- The 97 in. Big Bore kits for 88 in. motors yield excellent results with stock cylinder heads
- Feature the largest bore (3.927 in.) that can safely be used in a cylinder with stock spigot diameter
- Even though stock cylinders can be bored to fit the 3.927 in. pistons, the included S&S cylinders feature a much stronger cast iron liner to stand up to the added power
- Easy installation: no need to bore or split existing cases, just swap the cylinders
- Feature the same silver or black wrinkle powder-coat as stock, so they match the stock finish of the engine
- Specifications: 3.927 in. bore, 4 in. stroke, 97 in. displacement, 9.7:1 compression ratio with stock heads (9.3:1 compression ratio with S&S 89cc heads or 10.7:1 with S&S 79cc heads)
- Kits include cylinders, pistons, rings and gaskets (head, base and exhaust)
- Made in the U.S.A.
