thunder bolt modules
 

I am reloacting them on the engine. I knew that the 2nd module was a spare. As I inspected them further I discovered that they are different. One module is P#4E26A V8-HP (not used) and the other one I was currently using P#6A05A V6-14.
What gives....? I wonder if it is some timing issue (retard while starting or high rpm retard?? This seems odd to me.

2nd module Is that a spare and no wires are hooked to it?

The V6 14 is 14 total degrees advance. Used alot in blower applications.

There is a V-6 module new on e-bay for $20.00

The V-6 module will give you a 14* advance when used on a V-6 engine. When used on a V-8 it will give you much less. (8 to 10 degrees); and yes, they are popular on blower blower motors and others running a lower basic compression ratio that allows starting at an initial high timing setting. The V-8 HP is probably a better choice for a naturally aspirated "spiced-up" V-8 with a compression ratio of anything over 9.5:1 or so. --- Jer

Would you consider selling the V6 module. I am in need of one.
