Piston - Big-bore Modifications and more,...

The hot-rodders time honored #1 technique is bigger pistons. Stroker crankshafts is second,...but regardless,..bigger is always better. Modern boring and plateau honing is an exacting machining and finishing process, requiring patience and experience. Proper clearancing and finish detail is absolutely critical to any high performance motor's power and longevity. The latest methods can exceed original equipment specifications and promote increased durability and strength. Replacing sleeves, along with boring and 'Nikasil' re- plating, can allow greater engine displacements than more common aftermarket kits.
