This universal liner is intended for machine-shop style engine work, so block preparation, pressing, and final machining should be completed according to the engine builder’s procedures. Confirm application details against the vehicle’s engine specifications before ordering, especially on mixed-year classic platforms such as Jeep and Chevrolet truck applications.
