I have searched on here with conflicting answers.
Bringing a 1978 Chrysler 120 HP back to life. Free motor, great compressions, and a RAPAIR-ed upgraded CDI box with good coil. Getting good spark. I will get a strength reading on it today.
The plugs in this motor are "surface fire" type plugs (the electrode is in the center, and does not stick out, the end of the plugs are basically flat), which I have now read (never heard of them before now) are used often in tight racing motors, and they can run at any temp, but do not really get enough spark far enough into the chamber (because they are flat). What are the spec plugs I should be using? Do I have clearance for normal plugs with the electrode coming of the side of the end?
I do have a manual coming, but probably will be a week before I get it.
Also, the firing order. I thought it was 1-2-3-4, then on this site, I have read both 1-2-3-4 AND 1-3-2-4.
ANY ANSWERS WOULD BE GREATLY APPRECIATED. Thanks.
This motor is going on a tri-hull that is ready to go otherwise.
