Need Advice... Real Bad-like

["Todd Wallis" <cyclone@xxxxxxxxxxxxx>]

I have pulled the 360 out of my 1970 Rebel (standard trans) and plan to put 
it in my Javelin (with a 904).

Obviously the flywheel will bolt right up but am I going to have a engine 
balance problem?

Is the only solution to break the engine down entirely and have it all 
balanced?

Thanks,
