A very nice car. Did it originally come with a 383?
Dana 53 ?????
I just looked at the engine section of my 66 FSM and there are no reference to, or service procedures on the 440 engine listed.
I wonder if it was a later production option.
Wil: I too am wondering if the 440 was ever available in a Plymouth in '66. I never saw one or heard of one, back in the day - a hemi in a B-Body, yeah, but not a 440. If it was available, it had to be a late change engine-option.
