my 72 440 wagon is stock as stock can be other than a street demon carb with choke. Even after sitting over the winter, it will start on the 2nd try. Even now, it hasnt been start or even looked at in 2 weeks, Pedal to the floor twice, crank her up and it will start. it will idle like crap for about 15-20 seconds and then be smooth as a 440 can be.

Plugs in the car have about 15K miles on them and are 4 years old. havent pulled one since they went in.
