All my parts Mopar. I will put my 340 against any smallblock. I will scatter parts and quite frankly I don't care. That's racing. I love rebuilding em anyways. Keeps me occupied. Gonna throw a 500 shot on new motor. It may scatter parts but it took 300 fine. I'm waiting to run my heads and got motor ready to test em. I'm not done yet and I will post videos all the way. Here's the meatball behind the curtain in good health finally. Look for future post and videos...
