I am building it myself so that's why I want to know the rules and take them to the limit. Going to be a father son project ( my dad raced SS/A with a factory Hemi Dart years ago with a car called Old Trapper) .
The biggest dilemma is who makes the best heads ?
Probably shake the car down with a 615 B1 engine to get the bugs out then switch to the Hemi.
Maybe have the car done late 2008 depends how the Outlaw 10.5 car does.
