Although I heard all over the place ,YOU CAN'T CAM A SPEED DENSITY MUSTANG ,i'm happy to report the car idles smoothly at 850 prm's with no up and down idle .The cam sound a lot like the E 303 cam.

Fellow you got me wrong on this one.I'm just excited I didn't have convert to mass air.I did reset the timing advancing to 10 degrees seemed to help a lot but still falls a little in second.How do you check ,adjust fuel pressure ?Also what about 24 lb injectors or do I need them?Any help would be appricated.

Phildeez69 thanks for asking I adjusted the timing last night to 10 degrees advance and it seemed to do a lot better but i've since found out I needed to have disconnected the spout that is connected to the spout that plugs into the distributor.My bad but i'm hoping to get that problem fixed tonight.
