I got a B20 for my 122s Coupe swap/upgrade, but which B20 did I get? 120-130

"I have the 1972 manual. It would be nice if we had his motortype number to verify."

But do we need it? If the 1972 manual shows all B20B engines (US Spec included) at 118 hp, it follows that my brochure is correct... the very last of the B's imported to the US (1972 model year) were still 9.3 to 1 compression. This despite the fact that the 1972 D-jet engines were detuned - using the newer (B20F) head and lower compression ratio.

Besides... as I've pointed out before, the motortype number identifies the engine configuration as it left the factory, nothing more. By now (nearly 35-40 years later) engine blocks and heads have been mixed and matched to an unknown extent.
