail.    Comparing to my RPM intake, the two gaskets sitting on the carb pad make up for the .180" that I had millled off of it.  A little bit of weld added to both front head corners will allow the '61 -'64 water crossover design to seal up. I'll have to plug and move some bolt holes slightly that seal the intake runners. Will also need to plug off and reshape the water passages at the front of the heads and drill and tap 2 new holes for the front crossover bolts. I'll modify the E-heads heads to fit the intake, rather than the other way around. Or I may end up running on some early SD heads, still trying to decide.    You can see straight down to the intake ports in the heads from the intake plenum, some port matching will be needed of course. Ports at the manifold flange are pretty wide, averaging close to 1.200".

Moving along now, I managed to dig up a nice matching pair of 1966 389 auto-trans 4034S AFB (575 cfm) automatic carbs. I was able to find them right here on PY by posting a 'parts wanted' ad.
Now I can build up the linkage and fuel lines.

I'm pretty hard-core when it comes to cars and Pontiacs especially. Hard-core just like you with your passion for your rides and playin' rock 'n roll. Myself I am in awe of musicians and singers like yourself who get up on the stage and lay it all on the line. Say hi to Storm and the Balls for me.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
