I had a 95 F150 with the 351W that I used to tow with. I think it was only rated at 210 HP then with EFI and was a non roller cam as well. It had 325# torque, but at 2800 rpm. It was a really good engine in that truck as far as pulling with a 1/2 ton 4x4. The Lightning trucks of the day had the GT40 heads I think, but I never drove one for comparison.
I also have the parts for a 69 290HP 351W, but feel its too high a factor to start out with in S/SS unless you really want to do it.
