First step, disassembly.
Cylinders bored just below .030" over the standard 4" bore.
Cylinders are honed to finish size, 4.030", and receive a crosshatch finish for more efficiency in maintaining a fine oil coating on the cylinder walls.
Main caps are cut and then line bored back to original dimensions, checked frequently by dial bore gauge.
Balancing the crankshaft
Resurfacing cylinder heads
3 angle valve seat grind
Valves are reground to match the valve seat grind
Heads are reassembled after lapping the valves, careful attention is given to assure proper valve spring installed height, which is corrected by shims under the spring.
Pistons, crankshaft, and cam installed
Valvetrain installed
External accessories now ready to start installing

Ford 302 Engine Rebuild

In this project, I took a Ford 302 engine from a Fox Body Mustang and completely rebuilt it. All machining was done at Pierce Community College's automotive department. Machining included boring the cylinders .030 over, line boring the main journals, crosshatch honing the cylinders, resurfacing the heads, regrinding the valve seats and the valves themselves, and removing material from the pistons and crankshaft to balance the drivetrain. The final engine features the stock crankshaft, connecting rods, and heads, however all other internals as well as hardware were replaced with higher performance parts. This particular build was fairly mild as it was intended to be a daily driver and features a fairly mild cam, a rebuilt 600cfm Holley carburetor, and stock size valves. Though a relatively straightforward project, finding the correct size pushrods that would work with my valve train and new cam was quite a challenge. In the end the engine started right up and has ran without a hitch.
