Yes, that's true, there's plenty of horsepower available. Even enough to (shock horror) climb on one engine at blue-line speed if necessary - at least it would with just me and my instructor on board!
Not sure I'd describe the take-off a "rocket-like" - but I should probably put that in context by pointing out that I was flying the Aztec at the same time as I was doing aerobatics, so I had other relatively high horsepower aircraft to compare it to. If you're moving to the Aztec from a PA28-140, then yes, I'd guess it is rocket-like.
(Should probably clarify the "at the same time" bit a little more - I was flying the twin in the morning, and the aeros in the afternoon, not doing aeros in the twin!)
