I was curious to see what engines were available that year and saw that the NASCAR 427 Ford Side Oilers were available in either single (Q code) or double Carbs (R code). While I was looking at the list of available engines, I spotted some engines shown as both low compression like this: 8-260 low compression and the other as simply 8-260. Different vin codes as well. So, is there one among us who actually knows what the difference is? Besides the 260 cid, all of the other listed engines had low comp engines listed also. And why, I wonder. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Just curious.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>larry<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'>_________________________<br>drmayf<br>Worlds Fastest Sunbeam, period.<br>204.913 mph flying mile<br>210.779 mph top speed<o:p></o:p></span></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
