G henry - we had to blast the magnesium, it's really the only way to clean it off. Then a light touch up with steel wool brings it back to pretty close to what it looks like new, or with just a little time having past since it was new.
tseaberg: Your buddy was close... in 1977 they tried a 440 twin motor, the triples were better, so by the time they hit the ice for the first race in 1977 and all the way through 1978, the 440's were all triples... as far as I know. Never saw a picture of an ifs with a twin 440 in it. Thanks for looking through the mags for me! I also have a giant stack of snow weeks that I've been putting off going through -
Could be a quaker state decal - but it doesn't look like its shaped like any Quaker state decal I've seen(??) I was told the reason they ran any of those decals (quaker state, champion, ngk, wiseco) was if they won they got an extra $100 for having them on there.
