There are 2 that I can recall for sure, the 2.15:1 for the 4cylinders, and the 1.61:1 for the V8 engines. I am almost positive there is another, but can't remember what it is.

Barry2002,<br />Follow this link and scroll down the page till you find your model AQ's<br /> Old Volvo specs <br />The 6 cyl AQ170's had I think a ratio of about 1.91:1.<br />Even if the ratio is wrong it's not too difficult to have it changed to suit.<br />Good luck.<br />Peter

270's had a choice of: 1.61:1, 1.89:1 and 2.15:1<br /><br />A lot of gears are interchangable with diff. models. An old 270 has probably had 1 or 2 rebuilds in its life - might have to pull it down to identify the gear ratios. <br /><br />Aldo
