1970 351 2v spark plugs

My 70 xr7 seems to be missing. Any recommendations for plugs and wires. Gap? Thanks Dave

Do you have the 351W or a 351C? They use different plugs.

It’s the C. Everything is new but of course that doesn’t mean it’s good parts

Depends on what type ignition you have. Is it stock or something special?

Everything is stock. It gets a little worse with the missing as the engine warms up. Initially thought it was a carburetor but replaced with no change. Timing is also what it calls for.

Hello,

Any recommendations? I appreciate the help.

I would go with Autolite 25 resistor plug.

Agreed - with stock ignition you don’t have the power needed to fire copper / platinum / special material plugs. You need the old fashioned kind.
