[DML] Re: factoid





According to Volvo:
- B27E 1975-1978, B27F 1976-1979: 5.144mm max lift cylinders 1-3,
5.059mm max lift cylinders 4-6.
- B27E 1979-1980, B28F 1980: 6.004mm max lift both sides.
- B28E 1981-1983, B28F 1981-1983: 5.96mm max lift both sides.

Valves are same diameter, length, and grind both Series all years. At
some point the intake seats were changed to "venturi seat" (multiple
angles towards the stem, I guess to improve air flow).

Valve springs:
- B27E 1975-1978, B27F 1976-1979: 47.2-32.2mm compression length
(0-131 lbs)
- B27E 1979-1980, B28E 1981-1983, B28F 1980-1983: 47.1-30.0
compression length (0-154 lbs)

Swedish and Australian B27 used same valve train as B27F, but with
high compression pistons.

Martin Gutkowski may be able to help you with Renault specs.

Peugeot, anyone?
