261 with dual Carter/Weber setup.

All six of them? One's in the process of becoming a 300 with a 24 valve twin overhead cam cylinder head.
LOL!

Yes, Jerry- all six!

I've been scavenging up stovebolt sixes for several years. I have several of them in various stages of construction, but none are quite ready for a photo shoot. The 216's are going to be 258s, the 235s go to 270, and the 261s can be a few cubic inches +/- 300, depending on bore size. All of them will have 235 full pressure crankshafts, stroked to 4 5/16 inches. The 24 valve head will be a highly modified item from an Atlas 4.2L inline six. I'm also working on a "216" with roller valve lifters and roller rocker arms.

Very cool....looking forward to seeing that Atlas head!

What purpose does the horseshoe shaped item serve?

When you install a dual carb manifold, the fender stay/support rod on that side of the truck is no longer useable because the rod would now go right through the rear carb. A lot of people just remove the rod and drive the truck without it.

A better solution is to modify the rod with a horseshoe to either go up and over or around the side of the rear carb, so that the left fender rod can still do its job.

I used an old disc brake- I plasma cut the center and one edge out of it, welded it onto the fender rod, then cut the fender rod between the welds that I made, and had a pretty sturdy modified rod after that.

Love the Detroit diesel green!

Alpine Green

darn, I’m a shade off….! Those colors look so close. I think I remember trying to find Apline in a rattle can, and Detroit diesel green was the closest I could find. Thanks for reminding me that I painted it the wrong color- lol

Dual Holley 2300 350 cfm 2bbls on Clifford intake, Clifford long tube headers, venolia forged pop up pistons, 302 GMC rods, cut down 302 bearings, Schneider 284 mechanical cam and springs, smith brothers push rods and adjusters, Manley one piece street flow exhaust valves, 50-52 powerglide intake valves, slightly enlarged and blended valve bowls, three angle valve job, vertex magneto.

Pretty fun to drive.

I'd like to hear that one run....nice build!

We made a Tech Tip out of rebuilding mine -- John's 261

BTW -- Using the 216 valve cover was a mistake. It looks cool, but it has made quite a mess of the engine. I am in the process of returning to the 261 valve cover.

John, I've got a project in mind that might solve the "leaky 216 valve cover" problem, but it's down the "things to do list" several places. It involves making a fairly simple adapter that should solve the leakage problem, but it involves some machining. Channeling Gomer Pyle- - - -"SURPRISE- - - -SURPRISE!"
LOL!

Thanks Jerry. I think I'd rather be surprised with a certain Zenith carburetor ...

That’s a nice write up on your 261 build.

Thanks Dave -- It was very much a group effort. And, of course, we couldn't have done it without Coach Jerry!

And man oh man, is THAT a sweet running engine!

Really, really, really like those Offenhauser rocker covers. Can they be snugged down tighter than the stock 216 cover? Would assume they're more flat and true as well? Currently enjoying the non-leaking 4 bolt cover on my 235 but those Offenhausers sure look great.

I bought my offy in 81 or 82, I forget now. You can’t gorilla them or you run the risk of damaging the casting. That being said, if the gasket is installed correctly, and the cover oriented to the gasket correctly, moderate tightening is really all that is necessary with the offy.

Update on engine color on my 261.
