My Brother had a 69 Mach 1. The styling had changed just a little but it was a nice looking car. It had a 351 with a four barrel. I don’t remember the HP but it was not as hot as I thought it should have been but not slow either.
It did sound real good.
Conservatively rated at 290hp at 5800 rpm IIRC.Thats going back some years now.
