The Ford Barn - View Single Post - 59A-B parts into an 8BA block

There are a few things to be aware of before building such an engine with 8BA style block and 59A components----

Although it will "probably" run for many miles, it will not have the formidable longivity of the stock Ford design. Here is why:

The 8ba block does not have front gear oiling provision of the 59A. Using the 59A cam and gears will result in more heat and wear at the gears, block face, and front cover.

The 8BA block does not have the waterpump oiling passages of the 59A so using 59A waterpumps by blocking the upper pump holes will result in earlier pump failure. There are non-Ford pumps available, with sealed bearings, which might solve this problem.
