Is your Mallory Dual Point an old unit? If so, you may want to get rid of it. You can update to a transistorized ignition if you so choose. MSD makes a "ready to run" distributor for the 302 ford that works great. All you have to do is install it, time the engine and never look at it again unless you pull the unit. I have a friend who bought one for his 302 in his 34 ford. Works great for him. Cost is moderate, about $300.00 but you will not have to change coils (it uses the stock coil) and you'll never have to set points again.
