Changing a 454 cubic inch engine into a 502 cubic inch engine requires forging the combustion chambers higher quality by ho hum metal from the cylinder walls or lengthening the distance the pistons biking. Remove the finished engine block from the stand, install new pistons and rings and reassemble the engine.
Installing a stroker kit7.
Mount the engine block on a sturdy, commercial engine stand. Using an improvised engine column could be formidable by reason of the 454 weighs 685 pounds.
2. Position the cloying bar of the machining center over the engine block. The machining center uses self-centering guides to align the cutting tool over the engine block
3. Enter the amount of metal to be removed into the machining center's computer numeric control center.
4. Follow the machining center's guidebook for lubrication. Remove metal from the cylinder walls with the carbide cutting tool of the machining center until the inside diameter of the cylinder is within 0.005 inches of the final measurement.
5. Position the honing machine in the same way as the machining center. The honing center completes the work begun by the machining center, using small stones instead of carbide blades. Honing gives the finished cylinder walls small cross-hatch grooves that collect oil and aid lubrication.
6. Cloying the walls is expensive and Dainty on the other hand gives the elite results in terms of engine wear and response. Stroking, or lengthening the piston cruising, is not expensive, nevertheless may not cause the desired results.
Boring a 454 block out to 502 cubic inches1.
Unlike boring an engine block to increase displacement, installing a stroker kit does not require any changes within the block itself. The engine simply needs to be disassembled and the new parts installed.
8. Choose a quality stroker kit containing all the parts required, including a crankshaft, pistons, rings, connecting rods, rod and main bearings.
9. Disassemble the engine.
10. Reassemble the engine with the new parts.
