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

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. Jerry

What purpose does the horseshoe shaped item serve?
"Do not walk behind me, for I may not lead. Do not walk ahead of me, for I may not follow. Do not walk beside me either. Just leave me alone, you're starting to freak me out."
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.

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

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! Jerry

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.
