Ok, i have to clear things up. Everytime i bring up my car my dad asks me about the flex plate and why it causes vibrations, his fight is that everything has a true balance to it. so why does the 250 flexplate cause vibrations on a 302?
a 302 is externally balanced with a 28 or 50 oz weight on the flexplate and the balancer. A 6 is 0 balance so it throws it out
