Re: Spark Plug Torque (Bobchad)
I'm not sure if the torque varies from one engine type to another, but for what it's worth my '69 service manual specifies 25 ft-lb for the plugs. This is for a 427/390 engine. Hope this helps.

Consult the plug manufacturers specs, believe most with the crush washers state 1/4 turn past snug, I pretty much use that all the time.

The risk, and tendency, seems to be to overtighten. MJ
