Not Ranked

Might be a good suggestion on the idle increase. My 427R with a Holley 870 puts out 10-10.25 in. of vacumn at 1000 to 1050 RPMs at idle, with the idle mixture screws adjusted to the "highest vacumn" setting. If I remeber correctly 10 in. was the min. that Superformance recomends for the brake booster.
