B-3-B truck engine timing

[Ed McDermott]

Hi

I have a engine casting number #T306*I7I384* (I = cap  i)  with a date code in the head casting of  6-22-53 ,   which I believe is a truck engine model 306 and produced in June 22 1953.  I am not sure what the *I7I384 indicates.  The engine is installed in my 1948 Dodge Custom Sedan with Fluid Drive which I bought from an farm estate in Lake, Odessa MI. in 2020.  So I have no history on the vehicle.

I have the Dodge Custom manual and the timing spec's but on line data for a B-3-B 306 is different from the sedans 218 engine specs.  

Does anyone have the correct timing and sparkplug gap spec's if T306 is the id for the Truck engine model 306?

Thanks

I’ve always ran .035 on the plugs and .018-.020 on the points in my flatheads from 218 to 236. I use a vacuum gauge to help find the “sweet spot” on the timing…. Works for me ?

 

The 218 In My b3b is a Plymouth engine 

 

good luck,
