Stop in for a cup of coffee

Two light springs whacks the advance all the way in right away. around 1500 rpm or so depending on the spring tension. Great for a drag car not a cruiser.

That's what worked well with my 68 Barracuda... the stock MP electronic light spring with one of the MP light advance springs...

But his engine may not like that as my cam was a larger.... But I thought that would be a good starting point...
