one thing to mention is the weight difference of the sr being an aluminum block, if there is one, dont really care to check the specs before i write this, but im sure it weighs less (could be wrong), and that would help getting the over-all wieght down for 1/4 miles, the weight of the driver would also matter, how much fuel was in the car, everything related to weight, im not sayin either is better...i just dont get how everyone is all hung up on 1/4 times and hp, hell some of it is just how good the driver is....

just my opinion
