I'd like to get more initial timing in the 340 in the Dart...I'm currently running MSD with the black 18 degree bushing... Does anyone have experience with these bushings? One is 10 degree and the other is 14 degree... http://4secondsflat.com/MSD%20Distributor%20Tuning.htm
I have those bushing $10 ea + shipping
CNC'd and the 10 is flat sided already as well to help fit in the window.
Sold quite a few to members here and and FABO, FBBO.
