Hello George,

The MR code was used for the 400 CI in the 1966 GS

325 HP and 10.25:1 compression ratio

I'm not sure about that Carter carb, but I'll keep searching.

 

Sorry correction on the block code,its MT i`m sorry,yea ok Jim.

Thanks

:grin:

 

MT = 1966 modelyear 401 CI, 325 HP and 10.25:1 comp ratio

Used for the Wildcat, Electra and Riviera.

 

Thanks,if you get any info on the carb#`s let me know.

Thanks:TU:

 

It's from a 401 1966 automatic. I have a 1966 GS 401 Auto, but don't have the stock carb, it was replaced by an New 750 Edelbrock for the guy I purchased the car from. Unfortunately the Edelbrock is not properly set up /jetted,/tuned for my application.
