Does anyone know the part numbers shown in Buick parts books for Stage 2 pistons for 400, 430 and 455? How do these compare to the part numbers stamped on the actual parts? What are the numbers stamped on the parts for each of the three sizes? Dan
The parts book numbers I have for Stage 2 piston and pin are: 1394179 (400 cid) 1394180 (430 cid) 1394878 (455 cid) Does anyone know what numbers are stamped on the actual piston for each engine size? Thanks! Dan
