lugnut123, I think we are trying to say "be sure what you are getting". The seller may not know what he has, or may just be calling it a 235 by mistake. As trucknix wrote, there are no 1964 235's. If it is a 64 then it's a 230. Very different motor: Nothing from your 216 will fit on it. It will have side motor mounts and a bellhousing like a
V8 . A 230/250/292 swap can certainly be done in your 41 truck, but it's more work and different parts than a 235/261.
