Timing tuning??

[slownova73]

having trouble adjusting the timing in my 383, its popping out of the exhaust when i give it a little gas, and puffing white smoke out too. the disributor is in the correct spot, all the wires are correct, sparks plugs are good, and i have an inductive style timing light. help me out please.

If you pulled the distributor, are you sure that you don't have the distributor 180 degrees off?

On a Chevy, counterclockwise advances the timing; clockwise retards it.

Can't help you there. I run a HEI on my car and don't have any experience with MSD boxes.

Unfortunately the dial back/digital timing lights cannot read the signal under 3000 RPM because you are getting 2-3 sparks for each cylinder.
The problem at higher rpm's is that it is still 1 spark, but it's a longer duration spark.

The dial back timing lights usually will not give you an accurate timing readout regardless of RPM.
MSD recommends a basic, no thrills or frills,inductive pick up timing light and your timing issues will be just fine.


Good Luck!
