So I think I have figured out the cam I want, but I can't justify getting it without understanding some of the others... that and it seems to me that the only reason I am going with it is because they idiot proof'ed the cam via your cruising RPM's haha.
I am looking at Crane Cams' HR204/286-25-12 Which is a lift of 204 int, and 214 ex, @ .050 with a 112 Lobe Seperation and .429 lift int, and .430 lift exhaust... now I have no idea what that mumbo jumbo means, but they idiot proofed me by saying in the description "2200-3000 cruise rpm w/ 8-9.5 compression ratio"... and it says "light towing daily usage and smooth idle"... so I was like HEY THATS ME!
But than I searched like any good moron and second guessing myself constantly now, such as looking at the comp cams' magnum series 56-440-8, which is a 206 int, 210 ex @ .050" with a 112 Lob seperation and .500 lift int and exhaust. Once again I have no idea what this means, but it sure does have a pretty saying that my rpm range will be ARRROUUNNNDD 1200 - 4500 and no other real information to let me understand it.
But than I got to reading and I seen this information given.
"Factory 4.3L Cam Specs
*'96-'00, VIN W, w/ balance shaft
- Lift (I/E) - .415/.429
- Dur @ .050 (I/E) - .191/.195
*'92-'95, Vin W, w/ balance shaft
- Lift (I/E) - .432/.440
- Dur @ .050 (I/E) - .208/.208"
Like I said, I don't understand this all very well, but from the looks of it just by looking at lifts and durations, the 92-95 W cam shaft appears to be up there with the performance company camshafts.
I am looking for something I should be able to hopefully obtain easily obtain, and be able to drop in hopefully without changing anything else, unless it is obviously worn out. I do tow a few times a year, and I plow during winter, but I primarily use it as a daily driver that I have done intake and exhaust bolt-on's to. I also am hoping to not have to get a full tune or anything for it... please help me understand this before paying?!
