Hello all -- I have a 71 6.3 - does anyone know ohm spec for plug wires -- highest one is 6.4 K and lowest is 5.3K -- I also need to know location of fuel pump dipstick(if there is one) and what viscosity oil to use if low. While I am at it, I took off cold start hex plugs, started vehicle, fuel initially came out in what I presumme is normal and then nothing further once vehcile started and ran -- is that normal? Thanks for the help.
