Looking at buying a new distributor for the 440 in the Newport. Currently running the MP electronic and having some issues with too much advance under vacuum. I know that's adjustable but after reading up on these it sounds like they have issues with jumpy timing and such. So, what are the differences between the Firecore and the FBO billet distributors? Besides 100 bucks that is if I don't have Don tailor make a curve for a new one...... Will the Mallory adjuster kits work in either of these dizzys?
