36.13 cubes to be exact for the 40 horse twins.

The 48 horse models shared a block with the 60 twins at 46.37 cubic inches.

The twin 48 ending in 1979 then the 60 stopped production in 1983.

In 1985 they started building the twin 55 using the same 46.37 cu in block, but scrapped it (and the larger twin block) after the 86 model year."

Plus just finished up a total kitchen remodel which has kept me occupied for the last month.

I should have stayed working - been 3x as busy as ever since I retired
