Yeah but being biased doesnt really stray from the facts lol. I know this all depends on how each motor is built but assume there both built the same way outside of bore and stroke is there a signifigant advantage?
Well...ALL 400 blocks are not stronger. Just certain year models and I don't know which ones. NONE of them however are weak. The rod to stroke ratio is a big reason they are such good engines. Also they end up with a much lighter reciprocating assembly. Makes for more poawer and quicker revs. They are a good combination all the way around. That being said, in your case, I would stick with the 440 because you already have dedicated parts for that.
