Do you know what the engine number is? The engine number will be helpful in identifying what donor car  the 186 cubic inch engine came out of. Also whether it is a low compression or high compression motor. A suitable carburettor can then be matched to the engine.
For my 202 cubic inch engine I fitted a re-manufactured carburettor  23-3091 BXUV-3 2375152 Holden HJ and LH and LX Torana 202ci six cylinder engines with manual transmissions (1975-1976).
Have fun with the blue beast Cookie. Let me know when you track down the number for the carburettor that is currently on your engine.
Kind Regards
Lionel
