churchie Posted October 28, 2009 Share Posted October 28, 2009 Geday !! The block you have is the same as the one i have, it is classified as a truck or industrial block. Best thing is it a high nickel casting and that makes it good for modifications and machining. Quote Link to comment Share on other sites More sharing options...
JDG109 Posted October 29, 2009 Share Posted October 29, 2009 The Suffix code on the Engine Stamp might be incorrect as T5A doesn't seem to exist.. mine was wrong also .. took me forever to figur out they used 4 for a Y. Might not be T5A .. something else similiar? The block was made on 10/25 @ mckinnon though. http://www.nastyz28.com/chevy-engine-code-stampings.php Quote Link to comment Share on other sites More sharing options...
