I just checked the cam timing on my 1500. From what scarce info I've found online it's suppose to be 18:58, 58:18. Of course I don't know what those numbers are referenced to so it does me no good.
I've measured at the lifter 12:19, 54:29 @ 0.050. The intake centerline measures where the calculations put it but the exhaust centerline is off about 20 degrees (I could have made an error measuring with it being 3:30AM).
Is the exhause lobe assymetrical on these engines to compensate for the crappy exhause port?
If I base the centerlines off the calculations then my cam is advanced 4 degrees, which might be better with these numbers on the low-rpm torquey 1500.
The wear on the cam seems negligible and I'm getting 0.243 lift off the intake lobe. I haven't checked the exhause lobe yet. Next day off though.
Does anyone know the cam timings @ 0.050 on the lifter?
