Outlet is angled back, seems to be the same as others I have except that it won't bolt to the intakes I have. This one has inner bolts that attach it to the intake spaced 2.50" apart, all the others I have are about 2.12" spacing. Cast # is 8836388.

The 216 manifold intake alignment sleeve measures 1 13/32" OD by 3/8" HIGH, 235 sleeve is 1 17/32". So find either intake to determine what you've got for an exhaust. | | | | | Joined: Sep 2011 Posts: 1,456 'Bolter | | 'Bolter Joined: Sep 2011 Posts: 1,456 | Have 3 intake off 235 / 261, none mate to it. Exhaust ports all line up w/ other 235 / 261 exhaust manifolds I have. This odd one also has the firing order cast into the front runner which the others don't.

Starting in 1949, with the redesigned steering design for the passenger car, Chevrolet angled the dump at an angle backwards.
Just so they only had to make one design, they used this same angled manifold on trucks until 1953.

It's been split for dual outlet w/ functioning heat valve. Bought it a few years back. supposed to fit 235. Oh well, at least I know what I have.

Just for future searches, the bolt spacing is the same on all 216’s and 1941-49 truck 235’s, which use the same manifold as the 216.

Once again, thanks for all the help!
