Aftermarket module and coil on HEI

[TDR]

Is it worth the money on them and what kind of gains is there having them?

[TDR]

No opinions on whether a msd or DUI coil and module are better than stock?

our track champ in the crate late division run a standard hei setup that came from GM. our local mod runner up does the same thing. he just has a standard HEI setup from GM. (only reason i know both did this is because i know the guy that bought the lm champs engine complete, and the mod guy built all our limited motors for a long time)
