Small top I think. Haven't looked at it in a while but I'd say it is smaller in volume than the one in this thread before he cut it.
Edit...
I may have misspoke. Could be a TR5. I think this is a pic of it before I picked it up but its stashed in the attic at the moment.

Small top is 173 cubic inches. Perfect for a 340. That’s the try1 top same as a Chevy
How's the traction/tire/suspension situation? I ask because some folks who have filled the bottom of a traditional "V" TR Plenum to near the runner bottoms, found out they had a problem hooking all of a sudden, lol....
There was no need to use a saw blade. The aluminum is only 3/16" of an inch thick on the sides of the plenum. The cutoff disc only removes .062" and in my opinion a whole lot safer than a toothed blade for my application. It cut super clean, took no time to do it, plus it was a very easy and economical way to do it. Had I felt I needed a toothed blade I would have used one. However aluminum that thin doesn't require over thinking the process.

That's a great read !
65 cubic inches?
I've been really busy the last 5-weeks, but managed to get back on the plenum project a few days ago. Got the edges all beveled and the halves welded back together. Started filing the welds smooth and a little 50-grit sandpaper works wonders on aluminum. Once the filing and sanding is all done I'll make 4 block off plates to cover the machined surfaces and glass bead it all over. When finished I doubt anyone will ever be able to tell it was very shortened. Lots of work, but a really enjoyable project.

I can't remember but did you say how much you took out, volume wise?

I have about 3 hours worth of filing and sanding to be half way finished with blending the weld in at this point.
Now that one side and one end is totally finished I am really happy with the progress so far. I'll do a little more sanding before I glass bead it and no one will ever know.

Tom, FWIW, would you do a little detailing of the work you’re currently doing? A short how to in the outside of the manifold?
There's really not much to it. You just need an assortment of files (two rounds, a flat, and a triangle), some 50 & 80 grit sandpaper, and a glove to wear when sanding, so you don't
wear your thumb out (It hurts). The blue handle file is a really coarse and cuts with ease. I find that I've used the edge of it for tight work a lot. You just file in whatever
direction/ angle that works.
Several of my friend have asked why I haven't used power or pneumatic tools and I told them I wanted more control. It's just to easy to make mistakes with fast cutting tools.
If you take one file stroke at a time you can control the removal process and direction much easier.
It's not hard, it just requires time, effort, and attention to detail.

Just about finished with only 4-3/4" on the end left to do out of the 41" all the way around, but I need to give my sore thumb a rest for at least a day before I can work on it again.
Fortunately the end is a lot easier to do, so it will go quickly.

Good job on a cool project
That one vs an unmodified one on the dyno would be a fun test.

It's going to do some back to back testing when the time comes. I am also getting ready to cut another top right under the carb pads and weld a plate on that will
accommodate an Enderle Birdcatcher.

The filing of the weld has finally been completed. I might have to do a small touch up here or there, and still have some sanding to do before it's ready for glass beading.
Went ahead and removed the Mopar logo and the part number (something I always strip off of every intake I use) and smoothed that up a bit. Probably make the 4 plywood plates to
cover the machined surfaces in the next few day (when my thumb feels better) and try to get it blasted by the middle of next week.

Tom that looks incredible. You do some great work!
Block off plates made and installed today covering the machined surfaces. There is no point in filling the inside with trash and dust.
Hoping to get it bead blasted tomorrow and call it done.

Got the plenum bead blasted today and tomorrow I should have the powder coating done. Need to get this one finished, so I can start another one for the Birdcatcher project.
