5.7 Hemi Stroker

Swifter why not just buy a supercharger kit?? it might be cheaper and you'd have a tame motor when you want it and a monster when you stomp on it. JMO
Edelbrock just came out with thier supercharger kit, supposed to be the same supercharger that is on the ZR1 vette and Caddy.

A guy at the track has a 08 chally with a 6.1 and a belt driven blower that fits under the stock hood. It also has head work and a cam and long tube headers. Street car with 78K miles. Says it has 500 HP at the wheels and with a lousey burnout (no traction off the line) it still runs a 7.37 1/8.

If I had one of those I would have to do about the same to it.
