Replacing my spark plugs in a 1966 Dodge W-200 with 318 poly motor and WWW-3 Strongberg 2 Barrel Carb. What plug do I need to install and what reach of plug 3/8" or 3/4". The parts guy showed me a 3/4" reach plug which I thought was incorrect because my current one's were 3/8" reach Champion J12YC. The new plug I ended up with is a Autolite 85 is it correct? Thanks for assistance.

Have the idiot look up 65 for the engine. 66 2 engines available. A 318 and LA 318. i Ran into that problem when I installed the new A Series 318 Poly in my 66. Idiot gave me plugs for the LA Engine.

Thanks for the help on the spark plugs, I did notice in that shop manual not to be confused with chop manual that there was 2 v-8's, 318-1 and 318-3 trippy.

318-1 and 318-3 are basically the same. One is built for more HP. Those are not the designations for A and LA 318's.
