**1973 bastard 340 balance??**

louis, if it has thewrong balance that motor will be jumping around,feels like it anyway.it won't be any kind of slight. your prob right to just get it out of there.man hitting that 410 with a 400 shot, it's gonna be a monster!:glasses7:

Yeah now I am really busy working so I don't know how fast I will get out there for the swap...... I need to buy a converter too! I already have a brand new Neutral Balance B&M Flex plate and ARP hardware for it.
