Oh by the way, this has a Paxton blower on it. Haven't yet gotten around to messing with it much. Does your Dart have one? I don't know much about tuning an engine with a blower. But it sure runs good when it kicks in!
Yep, just use it to actuate the relay. My Dart had a B&M blower on it until this year when I built a new 500 horsepower 418 stroker. The blower.was a lot of fun. I bought it from Dick Landy in 1988. Got to talk to him, he was a nice guy.
