The Ultimate Guide to the Chevy 383 Stroker
|
These engineering drawings from SRP illustrate the difference in compression height (CH) of a typical 350 piston with 1.560-inch CH (right) versus a 383 piston using a 6.00-inch connecting rod, requiring a much shorter 1.125-inch CH (left). Note how the shorter compression height pushes the wristpin into the oil ring, requiring an oil ring support rail. View Related Article
