I know there are quite a few aircraft enthusiasts here so i'm hoping you guys can point me in the right direction. Is there someone i can get stats on take-off acceleration of normal commercial airliners? I'm wondering which ones would push me hardest into the seat :-)

Not really since it's not a stat airplanes use. Just look on Wikipedia for max thrust compared to max takeoff weight, that'll give you an idea.
In my experience most airliners are similar, but I've never been on a wide body. The most noticeable 'oomph' I've felt was on a Citation Sovereign with a basically empty load, that thing had plenty of power

The problem here is that under most circumstances full power will not be used, and therefore you will not get the maximum shove. It's called derated power and is calculated based on weather, load and a host of other variables. Lightly loaded aircraft going on a short flight on a cool, dry day will result in the minimum power being used to safely accomplish the takeoff. It's better on the engines, and better for fuel efficiency, but isn't fun in comparison to a full-throttle takeoff.
Calculating this should be easy. Take the MTOW (maximum takeoff weight and divide by the maximum thrust provided by all engines.
If maximum performance is what you're after, always choose a twin. If an engine fails at takeoff, the other one needs to carry the entire load, and therefore will be more powerful than those on a four-engine aircraft like an A340-300. LAN has an interesting problem with their A340-300s - since the engines are optimally sized for cruise and there are four of them, they don't need to be very powerful (and aren't). On a flight out of Chile to Europe, the aircraft will need to fly several hundred miles in the wrong direction to get enough altitude to cross the Andes. But if an engine were to fail on takeoff, the most likely time for one to let go, they are only down 25% of their thrust as opposed to 50% on a twin.
If you want the maximum thrill ride, you'll want to be on an American Airlines 757 taking off from John Wayne Airport in Orange County CA. They have a special noise abatement procedure as to not piss off those in the mansions and estates in Newport Beach. First, they stand on the brakes and spool the engines up for maximum power. Once they get takeoff clearance it's like a shot off of a carrier - fast and violent. After takeoff, instead of a normal 3 degree climb, they go for 5 degrees to get altitude quickly. They then throttle back to quietly pass over Newport, and the sudden change in thrust settings makes you almost seem weightless for a moment. Once they pass over Newport they get back on the throttles and resume a normal climb procedure. After that it's a normal flight, but those first few minutes are an absolute blast.
The reason I recommend an AA 757 is for a couple of reasons. First, the 757 of any flavor has an amazing power to weight ratio, and is a real hotrod in the air; sexy, efficient and fast - the best of all worlds. Second, when AA bought theirs they were planning to use them at a lot of hot and high airports in Central and South America. As such, they specified the Rolls Royce RB211-535E4B engine which has the highest thrust of any engine on the 757. Ridiculously powerful, and makes those takeoffs at John Wayne a real treat.

I have done this departure, and it's awesome. But I was in a 737.
I remember the old days of the 707 and 727. They used to sit at the end of the runway with the brakes on, run up the engines and then release the brakes. There was a definite kick in the pants on those takeoffs.
