No splash shield. The exhaust crossover has been milled off and a plate welded on it’s place.
“New” Intake

Maybe make a round plate the diameter of the wood buck and weld a steel bar or pipe to it. Then drill several holes in it and screw it to the end of the wood. .125 3003 will be real stuff to shape on that form without annealing, since it's so small and tight bends. I've used some good hose clamps to help pull thinner aluminum onto a little larger but similar shaped form. I think you might be surprised just how much easier the aluminum will bend after annealing. When I started working with .125 aluminum, I could not bend it by hand before annealing. After annealing it was pretty easy to bend by hand.
This is great and I get it Dan, but it was done 25 years ago. Please explain?
5052-SO is soft for forming and can be welded in its original state. It's used mostly for engine cowlings, fairings, wigtips and anything needing hand forming or stamping on aircraft.

Thanks Cecil, good info and I’m thinking about building a sheet metal intake. Sounds like it would be perfect for that project. Easily bendable but it is not heat treatable, and I don’t plan on heat treating it anyway. Thanks again.
This is some scrap 6061 need a lot more practice!
Some days it goes so smooth and other days I’m all over the place!

Kinda biting my lip on this one and not really sure how to respond. My first reaction was probably the wrong one. So I’ll ask what someone doing something like this 25 years ago has to do with anything?

This is just an outstanding project! Chevy had a fascination for dual plane intakes and it didn't serve them well at all. The 409 port entry angles were too low at best, the half of the engine that was fed through the lower half of the intake had really bad port entry angles. Cylinders # 1,2,7&8 were so different than the other four that the horsepower differences cylinder to cylinder must have been immense. Sheet metal tall intakes, not even of the tunnel ram type with equal length and angles can't help but help things a lot. #6 intake runner on a small port iron 340 horse 409 intake is about the bottom of the heap when it comes to airflow and volumetric efficiency.
You don't know until you try it. Besides, it keeps you out of the strip bars. If it works you may be the new Edison, or even Einstein.....good luck
I didn't intend to offend you Dan. Have fun, that's the main thing.

You might try using a B/RB Mopar intake afor a donor as the runners are pretty close to the 'W' stuff. Cut the Mopar intake runner off where they meet the sides, make up a sheet valley cover and sides, weld the MoPar donor to the side plates...bada bing, bada boom. Well...not that easy but you get the idea. Did a couple of those a long time ago...worked well with both an 4781 Holley and a small Dominator. Intakes were the Edelbrock single plane.
A really slick one would be the Weiand single plane 440-6 intake with three 4412 Holleys. The plenum is pretty small so you don't have the huge signal loss and resultant fuel puddling of bigger tunnel rams. They also had single 4 tops for them. They pop up fairly often for sale. With a bit of plenum work, they made huge torque numbers on the 440 6 Pack Super Stockers in the day.
They can be hard to find for sale because no one wants to give them up as normal.You might try using a B/RB Mopar intake afor a donor as the runners are pretty close to the 'W' stuff.

I'm not talking about modifying the normal tunnel rams. The pic says it all.
That’s interesting Al, thanks. It might be possible once you cut off the mounting plates to fit a z-11 valley cover. I’m sure it would need modifying. Mcquillen makes them. Ralph had a 440 torquer modified to fit a w motor, they split the plenum and stretched it front to back and used a z-11 valley cover... thanks again I’ll be on the hunt. A sheet valley cover and sides shouldn’t be too hard to fabricate.You might try using a B/RB Mopar intake afor a donor as the runners are pretty close to the 'W' stuff.

I forgot to mention that this tunnel is 383-400 Mopar. The 440 stuff isn't very close. The 383-400 is nearly perfect match on the runners.
Looking good Dan ........ did you do a lot of research before delving into this project .........?
