Will this work on a 351w. Distributors are different from 302 sbf to a 351w.

Pertornix lists all 1957-74 Year, 8 Cyl, All Models with Motorcraft Distributors. They do not list a different model for 289, 302, or 351W, that we can find, only one. We expect it to work, as long as you have a stock Motorcraft Distributor.
