I Just thought I'd check under the cover of a 1750 engine I'm getting ready to sell and found what appears to be non-standard cams for that model. The only mark on them is a stamped "520", as shown in the pic. I compared it with a stock 1750 cam measuring from the back of the lobe to the tip. It measured 1.420" (just over 36mm) as compared to 1.448" (just under 37mm) on the stock cam. I guess that would mean less lift than stock? I should point out that my shadetree mechanics have consisted primarily of "make it run" endevors more than "make it perform" so my knowledge of cam profiles is pretty scant (okay, non-existant). I'm mostly hoping someone will recognize this cam and tell me if it's worth the trouble of swapping out for when I get a chance to read all those past cam threads. At this point, all of my cars are for street, not track, use. Thanks.
