One for a 440 here, though I'm a little biased. But the 440 beats the HEMI to the legal street limit (60mph). Easier to make hp at less cost, easier to maintain (HEMIS are a pain in the arse to get running right, all the time. 426 HEMI has the shock and awe at car-shows, but for me the 440 is the best allround engine 4bbl or 6. The 440 also weighs a hell of a lot less, which in a way makes up for some of that hp.
