thanks guys! so tell me about this internal balancing. just like a 350 I take it? so the 400 was an externally balanced engine? flywheel and balancer? I would imagine the internal balancing would be the way to go for sure!
I`ll look more into this 400 block, from all the reading I did last night it looks like it`s exactly what I`m after. what about towing say a 5th wheel or my heavy ole boat? any heating issues? sounds like a myth?

thanks alot guys,
Ron
