so i've been doing alot of searching before posting this and couldn't find what i was after, so i'm thinking of buying some light weight cam gears for "ye ole starlet" (not this is a timing chain engine not pulleys so don't think serpentine pulleys) i was wondering if there is a decent FE gain from it (as rotating mass reduction has a greater effect than normal weight reduction). when i say decent i mean 1km extra to the litre or about 3.8 mpg extra, will keep searching but would be good tohere your thoughts or tests already done
