A 351 Windsor has very similar dimensions to a 302, heads are interchangeable, but intake is not as the 351 has a 9.5 inch deck height versus the 302's 9 inch. Same mounts and bellhousing also, and of course with more cubes you get more torque and HP potential. I have had dozens of small block Fords over the years and always found them to be a good motor. In fact I had a 68 Fairlane when I was 16, with a 289 auto that was a decent runner, only real mods were headers, still had a 2 bbl carb.
