In the Mar. '10 issue, we test-fitted a Ford 347 stroker kit from Summit Racing in a 302 Windsor block we had pulled from a wrecked '73 Ranchero ("Garage Built Stroker").

At first, this wasn't going to be a stroker engine buildup, but rather a 306 buildup (a 302 with a .030-inch oversize bore.) But once we saw how affordable Summit Racing Equipment's 347 kit was ...

We asked around about the difference between a Ford 347 and the 331 stroker kit for the 302.

Impressed as we were with the results of the Track Heat engine kit on the 302, the output of the modified 5.0L was nowhere near what the Street-Ports head would support.
