sleek lemur - HS6 - 1-3/4"
On a completely different subject next season due to a cam change and cylinder head improvements we are going to use this set of Volvo Competition Service Solex 45 ADDHE carbs and manifolds. Last edited by Vintagewrench; Oct 23rd, 2020 at 12:56. |

http://www.1800philes.com/ianr/_superlist_grinds.html suggests that the primary difference is in the initial opening and overlap. The timing of the 0.050" lift suggests that the cams are pretty much the same after that. I believe that the initial exhaust emission limits in the US were all about checking compliance around idle speed. The marginal reduction in overlap on the K cam probably helped to bring the B20F into compliance at low engine loads. Since Euro and GB emission regulations lagged the US I know that the B20E was available on the east side of the Atlantic after 1971. Did the K cam come into use on the post 1971 B20 cars with D jet and K jet or did they continue with the D cam? |

Yes I'm aware of that cam list and should have looked at it before posting. I've also read that it hasn't been updated for a long time and that there's some anomalies in there. I can't think that Volvo would have kept the D cam for the K-jet in Europe, especially for the small number of units needed. There were also some C.R. changes, down, I've not looked at those either but they probably suited the K more than the D.

Thanks all for really interesting replies.
Vintagewrench, sorry about getting your name wrong. I have a friend with a business called Vintage Watch! I'm waiting for information from Brookhouse and will be sure to pass it on. |
