Thoughts on swapping a slant 6 with a 383

No, that is NOT correct. There was no slant six center link after 1965.
Jim, back topic seraches show that you seem to really be stuck on this argument for some bizzare reason..triggered much?
there are in fact two different links.
To run headers, one needs the deeper drop center link, more commonly called: the V8 link, by, well nearly everyone (perhaps tis just a wee bit of semantics) the shallow one will not work "most of the time" and can also hit some oil pans or land very close to doing so.
Plenty of info out there about this very topic and as always varying opinions..to which again you choose to argue repeatedly about. ffs.
A lot also seems to depend on the car being worked on, the engine, the motor mounts used, the year of parts, etc.
OP, Ive ( & many, many, many others) always gone ahead and purchased the "v8" link when converting a /6 over to B/RB drive train and never had any issues from doing so...call it a safe bet. kinda like fresh oil, new gaskets, etc..even if they are "not needed" to make the engine run....
