Jack,
Went out and looked at some manifolds. 3835590 appears on three 235
manifolds. These are the tall carb mount variety. Also have two, one off a 235
and one off a 261 with a 3754644. These are the low carb mount variety. Can't
swear the '63 (yes, '63 4wd used a 261) 261 had it's original manifold. I didn't
know the 261 had a specific manifold. I see it's carb had a bigger venturi and
any other Rochester I've seen.
Also checked a 216 manifold, 3835527.
