Am I out in left field on this one?

But at 8 amps constant for the HD Meziere, it's still substantially more efficient than a stock mechanical pump, particularly so as engine speed climbs.

I know it's long, but I tried to cover everything. Our Tech Tips on our forum has a lot of good ideas and techniques.

1. Do you think it's a good idea to up-grade the Damper at this point ?
If so what one would you recommend ?
2. Is there a better opti-spark option then the OEM ?
3. What about a Cloyes Tru-Roller Timing set ?
I truly enjoyed the article you wrote-up, thanks.....
