I just purchased a 55 Chevy 2 door post and I'm contemplating installing a 383 stroker engine in it. I have been reading the spec's from the various engine builders who are selling 383 stroker engines on Ebay. I notice that some of the 383 engines being sold on Ebay have was called: Hypereutectic pistons installed. Has anyone had any type of problems with this type of pistons? Thank you for your support.
