NASCAR issued a Technical Bulletin today to NASCAR Home Tracks Members which contained the NASCAR Whelen All-American Series Late Model Stock Car rule changes.

Notable changes include the addition of the Chevrolet Built “upgrade” which has been known as the “spec” engine for the last season and the Harrington Enforcer engine. Also notable is the elimination of the Ford, Chevrolet and Dodge built engines as of 2019.

The Chevrolet Built “upgrade”, Ford SR347, the Harrington Enforcer and the GM 604 crate will be the only engines allowed to compete by NASCAR rules in 2019.
