According to a August 1977 AC 706B operators manual the following 2 engines were available;

Ford gasoline 192 cu in 4 cylinder 3.1L 56hp, 7:1 compression ratio

Perkins diesel 4.203 203 cu in 3.3L 4 cylinder 50hp, 17.4:1 compression ratio

Both engines spec, 2400-2550diesel 2500-2650gas rpm rated speeds, 12V electrics, negative ground, 8 quarts of oil, 16qts coolant. 706b has 20 gal fuel tank & 30 gal hydraulic system.

Now, if you have an AC 706b like mine it has been retrofitted with another engine? Mine has a continental 4 cylinder f227 gas engine. It is under powered by my standards. I hope to swap an AC 433T or AC 226 d17 gas into it soon.

Thanks for all the help. As far as i know it has the original gas engine in it. By any chance do you know what ford engine was put in it or just that it was 192cu in 3.1L

Thanks , Doyle
