Chevrolet 383 Stroker Build - Junkyard Heap To 383 Neat, Part 1 Of 2 Photo Gallery
Since the block was already bored out to 4.030, Hernandez decided to do a really light hone to clean up the imperfections in the cylinder walls. Since I am planning on using the motor for autocross and street use, setting the motor up a little loose is a good thing. When a complete engine is cold started the internals will start to warm up and tolerances will become tighter as the engine reaches operating temp. Give the machinist/builder your desired use to properly set the piston-to-cylinder wall tolerances.
