Engine builder Northeast

I greatly appreciate the advice, that’s one of the only things I don’t like about being a Mopar owner. Chevy information/parts are just so cheap and plentiful. What does BHJ stand for? Sorry I’m kinda new and don’t know a whole lot yet. This is the most I’ve ever posted on a forum and I’ve been a member of some of them going on 11 years lol. If you can point me in the direction of the butts I need to kiss I’ll get my chapstick.
