Interesting, and that's a pretty good match as you have it mocked up. That's wild to see it cut up like that.



Off topic; I asked a machine shop to use a band saw to cut four stock steel valve covers, to weld together making one taller pair. They did the work without the large band saw, and used a acetylene torch to weld them back. They didn't match, it would leak for sure, and I didn't pay them the $325 they asked for. I let them keep them needless to say. That was in about 1993 for a stock 351W that I wanted taller covers on for roller rockers. I bought some used Edelbrock covers that barely fit under the wiper motor.

I've got some of the port walls cut out of this. Can get some pics later on when I get finished cutting them out, so you can see how ugly it is. 
One thing I was wondering, the inside of the plenum where the air has to make the turn from the crossover into the ports. Should I leave the cast finish on this or polish it?

I suggest polishing the radius and the first 1" before the turns.
My own preference with no data behind it.

Ugly?  Easy now -- that's my baby and it's got lots of unique character!  When I drop that built 445" stroker in it you won't have any time to "pull over to let me pass" because I'll have already blown past you when you figure out what the hell was that loud noise behind you . . .

I'd read something the other day that pretty much mirrors what you're saying. Where you need air to turn have the surfaces smooth, where it's going straight a burr finish is preferred. Where I read that I don't remember.....

Dave or anybody, I'm asking because I don't know, Is the finish as critical on an efi intake as it is a carbed intake since its just carrying air vs the air/fuel mix of a carb?

Ambient air has "density" and due to the EFI application has more density than a carburated application.  However shearing and suspension events are a non-issue.

The exercise here is to reduce the length/time to the valve and assist the turns and hopefully not create any stalls or disruptive compression/decompression cycles in the plenum.

So far I've cut 1.35+ pounds of aluminum out of this, so I got that going for me....
It's not pretty, but it's not done yet either, even when I am done I doubt it will be pretty.

No worries, no offense taken.  

I should be able to do some back to back testing with Rod's car and mine using an unmolested TFS-R upper vs. this what is sure to be a Frankenstein looking intake once it's all welded back together.

A buddy of mine, has a very nice set up at his place, and welds for beer.

The two pieces are just setting together, so it's not lined up perfectly like it will be after welding. Once it's welded together I can use the splashzone to contour the area under the dowel, and do some final work with sanding rolls.

I put splashzone in it to smooth it out. I will probably run the sanding roll over it again and make sure the ports are uniform in size.
Hopefully the stuff stays intact while it's welded together....
Regarding the welding, is it best to weld all around the seam, or spot weld and then use epoxy to seal it off?

Rod let me experiment with what is my old TFS-R intake. I sold it to Windsordeath, who sold it to another bud, who sold it to Rod. I think that's how it went, hard to tell with those guys over in Pensacola/Jay/Walnut Hill.
The intention is to be able to compare the stock TFS-R vs. this modified stock, and the third one that I have cut most of the runner out of, and finally the TFS-R box upper.
What I intend to do with this one is to cut down that hump at the end of the crossover, and add a length of 1/2 aluminum dowel to the underside of that to help the air make the turn from the crossover to the ports.
Here's where I stopped my homeproject to cut it open, and yes a wood blade works great to cut these things, but don't try this at home.
