4 Chevrolet’s crate motors are based on the newer block design with a one-piece rear main seal. This block isn’t normally used for racing, so it requires a little thinking ahead. For example, this block uses a camshaft thrust plate which requires a cam with a smaller bolt pattern diameter for attaching the timing chain sprocket. All of the timing and valvetrain parts we ordered are the older style with the wider bolt pattern diameter, which means we can’t use the thrust plate. View Related Article
