Post big block with no torque II

I posted a few days ago that my big block powered 4x4 had no balls off the line or in the mud ( posted as big block with no torque 10/12/02). I got a lot of feedback and I appreciate all of it. I think I have identified some of my problem and want to ask your guys opinion.

It seems the cam I chose has a 4 degree advance ground in to it (pretty standard for most aftermarket cams), Also the cheap timing chain I got from Autozone also has a 4 degree advance figured in to the timing mark. Because I installed the cam dot to dot I now have 8 degrees of cam timing (advance). Do you think this much cam timing and a 13 degree intial timing will give me symptoms of no power off the line? Also is there any way to composate for this with distributor timing or are they like apples and oranges?

Hey thats good news!, swap out the chain set. Hopefully this will alleviate most of your problems. You can't adjust external timing to compensate using the distributor.

Changing your cam/valve timing adjusts whether your valves open up earlier or later, this is different than ignition timing (moving distributor) which just changes when your plug fires.
