>From the workshop manual:
18G, GA, GB, GF, GH, GJ, GK, 18V 584Z, 585Z, 672Z, 673Z = 160 HC (8.8) 130
LC (8.0)
18V 1972 on = 160 (LC comp ratio quoted (8.0)!)
18V581F & Y, 582F & Y, 583F & Y = 170 (only figure given but HC (9.0) and LC
8.0) comp ratios given!)
18V to ECE15 = 170 to 190 (HC only (9.0))
18V779F, 780F, 846F, 847F to ECE15 = 170 (HC only)
These figues have been given and queried before, but it's what the book
says.
