Re: Camshaft specs help
Sorry, I don't have all that much G/K BB cam info.
And I do want to say that back in their day, G/K cams were NOT generic cams, but rather very good old-school designs, imho.
They list two SB cams in particular, one, the C1H-270-S, 270/216, 110/?, .454" lift and the other, the C1H-290-S, 290/218, 114/?, .450" lift.
They illustrate wide and narrow LCA theory from back in the early '80's (and I figure earlier). I contacted them and asked what the difference is between them, and I still have a short note back from them explaining that it would take a whole lot longer note to expain the theory behind why they look the same, but will operate so differently.
PS., I got my G/K info from the now, long gone Hollywood Sams Auto Parts, Inc., in Detriot, MI.... I first bought the 290 cam and ended up taking it back and getting the 270 one later.. It's in my Nephew's 327 motor that I gave him..
