I'd say a boat.

its the first  Chrysler   383 motor I believe  in    1958 or 59   ,   its a RB  block   ( raised block)    think this is the  type of 383 that had a long ram set up , although cant be sure

If you can, remove T.C.  Maybe a M- marine
                                             R- reverse rotation, using a gear drive
Just a thought.

The location of the data pad makes it an RB. If it is a 383 it is '59 and '60 only; casting number would be 2120329 and original bore of 4.062".

Looks correct from what I have found. This is what I think it is;
MR383 - MR38=1959 383 (RB Block), 3=Evansville Plant
11370 is the production number. Since they started at 1001 that would make it number 10369 produced.
So it was the 10369th 383 RB Block produced at the Evanville Plant in 1959. And in 1959 it would have come with the ram intake as tan top stated.
