Not Ranked
Clois thanks for the info
A call to George A. at Gessford gave me the following advice.
Initial at 10-14 deg. and total being no more than 30-34 deg. have it all in by 2500-3000 rpm for our 428's Lots of initial lead, as much as it can handle.
Primary and secondary opening about the same.
"We changed the timing to 10 deg initial and all in by 34 deg 3300 rpm. We put in the two smallest blue springs on the dist and lost about 9 hp on the second pull. Next we switched to the two med silver springs and still lost 13 hp on the third pull. Put the med silver spring and blue spring back in the dist and made a forth pull and my hp came back to 363 hp at 5800 rpm. "
So obviously going to the slower advance curves starting working against you....first 9 hp then 13 hp....going to the blue and light silver is one step away from being at the quickest advance curve which is two light silvers. Wonder how that may have worked out?
You have to work with what you have and what else can a guy do in the setup while powertuning??
